This species tends to grow on less solid and loose substrates of the ocean floor. ( Jones, 1977; Rossi-Snook, 2011 ) The optimum temperature for adult Scleractinia coral is between 25 and 29 degrees Celcius; the absolute minimal temperature is 18 degrees Celcius. Because it has a single-celled symbiotic algae within its cells, grooved brain coral needs to be at depths where light can penetrate the water. As a result, this species has a depth limit of approximately 50 meters. Diploria labyrinthiformis grows throughout the year around Bermuda and in other areas off the Carribean. This coral can live in high areas of sediments. Members of the genus Diploria are found in high abundance on Bermuda's reefs when compared to other corals. This high abundance is due to the fact that genus Diploria has lower juvenile mortality rates than other coral groups. ( Cohen, et al., 2004; Logan, et al., 1994; Rossi-Snook, 2011; Smith, 1992 ) The valleys are 5-10 mm wide, up to 6 mm deep and u-shaped in a cross section. The ridges are wider than valleys, up to 15 mm, and have a concave profile with edges 2-4 mm higher than the rest of the ridge. Right angles of the plates, or septa, make it look like there are double combs in the valleys. Crests, or costae, of the septa form across the valley walls.http://schlammatlas.de/en/node/17785 Grooved brain coral tends to grow to longer lengths when inhabiting shallow waters. Colonies of D. labyrinthiformis can be one to two meters in diameter. Grooved brain coral can be a variety of colors including tans, yellows, and grays. ( Logan, et al., 1994; Rosen and Darrell, 2011; Rossi-Snook, 2011; Spalding, 2004 ) Diploria labyrinthiformis is fertilized internally and then releases eggs into the ocean. The eggs hatch into swimming planktonic planulae larvae, which settle on an appropriate substrate, where asexual reproduction begins. Secondary polyps are formed, which develop to adult polyps. This species can grow at a rate of 3.5 millimeters per year. ( Alvarado, et al., 2003; Rossi-Snook, 2011 ) The typical spawning season of grooved brain coral is from late May to late June. Spawning likely begins for this species as a result of environmental cues such as high air temperature, low number of solar hours per month, low wind velocity, and initiation of the rainy season. ( Alvarado, et al., 2003 ) Eggs and spermatic cysts are located towards the aboral (opposite the mouth) part of the mesentery. ( Alvarado, et al., 2003 ) However, members of the genus Diploria are found in high abundance on Bermuda's reefs when compared to other corals. This high abundance is due to the fact that genus Diploria has lower juvenile mortality rates than other coral groups. ( Smith, 1992 ) The polyp coral will retract it's tentacles in the daytime, and will extend them to feed at night. ( Rossi-Snook, 2011 ) This coral also has zooxanthellate algae. The symbiotic algae photosynthesize and supply the coral with nutrients and energy for calcification and growth. ( Rosen and Darrell, 2011; Rossi-Snook, 2011 ) Zooxanthellate algae live within the cells of D. labyrinthiformis. The single-celled algae receives protection and feeds on coral waste, while the coral receives nutrients and energy from the algae.https://cottonsauction.com/images/c50-manual-transaxle.pdf ( Rossi-Snook, 2011 ) It is the second largest ocean in the world after the Pacific Ocean. More specifically refers to a group of organisms in which members act as specialized subunits (a continuous, modular society) - as in clonal organisms. Ecotourism implies that there are existing programs that profit from the appreciation of natural areas or animals. Coral reefs are found in warm, shallow oceans with low nutrient availability. They form the basis for rich communities of other invertebrates, plants, fish, and protists. The polyps live only on the reef surface. Because they depend on symbiotic photosynthetic algae, zooxanthellae, they cannot live where light does not penetrate. Synapomorphy of the Anthozoa Revista de Biologia Tropical, 54: 859-868.

