Swimming attitudes of young lobsters in the first free stages; a, lobster swimming with body bent in the usual quadrant form, the head directed downward and often at a greater angle; the swimming branches (and the permanent limbe rather more than here shown) directed backward, in "posterior" position of Hadley; resulting movement upward and backward; b, young lobster playing cannibal, swimming astride the carcass of another which it has nipped at the junction of the carapace and abdomen and holds with its prehensile legs; c, swimming with the thoracic legs directed forward; in "anterior" position of Hadley; resulting movement upward and forward; d, rising position occasionally assumed; e, slowly moving or "floating" position sometimes observed; f, lobster "standing on head," apparently probint the bottom with rostrum, but really too weak to rise
