On the ability of Cephalopod larvae to active movement

As a result of observations on the behaviour of Loligo forbesi Steen. the larvae were found to start to actively swim directly after hatching, ejecting water from the funnel. The motion of larvae can be divided into two types: slow, quiet swimming and motion by strong frequent rushes. Parameters of these types of movements considerably differ. Unlike adult specimens, the direction of larval motion is irregular due to the underdevelopment of morphological peculiarities regulating larval motion
