An analysis of fossil jaws belonging to octopuses that lived between 100 million and 72 million years ago shows that these creatures may have been the largest animals in the sea and smart to boot, rivaling sharks and marine reptiles in their powers of predation.

They have a very thick round shell. They are distinctive and look like a full moon. The rest of the animal is fleshyhas a huge muscular foot and can propel itself to glide along the sea floor. While hunting on the seafloor, she added, It has a special structure on the front that acts like a snow plow. But the moon snail is a sand plow, so you'll see it push sand out of the way and sniff out chemical cues from their food.

Jaws taps a primal fear: predation. We like to think of ourselves as separate and above the rest of the animal kingdom, but movies like Jaws remind us of something else: Sometimes, human beings can be lunch.
