Description Spider conches are common in shallow waters of the Indian coast. Of the eleven species reported from Indian waters, six
species of the genus Lambis are categorised under Schedule IV of the Indian Wildlife Protection Act, 1972. Studies on the
breeding of Lambis spp. are limited Considering its importance, an attempt was made to breed the common spider conch
Lambis lambis, under controlled conditions. The brooders ranged from 152-184 mm/80-400 g in size/weight. They were
maintained on macroalgal diet under static as well as airlift recirculation system. The conch shells, after 4 months of
maintenance, exhibited mating behaviour and laid eggs under captivity during October-December 2010. The morphology
and development of the embryo within the egg filaments, hatching, embryonic and early larval development up to 35 days
post-hatch (dph) is detailed and compared with the similar observation made at Majuro atoll, Marshall Islands.
