Kakati, V S (2005) Larval development of Ghost Crab Ocypode ceratophthalma (Pallas) under laboratory conditions. In: Seventh Indian Fisheries Forum, 8-12 November 2005, Bangalore.
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.
