Compared to the occurrence its compatriote C. melanodactylus, this species found in large numbers. The relationship is mutualistic, with the species occupying a niche similar to that occupied by the more colorful Trapezia species . Cymo species , however are typically drab in coloration, and usually have a layer of algae growing on their carapace. Very common and is considered a coral symbiont , with the caveat that such symbiosis are a tradeoff between the coral and the crab, the coral gains protection and house cleaning services while giving up a few polyps, mucus and captured/ settled food particles in exchange for those services. A healthy coral Editors: Ramin Ketabi;Shahla Jamili (IFSRI) should have no problem repairing or replacing lost polyps, but again, in an aquarium environment, an eye should be kept on the coral for excessive damage being done due to the coral being unable to recover as fast as or faster than the damage being done by the crab. As obligate coral symbionts, the survival of this species is directly associated with the conservation of coral reefs, which are under threat from coastal development and land reclamation resulting in heavy siltation, dumping and pollution. Members of the order Decapoda are mostly gonochoric. Mating behavior: Precopulatory courtship ritual is common (through olfactory and tactile cues); usually indirect sperm transfer. Habitat: Coral Reef; Marine; depth range 0 - 17 m Distribution: Persian Gulf (Iran, Kish Island) , Red sea, Madagascar, Seychelles, Somalia, Red sea, Fiji, Japan, Maldives, Sri Lanka, India..

GARTH Allan Hancock Foundation Univer5ity of Southern California 2 and Eniwetok Ma rine Biological Laboratory Introduction The brachyuran decapod crustaceans of the Marsh all Islands have been reviewed by Balss (1938) and by Miyake (1938, 1939). These reports stem from the German and Jap anese occupations, respect ively, the former being the result of the Pacific Exp edition of Dr. Sixten Bock, 1917-1918, the latter th e result of the Micronesia Expedition of Prof. Te iso Esaki, 1937-1938. According to Fosberg (1956, p. 1), J aluit Atoll was the headquarters of both the German and the Japan ese administrations, a fact that accounts for the preponderanc e of record s from the southern Marshall Isl ands. Additional coverage of the southern Marsh alls was provided by the 1950 Arno Atoll Expedition of the Coral Atoll Program of the Pa cific Science Board, the decapod crustaceans collected by Dr. R. W. Hiatt having been reported by Holthuis (1953). Carcinologically speak ing, the northern Marshalls ar e less well known, collections having been made only at Likieb Atoll by both Dr. Bock and Prof. Esaki and at Kwajalein Atoll by Prof . Esaki alone. Except for the shrimps, reported by Chace (1955), the extensive collections made in connection with Operation Crossroads in 1946- 1947, which includ ed Bikini, Rongelap, Rongerik, and Eniwetok atolls (Fosberg, 1956, p. 4), are at the U.S. Nationa l Museum awaiting stud y.

Brachyuran Crabs Symbiotic with Scleractinian Corals: a R Eview of Their Biology1
Brachyuran Crabs Symbiotic with Scleractinian Corals: A R eview of their Biology1 PETER CASTRO Biological Sciences Department, California State Polytech11ic U11ii1ersity Pomona, CA 91768 INTRODUCTION The brachyuran crabs constitute one of tb.e most diverse components of coral reef communities. Serene (1972) has estimated that more than 500 of approxi mately 2,000 species of Indo-West Pacific brachyurans are inhabitants of coral reefs. Many of these species are associated in one way or another with scleractinian corals. Some of these are found living on dead coral or coral rubble while others arc facul tative or obligate associates of living coral. This review will be limited to tb.ose brachyurans which are obligate associates of living scleractinian corals. Various terms have been used in designating these as well as other associates: "commcnsals," "parasites," "cpizoics," "cpibiotes," or simply "associates." Often these organisms are placed in a category after making assumptions on the presence or absence of "harm" or "benefit" in the partners. Here they will be referred to as "symbionts" following the original definition of symbiosis as different species living together (de Bary, 1879; see also Hertig et al., 1937). Brachyurans which are normally restricted to live corals are therefore considered obligate symbionts. Facultative symbionts utilize live corals only as an alternate and often temporary habitat. Symbiosis may be best visualized as a broad category of heterospecific as sociations involving a wide range of adaptive interactions. Differences between some symbiotic and predatory interactions have been outlined by Noble and Noble (1971). The criteria of harmfulness and of metabolic dependency (sec Smyth, 1962; Cheng, 1967) have often been used in classifying symbioses.