This paper is the result of processing samples taken between 1972 and 2012. In all, 122 species were identified, 14 of them new (including one new genus). The new species are Tetralophophora (new genus) mesoamericana, Geodia cribrata, Placospongia caribica, Prosuberites carriebowensis, Timea diplasterina, Timea oxyasterina, Rhaphidhistia belizensis, Wigginsia curlewensis, Phorbas aurantiacus, Myrmekioderma laminatum, Niphates arenata, Siphonodictyon occultum, Xestospongia purpurea, and Aplysina sciophila. We determined that about 75 of the 122 cryptic sponge species studied (61) are exclusive members of the sciophilic community, 47 (39 ) occur in both, light-exposed and shaded or dark habitats. Since we estimate the previously known sponge population of Carrie Bow reefs and mangroves at about 200 species, the cryptic fauna makes up 38 of total diversity. Bergquist, P.R.

(1977) Shallow-water sponges of the western Bahamas. Most classic ecological studies have focused on hard-bodied Ecdysozoan taxa (notably Copepoda and Nematoda), whose cuticle allows determination at species-level after fixation, rather than soft-bodied, Spiralian taxa, which most often lose any diagnostic feature in fixed samples. Yet, metabarcoding studies have recently revealed a species-richness of soft-bodied taxa comparable, and in cases superior, to that of Copepoda and Nematoda together. However, given objective difficulties inherent to their study, which necessarily has to be performed on living individuals, and their limited utilisation for ecological and applicative research, taxonomic expertise on soft-bodied organisms has declined over the years, and diversity of these phyla in most areas of the world is presently completely unknown.https://www.sevgiliyevideo.net/wp-content/plugins/formcraft/file-upload/server/content/files/1629b28ced7bd2---cospolich-manuals.pdf Here we present an expert-based survey of current knowledge on the composition and distribution of soft-bodied meiofaunal taxa in Italy, with special references to the predominantly or exclusively meiobenthic phyla Gastrotricha, Gnathostomulida, Platyhelminthes, Rotifera, Xenacoelomorpha, and macrofaunal taxa with conspicuous meiofaunal representatives (Annelida, Mollusca and Nemertea). A total of 638 described species have been reported from Italian coasts; furthermore, the existence of a large number of undescribed species is mentioned. Knowledge of Annelida, Gastrotricha, and Rotifera appears particularly detailed, placing Italy among the best-known country worldwide. In contrast, knowledge of Platyhelminthes and Xenacoelomorpha appears patchy, and limited to few areas. Sampling effort has been uneven, with most species recorded from the Tyrrhenian Sea, while large sections of the Adriatic and Ionian seas have been poorly explored. Results highlight the role that Marine Biological Stations, notably the Zoological Station “Anton Dohrn” in Naples, have had in promoting the study of soft-bodied taxa in Italy. Keywords: Meiobenthos mesopsammon microscopic biodiversity Italy While minute body size, rapid turn-over, and restricted dispersal capability are common traits of meiofaunal organisms, others, such as filiform or flattened body shapes, adhesive structures and static organs are particularly crafted features that allow these organisms to live interstitially among sand grains (see Giere 2009 ). This widely accepted view was to change in later decades. Given these operative difficulties, and the limited utilisation of soft-bodied taxa for ecological studies and applicative research, which nowadays attract most of the funds, it is not surprising that taxonomic expertise on soft-bodied organisms has declined over the years, leading to the current situation where there are few taxonomic experts worldwide, if any.https://yuseigachi.nl/wp-content/plugins/formcraft/file-upload/server/content/files/1629b28d9b1663---Cossacks-2-manual.pdf Taxonomic knowledge of these taxa is consequently patchy and limited to the areas where the few experts have operated. These areas contrast sharply with large part of the planet, from which nothing is known. In Italy, soft-bodied taxa have been the focus of two workshops held in the National Parks “Arcipelago di La Maddalena” and “Isola dell’Asinara”. During the LXXX congress of