Project Description

It was interesting to see this swimming winged sea slug with its wings fully extended.  This small animal (Gastropteron pacificum) was a rare find for me and spotted at Nanoose Bay.  The winged sea slug is a strong swimmer, and its wings (parapodia) are extensions of its foot.  The winged sea slug grows to only 1.6 inches (4 cm) long, with a range from northern Alaska to northern Mexico, as well as the Galapagos Islands.