/. mar. biol. Ass. India, 15 (1): 195-212 DECAPOD CRUSTACEANS INHABITING REEF-BUILDING CORALS OF CEYLON AND THE MALDIVE ISLANDS 1 JOHN S. GARTH Allan Hancock Foundation, University of Southern California, Los Angeles, California, U.S.A. ABSTRACT Living corals were collected at Galle, Ceylon, and at ten localities in the Maldive Islands. Fiftyfive coral heads, 10 of the family Pocilloporidae and 45 of the family Acro- poridae, were examined for decapod commensals. Shrimp found exclusively in Pocillo- pora, together with frequency of occurrence, if more than once, were Alpheus lottini(9) , Harpiliopsis beaupresi (5), H. depressus (5), H. spinigera, Philarius sp. (probably gerlachei, Fennera chacei, and Tkor maldivensis. Crabs found exclusively in Pocillopora were Trapezia cymodoce (8), T. ferruginea (6), T. aff. wardi (3), Domecia hispida (3), Trapezia areolata, T. aff. danai, T. aff. maculata, T. aff. tigrina, and Cymo quadrilobatus. Shrimp found exclusively on Acropora were Jocaste japonica (17), Coralliocaris superba (3), Jocaste lucina (2), Coralliocaris graminea (2), C. nudirostris, C. venusta, and Periclimtnes lutescens. Crabs found exclusively or Acropora were Tetralia glaberrima (33), T. heterodactyla(\9), Cymo deplanatus (13), C. melanodactylus (4), Domecia glabra (6), Crabs found in Ceylon but not in the Maldive Islands were Trapezia aff. tigrina, T. areolata, and Cymo (?) on Pocillopora and Cymo deplanatus on Acropora. Shrimp found in the Maldive Islands but not in Ceylon were Philarius sp. (probably gerlachei), Harpiliopsis spinigera, Fennera chacei, and Thor maldivensis on Pocillopora and Coralliocaris nudirostris, C. superba, C. venusta, Periclimtnes lutescens, and Jocaste japonica on Acropora.

The next author was Alcock 1895-1 goo who, in his papers on the crabs of India lists 51 (-]- i ?) crabs from the "Persian Gulf." Nobili 1906 a records 67 species of crabs; but in spite of the title of his paper (Mission J. Bonnier et Ch. Perez. Golfe Persique 1901) several of his species are from other seas, especially from the Red Sea (cf. his list of stations, loc. cit., p. 14) ; in reality only 50 -]- 2 ? of his crabs are from the Iranian Gulf. MacGilchrist 1905 makes mention of 7 species; Klun zinger 1913 and Chopra & Das 1930 record one species each. The present paper comprises the total fauna of marine Brachyura of Iran, 163 species (-f- the fresh water crab Potamon ibericus). The material of the Danish Expeditions was collected by Dr. G. Thorson (18.II.-22.IV. 1937) and by Dr. B. Loppenthin (9.1.-27.IV. 1938) during the fishery investigations carried out for the Iranian Government. Collections of marine animals were made in 156 localities (see map fig. i), evenly distributed along the Iranian coasts from Bendar Shahpur in the northwest to Baluchistan in the southeast.

6. Brachyuran Decapod Crustaceans of Coral Reef Communities of the Seychelles and Amirante Islands
CLnMr i&ll^ CRUSTACEA LIBRARY SMITHSONIAN INSTITUTION RETURN TO W-119 6. Brachyuran decapod crustaceans of coral reef communities of the Seychelles and Amirante Islands John S. Garth Introduction Following his participation in Te Vega Cruise B to the Maldive Islands, South India, and Ceylon, as a member of the U.S. Program in Biology of the Interna- tional Indian Ocean Expedition, during which decapod crustaceans inhabiting hermatypic or reef-building corals were studied, the writer was deluged with collections from other western Indian Ocean localities, including Kenya, Somalia, and the Red Sea. Of them none has proved more rewarding than a collection from corals made in the Seychelles and Amirante Islands in 1966 by A.J. Bruce, which are the subject of the report that follows. The excellence of this collection consists in the great variety of corals sampled, exceeding any compa- rable collection from any locality known to the writer, the segregation of the decapod crustaceans according to coral host and individual coral head, and the accurate identification of the coral hosts by J. W. Wells, an internationally recog- nized authority. Years of experience and expeditions to several of the world's coral-producing regions were required before the writer learned the importance of the simple procedures essential to success in this multidisciplinary endeavour: (1) the separa- tion of the living coral from the dead, (2) the segregation of the live corals and their contained commensals according to host species, and (3) the retention of a fragment of each coral for later positive identification by a specialist. It is only when these procedures are adhered to consistently that reliable results can be expected bearing on host specificity, incipient speciation, competitive exclusion, recruitment, and predation.

Contents Introduction and historic review 3 Systematics 6 Thalassinidea 6 Anomura 8 Brachyura 33 Additional records 63 Biogeography 69 Acknowledgements 69 References 70 Index 81 Introduction and historic review The Kimberley region of northwestern Australia extends from the vicinity of Broome (17°58'S, 122°14'E) to the Western Australian-Northern Territory border (14°26'S, 129°00Έ) and is one of the least accessible areas of Australia. The coastline is largely uninhabited between a few small isolated towns (Broome, Derby, Wynd- ham) and land access to the coast is impossible for most of its length. The remoteness and inaccessibility of the Kimberley coast have resulted in only limited European exploration and biological research. Early maritime explorers of the area included the Dutch navigator Abel Tasman in 1644. William Dampier sailed along a short stretch of the coast in the "Cygnet" in 1688, making land-fall on the west side of King Sound where a small biological collection may have been made (Marchant, 1988).
