On the Crabs of the Family Ocypodidae in the Collection of the Raffles Museum M. W. F. TWEEDIE
Reprint from Bulletin of the Raffles Museum, Singapore, Straits Settlements, No. IS, August 1937 On the Crabs of the family Ocypodidae in the collection of the Raffles Museum hy M. W. F. TWEEDIE M. W. F. TWEEDIE On the Crabs of the Family Ocypodidae in the Collection of the Raffles Museum By M. W. F. TwEEDiE, M.A. The material described in this paper has been collected for the most part during the last four years, mainly in mangrove swamps around Singapore Island and at a few localities on the east and west coasts of the Malay Peninsula. The greater part of the paper and most of the figures were prepared at the British Museum (Natural History) during August and September, 1936, and my grateful acknowledgments are due to the Director for permission to work there and for facilities provided, and particularly to Dr. Isabella Gordon for her unfailing help and encouragement. I wish also to express my thanks to the Directorates of the Zoological Museums at Leiden and Amsterdam for permission to examine types, and for the helpfulness and courtesy with which I was received by the members of the staffs of these museums. Finally acknowledgments are due to Prof. Dr. H. Balss, Dr. B. N. Chopra and Dr. C. J. Shen for their kindness in comparing specimens with types and authentic specimens in their respective institutions. The mode adopted for collecting the material may be of interest to collectors of Crustacea, and possibly other invertebrate groups, in the tropics. It was found that if crabs, especially Grapsidse and Ocypodidse, are put straight into alcohol, they tend to die slowly and in their struggles to shed their limbs and damage each other, so that often less than 10% of the collection survive as perfect specimens. -

It is widely distributed in the southern part of the basin (mainly African coast) and only recently it has been reported also from Sicil- ian Ionian sea. The present record is the first for Italian peninsula and the northernmost record of O. cursor in the Mediterranen Sea. INTRODUCTION The tufted ghost crab Ocypode cursor (Linnaeus, 1758) is a semi-terrestrial burrowing brachyuran of nocturnal habits generally found in supratidal and intertidal sandy beaches (STRACHAN et al., 1999). The species is the only member of the family Ocypodidae occurring in the Mediterranean Sea; specifically, it is characterized by a disjoint distribu- tion, comprising the eastern Mediterranean Sea and tropical coasts of the eastern Atlantic Ocean as far south as northern Namibia, with the exclusion of the western Mediterranean. -

These crabs have been used as ecological 17 indicators of the levels of anthropogenic impacts on sandy beaches. Our aim is to report the 18 variety of burrow architecture types constructed by ghost crabs Ocypode quadrata on 19 beaches of Maceió, Brazil. We found 20 types of burrows that differ in shape (number of 20 axes, number of openings, orientation of blind end, number of branches). The slash-shaped 21 burrows (type C) were the most frequent shape, followed by types K (spiral) and E (Y- 22 shaped). -
Description of the First Juvenile Stage of the Fiddler Crab Minuca Mordax (Smith, 1870) (Crustacea, Decapoda, Ocypodidae)
Volume 56(14):163‑169, 2016 DESCRIPTION OF THE FIRST JUVENILE STAGE OF THE FIDDLER CRAB MINUCA MORDAX (SMITH, 1870) (CRUSTACEA, DECAPODA, OCYPODIDAE) SALISE BRANDT MARTINS¹² MURILO ZANETTI MAROCHI¹³ SETUKO MASUNARI¹⁴ ABSTRACT The first stage of the fiddler crab Minuca mordax is described here. Zoea larvae obtained from four ovigerous female were reared in the laboratory until the development of the first crab stage. The development from zoea I to the first juvenile instar lasted 35 days after hatching. The first crab stage of Minuca mordax can be morphologically distinguished from those of Minuca burgersi and Leptuca cumulanta by a 2‑segmented antennule endopod (3‑segmented in M. burgersi, unsegmented in L. cumulanta), an unsegmented maxillule endopod (2‑seg‑ mented in M. burgersi and L. cumulanta), and a 4‑segmented first and second maxilliped endopod (respectively unsegmented and 5‑segmented in M. burgersi and L. cumulanta). The three species have the following characters in common: segmented peduncle of antennule 2; endopod of antennule unsegmented; presence of aesthetascs on the antennule; peduncle of an‑ tenna 3‑segmented; flagellum of antenna 6‑segmented; mandible 3‑segmented; maxilla with coxal and basal endite bilobed; first, second and third maxillae with exopod 2‑segmented and abdomen with six somites that are wider than long.

