Nightmare fuel from the sea

It is Halloween again, and time for us to dress up and terrify our neighbors! Let’s look at the winners of this year’s spookiest creatures of the deep blue sea!

Second place—Chondrocladia verticillata

What if SpongeBob developed a taste for fresh meat? The answer is Chondrocladia verticillata, a carnivorous sponge that lives on the bottom of the ocean, up to 3,000 meters deep. It preys on small crustaceans and other unfortunate animals, using calcified hook-like spicules to attach to and slowly digest its prey—a grisly fate! So the next time you watch SpongeBob, keep this in mind: Bikini Bottom might not be as friendly a neighborhood as you once imagined.

First place—Terebellidae (spaghetti worms)

Imagine this scene: Long, pale tentacles reach out from a hole on the seafloor waving menacingly in the water, ready to drag you into an unseen creature’s deadly mouth.

This is not the description of a monster from some horror movie. This is a terebellid, or spaghetti worm, a combination of two of the most terrifying things we know: worms and tentacles. But don’t worry, spaghetti worms do not usually grow larger than 3–5 centimeters, they are not venomous, and they mostly eat small particles of floating organic matter. So, they cannot hurt you even if you encounter them while swimming…or can they? Muhahahaha.

Although these creatures send chills up our spines, human over-exploitation of the ocean is the real horror story. If we do not raise awareness about environmental protections and act quickly, our children may only be able to read about these fiends in horror fiction. That is why we at OGL are working to preserve as much information about these fascinating and frightening marine creatures before it is too late.

How our DNA got all marked up

We are all familiar with the genetic code—the simple set of three-letter words that translate the As, Ts, Cs, and Gs of DNA into the diverse and complex forms we know as animal life. But, if every cell in an animal has the same DNA, how does one cell know to become a...

A new paper from OGL solves an old mystery

Shipworms are wormlike wood-eating clams that have been the nemesis of mariners since the first wooden boat set out to sea—and for good reason. Shipworms can gnaw their way through a wooden hull in a matter of months. Since at least 350 BCE, scientists have pondered...

What animal lives more than 250 years but never eats a thing? If you guessed the deep-sea tubeworm Escarpia laminata, you would be correct—and also probably a deep-sea biologist!   Escarpia laminata lives near deep-sea cold seeps, places where methane...

OGL publishes a new paper—about itself!

Have you ever wondered what goes on at the Ocean Genome Legacy Center? If so, you are not alone.   We frequently receive questions such as: Who can use OGL’s collections? What is in them? Where do the samples come from? How do I contact and work with OGL? To answer...
