common squid of the Atlantic coast, Loligo pealei, in the laboratory. The first time he fired his electronic flash, the animals retired to separate corners of the tank and gave him a nasty look. Subsequently, Sisson found that he could condition his subjects to a con stantly flashing light, and after that the amorous squids didn't even look up as he photographed them. The young of most shore squids and cuttlefishes are well developed when hatched and look much like their par ents (pages 402-3). In many oceanic squids, however, the young hatch out as larvae. Some of them are weird creatures indeed. I have always loved to watch the young of the orange back. They swim about slowly in the water, looking for all the world like miniature elephants, with a long, tubelike structure hanging down between their arms. Actually the "trunk" is formed by the two tentacles, which remain fused together until the animal reaches its juvenile stage. 409 Bony fish head, gnawed off by Loligo's beak, floats away as the squid prepares his meal. Turning the fish body lengthwise (below), he strips off the flesh, leav ing skeleton and tail intact. Squids feed on anything they can catch, from plankton to large game fish and even other squids. Dissections of squid stomachs reveal undigested beaks, proof of cannibalistic feasts.
