Under the Sea: Extraordinary Things Discovered in the Deepest Parts of the Ocean

Here is another marine worm, but one that isn’t sedentary like the Christmas tree worm. Instead, the squid worm swims free and is named so because he half resembles a squid. His body is a typical tube, like a standard worm, but then he has ten appendages resembling a squid’s tentacles.

Squid worms are mainly scavengers living off what oceanologists call “marine snow.” This organic material falls into the ocean’s depths from water closer to the surface. In another example of how little we’ve explored our oceans, scientists only discovered the squid worm in 2007. Nevertheless, we can understand why they are so hard to spot; they only grow as long as nine centimeters.
