What do sharks look like?
Most sharks have long, narrow bodies to help them swim quickly through the water. A shark’s nose is often referred to as a snout. Most snouts are long and pointy.
A shark can have as many as 7 fins and a tail.
A shark’s fins are very important for the shark to survive. Shark fins help keep the shark balance in the water. Without fins, sharks would not be able to stay upright in the water. They would roll over and be belly up!
Shark fins help the shark change the direction they are swimming in, they also help the shark to slow down.
Probably the most known or popular shark fin is the dorsal fin. Most sharks have two dorsal fins. The first dorsal fin is the one commonly associated with sharks- it sticks out of the water. It is located on the top of the sharks back. The second dorsal fin is located further down the sharks back and is smaller in size.
Sharks have several more fins on their bodies. Some are located on the sides of the shark near the front of their body and some are on the bottom of the shark, near its tail.
Sharks do not have scales like other fish. Shark’s skin is made up of denticles. The word denticles mean “little tooth.” They make then shark’s skin feel like sandpaper. It is very rough.
Some species of shark have more than one row of teeth, their teeth like human teeth fall out. Sometimes shark teeth will wash up onshore.
Some species of shark will go through 30,000 teeth in one lifetime.
Most shark teeth are very sharp.
How do sharks breathe underwater? Sharks need oxygen to survive, just like humans. Sharks breathe differently from humans. Sharks use their gills to take in oxygen from the water. Most sharks have 5 gills on either side of their bodies.
