Is a Shark a Mammal or Fish?

That is the question that is perhaps most commonly asked when talking about sharks. Since sharks give birth to pups, and a few species lay eggs, the common consensus is that sharks are mammals.

Are Sharks Fish?

Mammals

Mammals are warn-blooded creatures that are identified by giving birth to live kids, being covered in hair, and feeding their offspring via milk from mammary glands.

Fish

Fish are aquatic creatures that are mostly cold-blood. Most have scales, breathe through gills, and come with two sets of fins, some of which are paired, while others are not.

Where do Sharks Fit in to All This?

How do Sharks Breathe?

Mammals and fish are equipped with totally different breathing mechanisms. Sea mammals such as dolphins and whales rely on a blowhole to draw air into their lungs. These mammals periodically need to break the surface of the ocean to draw in that air.

Between those moments, they keep their blowholes closes to prevent water from seeping into their lungs. Fish can stay underwater at all times, using their gills to breathe in and out.

Fish take water in through the mouth and pass it out through the gills. Sharks are not equipped with lungs, but they do have anywhere from 5 to 7 gill openings to help them breathe underwater.

Skin

Mammals and fish are also separated by the way in which their skin feels and operates. Warm-blooded mammals have smooth skin that remains that way because their bodies are able to regulate temperature because of that blood flow and temperature.

The skin that covers fish cannot be kept warm that way, and can be adversely affected by the temperature of the water that they are swimming in.

While the skin of a shark may appear to be smooth, it is actually made up of toothy scales known as dermal denticles. These jagged scales prevent the skin from parasitic damage, whilst also helping the shark move through the water quickly.

Dorsal Fin

Sea mammals come equipped with a single dorsal fin, or sometimes none at all. Fish, on the other hand, have more than one dorsal fin, and are usually equipped with several in different parts of the body, with each one serving a specific purpose, such as steering or stabilizing.

The fins that a shark have help them move forward at speed, but are unable to allow them to move backwards or sideways. If a shark want to get past an object, it allows its body to drift away from it.

As you should be beginning to see by now, there are definite looks and traits that clearly identify a shark as a fish.

The reason that we need to rely on teeth for information is because sharks have no bones, therefore making it impossible for fossils to be discovered.
