There are eight animals that resemble private parts, including the proboscis monkey, Sicilian worm, razor clam, acorn worm, gooey duck clam, Hoosier cavefish, priapulids, and spoon worm.

Highlights

1 The proboscis monkey has a fleshy, bulbous nose that is used to attract mates.

2 The Sicilian worm is an amphibian with venomous, needle-sharp teeth.

3 The razor clam got its name because it resembles the old-school razors used by barbers.

4 The acorn worm is known for its acorn-shaped front end and is our closest invertebrate relative.

5 The gooey duck clam is a prized delicacy that resembles a phallus.

6 The Hoosier cavefish has its anus right behind its head.

7 The priapulids, or penis worms, are named after the Greek god Priapus, the god of fertility.

8 The spoon worm is commonly referred to as an innkeeper worm due to its U-shaped burrows made in the sand.
