Clione is a planktonic animal. In the sea and in the aquarium at lower water temperature, Clione usually can be found oriented vertically, with its head up. Clione swims upward or maintains itself at a particular depth by continuous beating of two wings (Arshavsky et al. 1985a,b; Satterlie and Spencer 1985; Satterlie et al. 1985). Any deviation from the vertical orientation evokes a set of corrective motor responses (specific movements of the tail and wings) aimed at restoration of the initial orientation. These reflexes are driven by input from two statocysts. After removal of both statocysts, Clione is not able to maintain any definite orientation and continuously loops in different planes (Panchin et al. 1995a).
