Mysterious Sea Creature

A mysterious, decaying marine creature washed up on a beach in Papua New Guinea. Experts believe it's a marine mammal, but can't identify it.

A video of a transparent sea creature caught by a fisherman has been grabbing eyeballs on the Internet.

A shark graveyard, full of fossilized teeth, some millions of years old, has been discovered on the sea floor of the remote Western Australian coast.

The unknown animal's body was discovered on the shores of Barna Pier in Galway, Ireland, on November 12, making internet users wonder what it was.

An Australian fisherman recently left social media users baffled by his unlikely catch of a mysterious deep-sea shark with protruding teeth and large eyes.

As per the video posted by NOAA on Twitter, marine scientists have seen these creatures several times during expedition.

One Reddit user said the creature looks like pipefish, an explanation accepted by the person who posted the photo.

The 47-second-long clip shows the creature repeatedly leaping out of water

National parks officials in North Carolinahave shared a photograph of a mysterious blob that they have failed to identify. "Beach mystery -- Do you know what this mysterious mass is?" they asked on Facebook.

A beachgoer came across a decidedly rare sight while out for a morning stroll on California's Newport Beach on Friday. Ben Estes spotted a Pacific Footballfish on the beach.

A mysterious sea creature stretching more than 23-feet has washed up on a beach in Wales.

A mysterious 15-foot creature has been found washed up on a British beach, leaving locals stunned.

For fish inhabiting the immense darkness of the deep sea, being ultra-black offers great camouflage in a fish-eat-fish world. Scientists studying some of these exotic creatures now have unraveled the secret behind their extreme color.

Pictures of a fish with bizarrely human-like features are going viral on social media. Found and photographed in Malaysian waters, the fish in the viral pics has teeth and lips that look strangely human.

The video begins with a fin protruding out of water - a sight that would make anyone think of a shark. But it wasn't a shark that this fishing group encountered off the coast of Wales, it was something else entirely.
