480 million years ago, a slug-like ancestor of modern snails and clams had hundreds of tiny teeth, a body covered in prickly spines, and a built-in helmet. Called Calvapilosa, it’s one of the earliest—and weirdest—mollusks ever discovered.
Did a clam just excrete some brown particles in your hand? The good news is that it might not be poop. The bad news is that it might be worse than poop. The best news is that stuff that's "worse than poop" can save an ecosystem.
Let's say you wanted to analyze if the purported brain benefit of flavonoids in chocolate actually did anything. How would you go about it? By teaching snails, of course.
Meet Ctenoides ales, a bivalve that also goes by the names "electric flame scallop" and "fire clam." This invertebrate — which can be found off the coast of the Pacific Rim around Indonesia and Japan — manipulates the highly reflective tissue on its mantle in a wave-like motion, which gives the impression that an…
In The Matrix, the Machines farm humans for energy. Today, we do the exact same thing with tiny critters like cockroaches.
You may know that marine cone snails are some of the most comically toxic creatures on the planet. But have you ever seen one of these mollusks feed? Even though there's no way one of these tiny creatures would be able to devour the human body, watching them chow down makes one prefer the neurotoxins.
If you don't have tickets to Laser Floyd at your neighborhood planetarium tonight, just watch 199 seconds of Metasepia pfefferi — a.k.a. Pfeffer's Flamboyant Cuttlefish — creating its own variegated light show. Some of you may tempted to lick these creatures and pop on some Jethro Tull, but that's not the best idea,…
Not all creatures have soft squishy eyes like us mammals — the mollusks known as chitons have hundreds of primitive visual sensors all over their body, and they're made of a rock called aragonite.
The marine cone nail Conus victoriae is venomous to its prey (and humans), but Australian researchers have isolated a non-addictive, pain-relieving chemical from its saliva. This cyclized peptide, known as α-conotoxin cVc1.1, can be ingested orally in pill form.
Tired of those adorably saccharine puppy and kitten webcam shows? The Hatfield Marine Science Center in Newport, Oregon has set up a streaming camera showcasing their cantankerous 40-pound giant octopus, Deriq. Behold the OctoCam!
After 20 years of studying the sea slug Elysia chlorotica, biologist Sidney Pierce recently discovered a trait unprecedented in the animal kingdom - sea creatures were producing chlorophyll.
