No, crabs do not have teeth in the sense that most people think. They have tooth-like structures in their stomachs in a chamber called the gastric mill which performs food processing, just like the teeth in your mouth. Unlike your teeth, the teeth in a crab's gastric mill are not made of bone, but of a material called chitin, which is the same material that makes up most of a crab's shell.
No.
Atlantic Guitarfish have 56-80 blunt teeth in the upper jaw and 51-82 teeth in the lower. The upper jaw has eight to ten rows of teeth and the lower jaw has seven to nine rows of teeth. The teeth are rectangular at the base and somewhat rounded at the corners, fitting very close together.

Crabeater seals are called crabeater seals because of the way their teeth look.
Yes, barracudas are opportunistic predators and will eat a variety of prey, including crabs. Barracudas have sharp teeth and powerful jaws that allow them to consume a wide range of marine life, including crustaceans like crabs. Their hunting behavior typically involves ambushing their prey, using their speed and agility to catch them.
