Eel-like pearlfish uses a lumbering sea cucumber to hide in grossest way

Aquatic life is full of strange and fascinating creatures, but it’s also full of some gross-looking weirdos. The sea cucumber, for lack of a better term, is essentially a hulking, worm-like colon. What it takes in one end, it…gets rid of from the other. The slinking seasnake pearlfish uses this particular adaptation to its advantage and hides inside the cucumber when it senses danger.
