The Top 7 Fish Facts! | NafiraMadiun

1. Fish are classified as vertebrate animals.
An animal with a spine and bones is known as a vertebrate. Invertebrates, on the other hand, can be found in the sea. A jellyfish and a starfish, for example, both lack a spine.

2. Fish are quick!
Fish can swim quite quickly. Sailfish, marlin, and tuna are among the quickest. A sailfish can reach speeds of up to 68 miles per hour. A marlin can swim at speeds of up to 50 miles per hour, whereas a tuna can reach speeds of up to 47 miles per hour.

3. Fish need their gills to breathe.
Fish breathe through their gills. They are frequently discovered on the side of their bodies. Their gills are responsible for collecting oxygen from the water.

4. The majority of fish lack eyelids.
Imagine not being able to blink while swimming in the water. A shark is the only fish that can blink.

5. Fish have a cold blooded nature!
The majority of fish are cold-blooded, whereas we are warm-blooded. However, there is one exception... Tuna and mackerel sharks, like us, have warm blood. Warm blood is also found in Opah fish.

6. Fish scales aid in swimming.
Scales are extremely beneficial to fish. They're slimy, which makes it easier for them to slide through water.

7. Some of the fish are enormous!
A whale shark is the world's largest fish. It can grow up to 12 meters in length and weigh up to 18.7 tons. That's the equivalent of a double-decker bus!
