Fossils of the world’s largest ammonites can be found on either side of the Atlantic. About 80 million years ago, human-size sea creatures with tentacle-like arms and coiled shells up to 6 feet (1.8 meters) wide glided through the Atlantic Ocean, a new study reveals.

Cats create “mental maps” using audio cues, scientists have discovered. Your cat is probably keeping track of where you are, even if your feline friend isn’t in the same room with you and can’t see you. Scientists recently learned that domestic cats create “mental maps” that tell them where nearbyContinue Reading
Fish keep their friends close and their enemies closer Fish keep their friends close and their enemies closer … but only because they need to exfoliate.

Great white sharks’ vision may lead to mistaken identity. Great white sharks can’t see the difference between their typical prey and humans swimming or paddling on surfboards, suggesting some shark attacks are cases of mistaken identity, according to a new study. Researchers filmed seals and humans in water and editedContinue Reading

The team wasn’t expecting to see a shipwreck … or a squid. Scientists mapping the seafloor in the Gulf of Aqaba, the “right antenna” part of the northern Red Sea, recently made two remarkable sightings almost simultaneously: a sunken shipwreck and a mysterious big squid zipping around it, according toContinue Reading
The sea scorpion was the apex predator of its time. A 3.3 foot-long (1 meter) sea scorpion prowled the seas of what is now China some 435 million years ago, using its giant, spiny arms to ensnare prey. Palaeontologists recently discovered the remains of this scorpion (Terropterus xiushanensis), which wasContinue Reading
