Later on we will probably find out this is the baby worm, and that the mom and dad worms eat divers.

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, its actually perfectly safe to approach. Pyrosomes are part of a family of sea creatures known as tunicates or sea squirts. Theyve also been called cockroaches of the sea, National Geographic notes, due to their ability to pull food from even the most inhospitable environments.
Buttle told National Geographic that swimming next to it the pyrosome was pretty incredible. He also noted how they could see thousands of tiny creatures along the giant sea worms body, up close.
Thats because pyrosomes are actually a free-flowing colony of hundreds or even thousands of individual organisms. These organisms are known as zooids. The small multicellular creatures pump water through their bodies to catch and feed on phytoplankton, poop particles, and other bacteria.
Andrew Jeffs, a marine science professor at the University of Auckland says that the pyrosome and the salp, a cousin of the pyrosome, are both important to tropical waters as a food source. Other creatures like turtles and spiny lobsters cling to the tubes and can feed for weeks at a time.
At night, pyrosomes swim to the surface of the sea. There they feed on whatever they can find in the water. Their bodies are very similar to gelatinous organisms like jellyfish. Additionally, they glow due to natural bioluminescence. While this one was 26-foot long, they can be as small as one centimeter in size. As long as the entire colony isnt wiped out, they can theoretically live on forever.
Sightings of these giant sea worms are rare. But, scientists are making more efforts to study and understand these creatures.
