Divers discovered a horrifying 26-foot sea worm that only comes out at night

Divers off the coast of New Zealand came face to face with a giant sea worm that was almost 30-foot long.

The creature is called a pyrosome, and while it might look intimidating, it’s actually perfectly safe to approach. Pyrosomes are part of a family of sea creatures known as tunicates or “sea squirts”. They’ve also been called cockroaches of the sea, National Geographic notes, due to their ability to pull food from even the most inhospitable environments.
