The Swimming Circuit in the Pteropod Mollusk Clione limacina
The pelagic marine mollusk Clione limacina (class Gastropoda, subclass Opisthobranchaea, order Pteropoda), 3–5 cm in length, swims by rhythmically moving (1–2-Hz) two winglike appendages. Each swim cycle consists of two phases—the dorsal (D) and ventral (V) wing flexions. The nervous system of Clion...
