Hey all you people out there! Today I'm talking about bony fish. Yeah, they're the fish that look like Nemo and his friends.
You guys might wonder how fish float so much better than us. Well, they have this thing called a swim bladder. A swim bladder helps fish float around everywhere like a balloon. When it inflates they float up, when it deflates they sink down.
Hey, have you guys ever wondered how fish know when a predator is coming? Well, they have have a thing called a lateral line. They're organs that can sense movement in the surrounding water around them.
Fish breath using gills. Oxygen from the water passes through them and when the oxygen runs out and turns into carbon dioxide, it goes back into the water.
Now let me tell you about the different types of fins like the dorsal fin.
The dorsal is at the back of a fish. There can be up to three of them on one fish. It's used to keep balance in the water.
The caudal fin is the tail fin. It's used to swim away from predators.
The pectoral fin is on each side of a fish near its head.
The anal fin is at the bottom of a fish and is used to stay straight while swimming.
The pelvic fin is on each side of a fish at the bottom and helps it go up or down.
The adipose fin is between the caudal and dorsal fins.
The lateral line on a fish is a sense organ that detects movements in water.
The flying fish actually glides using his pectoral fin by pushing them up. They live in tropical areas and can glide to as high as 160ft.
They can stay in air for 45 seconds and can go up to a distance of 1,300ft. in one glide. They do this to escape from predators or to get somewhere fast.

The American Eel can go up to 6ft. long and live in fresh waters. They also eat dead fish, carrion and insects and can weigh up to 9 pounds.
These fish spawn once a year and stay in groups. They have to jump over things, dodge predators and swim through obstacles to spawn.
Bye all you people.
