Sea cucumber

Sea cucumber

Sea cucumbers spit out their guts via their anus as a defense mechanism. Also since pearlfish has no defense mechanism of their own, they hide from predators by burrowing into a sea cucumber's anus. While inside, it may eat the cucumber's gonads. Although the cucumber normally defends itself by squirting out its guts, the pearlfish does not trigger this response, possibly because it isn't worth the trouble.