the “Unione Zoologica Italiana”, held in Rome in September 2019, one session, organised by the “Comitato Scientifico per la Fauna d’Italia”, was specifically devoted to presentation of the state of knowledge of Italian biodiversity. This prompted worldwide experts on interstitial meiofauna to join efforts in order to summarise the present knowledge about diversity and distribution of main soft-bodied metazoan meiofaunal taxa along the Italian coasts. The results are presented here. Material and methods Information on species occurrence and distribution given is mainly based on existing literature. When unpublished information is provided, this is properly detailed. Information concerning new, still unpublished species is also given in the following sections. Distribution maps are based on the biogeographical sectors of the Italian seas, as proposed by Bianchi ( 2004 ). In many habitats, they can be among the dominant organisms: in particular, the algal-symbiont bearer convolutids, such as Symsagittifera roscoffensis (von Graff 1891 ), can be so numerous that, when exposing the photosynthetic partners to light at low tide, they may give the sand a bright green colour (Schmidt-Rhaesa 2020 ). Eighteen nemertodermatid species are currently known worldwide. Italy has been comparatively well studied, and a total of 9 species has been reported ( ). Occurrence of most species of Acoela appears limited to a single sector, with very limited overlap among sectors. Moreover, even distribution of species within single sectors may not be homogenous.glasgowpools.com/contents//files/british-seagull-manual.pdf In particular, within sector 2, relatively close-by areas such as Southern Tuscany and Northern Sardinia have only 13 of the species in common (U.J., own data). Available information does not allow discerning whether this patchy distribution is due to unrepresentative sampling, or indeed reflects restricted species ranges. In any case, present knowledge of composition and distribution of Acoela in Italian waters has to be considered particularly poor. The size of the pie charts is related to the number of species in the areas. Display full size Figure 1. Composition of soft-bodied meiofaunal phyla (a) and major platyhelminth orders (b) in the nine biogeographical sectors of the Italian seas (see text for details). Platyhelminthes The vast majority of marine free-living Platyhelminthes pertain to the meiofauna size class, with the only exceptions of most Polycladida and few representatives of Tricladida Maricola (Cannon 1986 ). However, only a fraction of the coastline has been sampled for most major taxa, and this number may represent just a fraction of the actual diversity of the group in Italy. It is noteworthy that a number of species have been reported from the Croatian coast (Rovinj), and may also occur in the Gulf of Trieste. Exemplary of the poor knowledge on most platyhelminth taxa is the case of Prolecithophora, with 30 Italian species, found during past research in the Gulf of Naples (Riedl 1954, 1959 ) and in Northern Adriatic (mainly von Graff 1891 ), with no recent studies on the taxon whatsoever. The taxonomy of the genus, however, needs a thorough revision with the contribution of molecular data, in order to evaluate the extent of inter-populational variability (Scarpa et al. 2017 ). A few species of Proseriata seem to present extremely restricted ranges. Finally, an important area of endemism for proseriates, and possibly for other meiofaunal taxa, is the Northern Adriatic Sea, where numerous species not found elsewhere occur, only partly published so far (Meixner 1943, M.C.G. unpubl. data). Other taxa (Catenulida, Gnosonesimida, Tricladida, Polycladida) have few representatives in marine meiofauna. The distribution map of described species in the nine Italian biogeographical sectors ( Figure 1 (b)) reveals a strong author’s bias, with the highest number of species, especially Proseriata and Rhabdocoela, reported from the most intensely studied Sector 2. Conversely, most Adriatic species known belong to the Prolecithophora and Macrostomorpha. Knowledge of Sector 3 is mainly based on old records for the Gulf of Naples, with large, potentially highly diverse areas, such as Sicily, which have never been sampled. The same is true for Sector 