Sharks
The one I have , has 26 teeth, in front, but like a shark there are teeth in rows behind the front ones, so the exact number would vary from fish to fish.
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.
Lampreys have rows of small, sharp teeth on their tongues and sucker-like mouths which they use to attach themselves to the fish. They then rasp away the flesh of the fish using their teeth and feed on the blood and bodily fluids.
Pythons have 4 rows of teeth on the top and 2 rows of teeth on the bottom. Pythons do not have fangs.
Sharks have rows upon rows of teeth in their mouth and when the teeth fall out the new row of teeth is ready to come through.
True, they are! There are several rows of teeth that regenerate over the course of the shark's lifetime.

Sharks have multiple rows of teeth arranged in several layers. They continuously shed and replace their teeth throughout their lifetime, with some species capable of producing thousands of teeth in a year.
Piranhas have just a single row of triangular teeth on both the upper and lower jaws. Their close relatives, the pacu, have two rows of square teeth.
Sharks aren't venomous. They are simply dangerous because they are large and they have many rows of sharp teeth.
A bull shark can have up to fifty rows of teeth. When teeth fall out, they are replaced with new ones, similar to how humans lose their baby teeth.
