Hermit crabs often share their shells with smaller critters. A two-tentacled worm lives with this Hairy hermit; it waves its tentacles out of a hole at the rear of the shell. A mobile base gives the worm access to more food. Does it tickle? The hermit doesn't seem to mind. #VancouverIsland #HermitCrabs #IntertidalInvertebrates #Invertebrates #MarineLife #DailyHermit