6. Knowledge for the highly species-rich Rhabdocoela is particularly spotty. It is therefore reasonable to conclude that the 235 species of Platyhelminthes presently known may represent just a small fraction of the diversity of the group in Italy. Gastrotricha Gastrotricha is a phylum of minute, acoelomate worms, phylogenetically allied with Platyhelminthes, with which they form the clade Rouphozoa, nested within the bilaterian Spiralia (Egger et al. 2015 ). Of the about 860 gastrotrich species known to date, 510 species have been described from marine ecosystems; these marine taxa are distributed in 46 genera and 14 families within the two recognised orders Macrodasyida and Chaetonotida (Todaro et al. 2019a; WoRMS, 2020 ). About 140 species have been recorded from over 160 investigated localities along coasts of the Ligurian and Tyrrhenian Seas. A single species has been documented from the micro-sector 4, while 31 species have been found in the relatively restricted area 5, which, however, includes the highly diverse island of Lampedusa. The Jonian Sector 6 hosts 58 species, similarly to the Adriatic Sectors 8 and 9 (59 and 60 species, respectively). It should be highlighted that most records of the Ionian area 6 come from Apulian localities, whereas Basilicata and Calabria coasts have been poorly investigated. Most of the species found in area 8 have been recorded from the Gargano and Tremiti islands, whereas most species from the upper Adriatic Sea, area 9, have been recorded in spotty locations along the coasts of Veneto and Friuli Venezia Giulia regions (e.g., Isola della Cona, at the mouth of the Isonzo river), being the coastal sediment of this sector, and in particular of Emilia-Romagna and part of the Marche coast, made up of fine to very fine sand, and consequently not suitable for most gastrotrich species. While some species seem restricted to one or two biogeographic sectors, most others exhibit a wide geographic range along the Italian coastline, with five Macrodasyida and five Chaetonotida having been recorded in all the biogeographic areas, except micro-sector 4; among these are the macrodasyidan Acanthodasys aculeatus Remane, 1927 (Macrodasyida, Thaumastodermatidae) and the chaetonotidan Halichaetonotus aculifer (Gerlach 1953 ) the most frequently sampled species ( Figure 2 (d)). Notwithstanding the relatively high number of marine gastrotrich species found along the Italian coast and the high number of investigated localities, there are indications that a comprehensive knowledge of the Italian gastrotrich fauna is not completed. Some species seem to be very common and abundant in some areas and rare or absent in others, such as Rotaria laticeps Wulfert, 1942 commonly occurring in any marine habitat in the Northern Adriatic but rare elsewhere. The richest areas in the Italian coasts are the Tyrrhenian (area 2) and the Northern Adriatic (area 9), with more than 60 species each. Yet, no inference can be considered reliable on rotifer distribution, given the extremely small number of faunistic studies in marine habitats. This is a common and known problem in rotifer biodiversity, for which the known species richness of a region is a function of sampling effort and not of biological reality (Fontaneto et al. 2012 ). Only a fraction of the coastline has ever been sampled, and the number of known species, as well as their records, surely represents just a fraction of the actual diversity of the group in Italy. Meiofaunal forms are common and spread across the annelid tree, represented by more than 400 species classified into 25 families (Worsaae 2020 ). While most of these families include both macrofaunal and meiofaunal representatives, 11 of them are considered as entirely meiofaunal (Worsaae 2020 ). Members of these entirely meiofaunal families typically consist of small and comparatively simple forms, grouped in three main lineages: Psammodrilidae, basally branching; Protodriliformia, sister to the remaining Errantia; and meiofaunal Orbinida, nested within Sedentaria (Laumer et al. 2015; Struck et al. 2015 ). A total of nine exclusively meiofaunal families have been reported from Italy, accounting for 44 species. This high diversity is linked to a historically intense sampling effort, which already started in the XIX century and