What is the egg yolk-like substance in the shark's stomach?

Shark eggs. Oviparous sharks lay eggs with thick egg sheaths. The egg sheaths protect the fertilized eggs. The yolk sac inside provides nutrients for the fertilized eggs to grow. There are usually some attachment threads around the egg sheaths, which enable them to attach to rocks or seaweed and resist predators. Generally, large sharks use this method. Shark eggs are large and have no shortage of nutrients.

How many teeth does a shark replace in its lifetime?

Sharks can replace more than 35,000 teeth in their lifetime. The tooth arrangement of sharks is quite special. In the back row of teeth on the outside, there are usually 4 to 6 rows of "spare teeth". If the first row of teeth fall off or are damaged, the back row of teeth can be immediately moved forward to replace them.

Will a shark die if its fins are cut off?

They will bleed to death. Usually the fins of great white sharks are cut. Because great white sharks are the largest and most ferocious and are at the top of the ocean food chain, they will be eaten by other fish only after they die. If it is another shark or other injured fish, they will be eaten alive.
