Reddish brown coloration can vary with background. 8 suction cup-filled arms are 3-5 times the length of the body. Look for a pile of discarded shells to find the opening to a den.

Flattened and pointed gills. Background color is a translucent grayish white, salmon, or purple.
Small nudibranch with many evenly spaced, slender gills. Vague blue line follows the edges of the foot and down the center of the back. Very small.
Numerous paired, branching gills along its back. Color is highly variable, ranging from white to gray, orange or pink. Feathery cerata are often tipped with orange, yellow, or purple. Large.
Red to purple-black. Abundant, long sharp spines.
Browish-green external covering. Dark tube feet are present around the entire body.
Lavender-gray, red-brown to purple coloration. 5 petal-shaped loops of tube feet on the dorsal surface. Found in soft sediment, standing on end.
