This sea hare is just about impossible to see when it is snuggled into the branches of eelgrass or zostera. Its camouflage is obvious and it is most commonly known as the Eelgrass Sea Hare.  It grazes on diatomes and other epiphytes found on the green leaves and lays its tiny eggs in a zigzag pattern on its host.  For more discussion and photos of this sea slug, see Bob Rudham’s Sea Slug Forum.
