Researchers have spotted an atypical gathering of rare prickly sharks around a seamount off Panama.

The blue dragon may be too weak to resist the ocean's current, but it can take on a Portuguese man o'war and even steal its venom.

Scientists discovered this little panda skeleton that lives off the coast of a Japanese island was a new species after scuba divers posted photos of it online.

Disturbing footage shows the moment a single orca chased down a great white shark and killed it, then swam away with the shark's liver in its jaws.

Climate change appears to be causing North Atlantic right whales to get smaller, and it's making them have fewer babies.

Two new ancient shark species have been uncovered in Mammoth Cave with teeth that "look like they just came out of the shark's mouth yesterday."

A newborn great white shark has been seen in the wild for the first time, and the discovery could help scientists finally solve a longstanding mystery about the threatened species.

Scientists have discovered a new species, related to the roly poly bug, that plays an important role in keeping the ocean healthy.

Bottlenose dolphins have been observed trying to kill Antillean manatee calves, and researchers don't fully understand what's going on.

Scientists say they have discovered a discrepancy in previous research and suggest megalodons may have been longer and more slender than previously believed — but not everyone is convinced.

Catch data from 2012 to 2019 reveal shark deaths from fishing increased from 76 million to 80 million per year. Researchers stress that more action is needed to save threatened species.
