摘要: Cephalopods, especially squids, are the most swift-moving of all aquatic invertebrates. Any such animal requires sensory devices for proper spatial control. No wonder then that cephalopods — during course evolution and probably in competition with fish (Packard, 1972) developed sophisticated sense organs, statocysts, provide animals information about their attitudes movements space. Among invertebrates, these organs reach highest level complexity octopod decapod cephalopods, receptor systems detection both linear (gravity) angular accelerations (Budelmann, 1980, 1988).
