Lobsters are carnivorous, their main food has been reported as moUuscan meat, trash fish, squid head etc., in indoor culture system. The Checkerboard helmet, the Phalium areola found to live in sandy areas from low tide to a depth of about thirty feet in Australian waters, also has been reported to feed upon sea urchin after paralyzing with the venom secreted in the snout gland.The violet sea urchin (Temnopleurus cdexandri)ranging approximately between 5 and35 nos./bundle has been observed at Vellapatty in the by-catch of crab/lobster nets.
