It is called the ghost fish because it looks more fierce, like a terrible devil. What's more, it likes to swim to the bottom of the boat and beat the bottom of the boat with the wings of its body, making a "whirr and snap" sound, which makes the people on the boat panic.

Sometimes he would run to a boat moored in the sea, hang his horn on the chain, and pull up the little iron anchor, much to the horror of the people in the boat.

Manta rays mainly inhabit shallow waters in the tropics and subtropics, but rarely stay or inhabit the seafloor. They can be seen from the surface layer of water close to the shore up to 120 meters deep.

Manta rays look scary, but without upsetting them, they're actually quite gentle.

Although they have a large body, their mouth is small and their teeth are not well developed, so they can only eat small fish, shrimp and shellfish, unlike sharks, which can kill people.

Its size and strength often scare divers, because if it gets angry, with just a flap of its powerful "wings," it can break bones and kill a human. That's why they call it "ghost fish."

The manta also has a tail fin like a riding whip, and the root is connected to the fish's body by a thorn, which is serrated, extremely sharp and can secrete venom.

If you accidentally touch it, the wound will become inflamed and painful.

Manta rays can easily grow to more than six metres across, and they swim gracefully. Because of their size, manta rays are like mobile restaurants for parasites and often need to stay in the water layer for cleaner fish to remove them.

Some say manta rays jump to the surface to remove dead skin and parasites. The manta rises through the ocean in a rotational motion, increasing its speed and speed as it approaches the surface until it leaps out of the water, sometimes with a nice flip.

At its highest, it can jump 1.5 to 2 meters high and when it falls into the water, it makes a loud noise, which is a beautiful and spectacular scene.

Manta rays are ovoviviparous, giving birth to only one litter at a time, and females are very protective of their only offspring.

The gentle fish also have a high IQ, and a manta ray approaches a diver to show off a hook under its eye off the Ningaloo coast in Western Australia.

It returned to the diver several times, making it clear that it needed help, before the diver finally removed the hook.
