Why is a shark not a fish?

Are sharks fish? Sharks are fish. They live in water, and use their gills to filter oxygen from the water. Sharks are a special type of fish known because their body is made out of cartilage instead of bones like other fish.

What fish don't lay eggs?

Do all fish lay eggs?

The methods of reproduction in fishes are varied, but most fishes lay a large number of small eggs, fertilized and scattered outside of the body. The eggs of pelagic fishes usually remain suspended in the open water. Many shore and freshwater fishes lay eggs on the bottom or among plants.

Do sharks have tongues?

Sharks do have tongues, but they are not like the tongues of humans or other mammals. Sharks belong to a group of animals known as cartilaginous fish, which also includes rays and skates. Unlike mammals, which have bones, cartilaginous fish have skeletons made of cartilage, a type of flexible connective tissue.

How do sharks impregnate?

How often do sharks have sex? As often as possible. Unlike swans, who mate for life, shark sex “happens when it happens,” Burgess says. “It's like 1 o'clock in the morning, and the bar's closing.” Male sharks can sniff out ovulating females, who give off pheromones (chemical signals) when they're ready for mating.
