Thylacodes variabilis is a species of worm snail common in the rocky intertidal in Hawaiʻi and the tropical Pacific.[1]

Thylacodes variabilis reaches a length of 14 millimeters at the most.[2] Female Thylacodes variabilis release their offspring via eggs/capsules. There are 48 capsules per female and 240 eggs per capsule.[3] Thylacodes variabilis resides down to depths of 40 feet. The snail lives in open environments, to include: tide pools, shallow, wave-swept reef flats, and rocky reefs. The snail has a white-brown shell, which is coiled or partly straight. The shell is often overgrown with coralline algae or coated with sand grains. This is the only worm snail in Hawaii that has no operculum.[4]
