Shark Cam or Lunch?

You do not need to swim with the sharks ... unless planning to go to sea in a leaky boat.
And yes, I did feel sorry for the shark in the video with the broken away teeth ... then I read the following from Wikipedia. Now, if only we could cross the shark teeth regrowing capability with say .... money .... well, that would be good. Maybe the blue-green algae in Ohio (see other recent CR4 Discussion subject) already know the (engineering) secrets.

"Sharks come in many different shapes and sizes, but most are long and thin (also called streamlined), with powerful jaws. Their teeth are constantly replaced throughout their lives. Sharks eat so violently they often break a few teeth, so new teeth grow continuously in a groove just inside the mouth and move forward from inside the mouth on "conveyor belts" formed by the skin in which they are attached to. In its lifetime, a shark can lose and regrow as many as 30,000 teeth.

Even with all those teeth, though, sharks can not chew. So they bite their prey and jerk it around so they can pull of a chunk to swallow. The chunks of food that a shark swallows ends up in its stomach, where they are digested. This is pretty slow, however, so a meal might take several days to digest. This is why a shark does not eat every day.

Sharks have different-shaped teeth, depending on what they eat. For instance, some sharks have sharp, pointy teeth, while bottom dwelling sharks have cone-shaped teeth for crushing shells. Because there are so many different kinds of sharks, and because each kind has its own kind of special teeth, many people enjoy collecting shark teeth. Shark teeth collectors can guess how large a shark was by measuring the shark tooth! First, they measure the length of the tooth in inches. Every inch of tooth equals 10ft of shark length: so if a shark tooth is 2 inches long, the tooth came from a shark that was 20 ft long! Even more terrifying is that some of the Megalodon teeth are 6 inches long so that suggets a shark 60 feet long.

Sharks have skin covered in millions of tiny teeth-like scales that point to the tail. If you rub along a shark towards the tail, it would feel smooth, but if you rub the other way, it would be rough. Sharks' teeth can be 20 times as big as human teeth and they can grow back if they are lost."