This species is distrib- uted in the Western Atlantic Ocean, from the Gulf The former fiddler crab genus Uca Leach, 1814 of Mexico to the Rio Grande do Sul state, southern was composed of approximately 104 species, with 12 Brazil (Bezerra, 2012). -
Uca Rapax (Mudflat Fiddler Crab)
UWI The Online Guide to the Animals of Trinidad and Tobago Ecology Uca rapax (Mudflat Fiddler Crab) Order: Decapoda (Crabs, Lobsters and Shrimps) Class: Malacostraca (Crustaceans: Crabs, Sand-hoppers and Woodlice) Phylum: Arthropoda (Arthropods) Fig. 1. Mudflat fiddler crab, Uca rapax. [http://ocean.si.edu/mangroves, downloaded 10 March 2016] TRAITS. The mudflat fiddler crab Uca rapax is considered dimorphic since the males have a large claw on one side of the body (Fig. 1) and the females have two small claws. Males are also larger in body size: in Brazil, the carapace width at maturity was 13-15mm in males and 11- 12mm in females (Castiglioni and Negreiros-Fransozo, 2004). Both females and males are generally greyish-white in colour, but green to blue can be seen in the large claw and the eyestalks. Colour is dependent upon environmental factors, and hints of orange and yellow are also found in the claws. Fiddler crabs are darker during the day time and light during the night (Tpwd.Texas.Gov., 2016). DISTRIBUTION. Uca rapax is found along tropical coasts of the USA (southern Florida, Texas), West Indies and the Caribbean, and Brazil (Fig. 2). HABITAT AND ACTIVITY. As the name suggests (mud fiddler crab), they reside in intertidal zones of muddy areas of the salt marsh and mangroves (Figueiredo et al., 2008) (Fig. 3). The soft mud is not only home to these creatures but also their feeding ground and protection. Uca rapax are diurnal, skilled at burrowing into the mud, creating holes that provide a nest for their young, privacy for mating, for sleeping and in the colder regions “hibernation” during the winter UWI The Online Guide to the Animals of Trinidad and Tobago Ecology (Gcrl.Usm.Edu., 2016). -

Such data are necessary for implementing more efficient monitoring programs that quantify the dynamics of key ecological attributes on sandy beaches. This article contributes to the bioecology of ghost crabs from subtropical Praia Brava, Itajaı´, Santa Catarina. Ocypode quadrata occurs in sandy beaches along the tropical–temperate western Atlantic, from Rhode Island (US) to Rio Grande do Sul (Brazil). During 14 consecutive months, a total of 649 specimens were captured: 255 females (39%), 241 males (37%), and 153 juveniles of undetermined sex (24%). Highest densities were recorded in June and November, with a total of 1,900 burrows distributed along the beach (56.95%) and dunes (43.05%). Sixteen natural diet items were identified for this crab, with a larger participation of Apis spp. (38.97% of relative volume). In the local food web, the ground-burrowing owl Speotyto cunicularia was the main crab predator. -

Coastal Crabs from Devbagh, Karwar
Karthikeyan S. COASTAL CRABS FROM DEVBAGH, KARWAR blog : www.wildwanderer.com email : [email protected] COASTAL CRABS A walk along the beach is something most people would enjoy. When we see crabs trying to run away from our path, often the child in us comes to the fore and we run about chasing them! It was during my first visit to Devbagh, Karwar that I was taken by surprise by the beauty of the few crabs that I saw. Even as I arrived at the jetty, I saw a large crab moving about on the rocks. It had stunning red legs. As I approached it, it disappeared under the rocks. On the same trip I also chanced upon my first fiddler crabs. Thus began my tryst with crabs. Over the years, during the many visits to Devbagh, I have spent considerable amount of time looking for crabs both on the shore and also in the mangroves around Devbagh. I have thoroughly enjoyed waiting for them to come out of their burrows, watching them at work, and in the process I have also managed to photograph a good number of them. Crabs are a very important and easily noticeable component of the coastal and mangrove ecosystems. They have adapted to the tidal actions and also the varying salinity that is so typical of delta areas. They are considered to be the most predominant species particularly in the mangrove forests. This also could be because many crabs use the mangroves for their very survival. They feed on the leaf litter and other organic matter. -

Karwar Research Center of C.M.F.R.I., Karwar 581301, Karnataka, India [email protected] ABSTRACT In the semi-terrestrial crab family Ocypodidae, the ghost crab Ocypade cerataphtha/ma (Pallas) represents the sandy shore ecosystem. Of the eleven species of the genus Ocypade recorded from Indo-West Pacific region (Serene, 1968), the ghost crab O.cerataphtha/ma was reared under laboratory conditions at Karwar. The larvae passed through 5 zoeal stages before reaching a megalopa stage. The temperature and salinity of the water during the experiment ranged from 23-26°C and 30-33 ppt. respectively. The complete metamorphosis took nearly 40 days before reaching first crab stage. Larval descriptions are given in the text. The larvae have a characteristic globose shape. Based on the presence of knobs on the abdominal segments, zoeae of the genus Ocypode can be grouped into two groups: one group having knobs on first and second abdominal segments and other group devoid of these knobs. In general, the megalopae of different species of Ocypodiae resemble each other in their gross morphology. Globosely shape, posterio-Iateral depressions for reception of fifth pair of walking legs, and lateral depressions where other ambulatory legs fit are common characters in these species.