continues nowadays, favoured by the presence of important Marine Biological Stations in the country. Notably, Italy hosts the type locality of one family (Hatschek 1888 ) and 11 nominal species, most of them described around the Zoological Station “Anton Dohrn” in Naples. Indeed, most Italian species are known from Sector 3 (25 species), where the Zoological Station is located, and from Sector 2 (22 species), where workshops on meiofauna have been organised (Curini-Galletti et al. 2012; Martinez et al. 2020 ). In contrast, southern Italy and most of the Italian Adriatic coast remain unexplored to this day. Nerillidae is the most species-rich family in Italy with 16 species, including 4 unequivocally new, still undescribed species (Martinez and Worsaae, unpubl. data). Nerillids are commonly found subtidally in coarse or medium well-sorted sediments. Mesonerilla intermedia Wilke, 1953 and Nerillidium mediterraneum Remane, 1928 are the most common species, recorded from Sardinia, Tuscany, Campania, and Sicily, typically in coarse sandy patches amongst rocks or in Posidonia oceanica meadows (Worsaae et al. 2015, 2019 ). Nerillia antennata O. Schmidt, 1848 is also widely distributed, but prefers coarse or gravelly sediments often along the high-tide (Gelder 1974 ). Protodrilidae is a very diverse family as well, with 14 species recorded in Italy (Martinez et al. 2019 ). The family has been originally described based on specimens found near Messina (Hatschek 1888 ). Most of the early studies on Protodrilidae rely on the work of Piero Pierantoni from the Zoological Station “Anton Dohrn”, who described five new species (three of them considered as valid) and performed very detailed studies on the morphology and development of the group (Pierantoni 1906, 1907, 1908 ). Amongst the Italian protodrilids, Claudrilus hypoleucus (Armenante, 1903) is the most ubiquitous, and it has been found in nearly every published survey of the Italian interstitial fauna (e.g., Pierantoni 1908; Boaden 1965; Magagnini 1980; Curini-Galletti et al. 2012; Martinez et al. 2015 ), although it seems to prefer coarse sediments ranging from 2 to 20 m depth. In contrast, Lindrilus flavocapitatus (Uljanin, 1877) and the three species of Meiodrilus Martinez et al., 2015, are more common in sandy beaches (Martinez et al. 2019 ). Lindrilus flavocapitatus has been exclusively found in the upper layers of exposed gravelly areas at the swash zone, while Meiodrilus species are more common in medium to coarse sediments, where they tend to penetrate deeper in the sediments to avoid wave disturbance. The species of Protodrilus Hatschek, 1882 and Megadrilus Martinez et al., ( 2015 ) are very common in subtidal shell gravel, with a single record of Megadrilus schneideri (Langerhans, 1881) in a marine cave (Curini-Galletti et al. 2012 ). Saccocirridae is represented by four species. Species of the genus Saccocirrus Bobretzky, 1871 are an important component of the interstitial communities in many exposed marine environments such as sandy beaches, where they feed on suspended particles drifting along with the sand grains moved by the wave action (Di Domenico et al. 2014a ). They are non-selective feeders, and they have even been found with ingested microfiber particles in several beaches of the world, including those at the Asinara National Park (Gusmao et al. 2016 ). Three species are found in Italy, exhibiting a strong variation in size, which has been correlated to different habitat preferences in terms of grain size, with S. parvus Gerlach, 1953 in medium sand, S. papillocercus Bobretzky, 1871 in coarse sand, and the (comparatively) enormous Saccocirrus major Pierantoni, 1907 amongst pebbles in Naples and Tuscany (Pierantoni 1907 ). This ecological segregation between species of Saccocirrus and Pharyngocirrus has been found in other regions of the world, such as Brazil or the Canary Islands (Di Domenico et al. 2019 ). The remaining families are less diverse. Dinophilidae is only known for Dimorphodrilus gyrociliatus (O.Schmidt, 1857), described from the Gulf of Naples and thereafter recorded in Liguria and Ravenna, in sediments with algae at the swash-zone. Finally, an unidentified specimen of the elusive family Lobatocerebridae has been reported from Elba Island (Tuscany) (Kerbl et al. 2015 ).
