Project Description

It was great finding this cluster of tennis ball sponges (Craniella villosa) during a boat dive near Campbell River, Vancouver Island.  There was some current during the dive and this is the environment where these sponges prefer to live, areas with fast water flow.  This sponge has the appearance of a tennis ball but is much larger with very large sponges reaching 10 inches (25 cm) in diameter.  The tennis ball sponge likes exposed rocky areas, and has a range from northern Alaska to northern Mexico.
