This is a tree topper unlike any other! Reminiscent of a freshly made snow angel, these pteropods are actually shell-less sea snails (Clione limacina). Unlike the typical snail, they flap their adapted foot ‘wings’ to get around in the water column. They are extremely small, with the largest species reaching only 5 centimeters long.

It lives in the Arctic Ocean and cold regions of the North Atlantic Ocean. The pelagic marine mollusk Clione limacina (Figure 1 (a)) swims by rhythmically moving its two wings. Each swim cycle consists of two phases, dorsal and ventral wing flexions, which are produced by alternating contractions of antagonistic wing muscles (Figures 1 (b) and 1 (d)). An active swimmer while hunting for its shelled pteropod prey, primarily Limacina helicina Feeding apparatus consists of 3 pairs of buccal cones (finger-like tentacles), 2 clusters of long hooks, and a toothed radula (a chain-saw like tongue) all normally hidden inside the head and body The Clione limacina is approximately an inch long.

3936 appears to be circumpolar, with C. limacina occupying the northern hemisphere and C. antarcticaoccupying the southern hemisphere, primarily in the Antarctic Circle (Gilmer and Lalli, 1990). Because C. antarctica does not demonstrate the two distinct swimming speeds seen in C. limacina, this project focused entirely on C. limacina, henceforth simply referred to as Clione.
