Project Description

During a wall dive I noticed a grunt sculpin (Rhamphocottus richardsonii) inside a boot sponge taking a look as I approached its home.  This small fish looks amazing with its large head and small body, especially when it “hops” along the bottom on its pectoral fin rays.  The grunt sculpin grows to about 3.5 inches (8.9 cm) long with a range that includes Japan, and central Alaska to southern California.
