This majestic fish is classified as “vulnerable” by the International Union for the Conservation of Nature and its Resources (IUCN).

“” “Finding a moon fish in your natural habitat is a privilege that few people can know. And we had the chance to swim with him. We have been able to observe his behavior and learn more about these extraordinary animals ”, said the videographer, accustomed to immortalizing his meetings with marine fauna on his Instagram.

The heaviest bone fish in the world

According to an article in the Monterey Bay Aquarium, a public aquarium in California (United States), moon fish (mole) is able to reach a weight of 2,268 kilograms and can reach three meters long! Difficult to believe that this imposing fish is born from a tiny egg. During his life, his weight will be multiplied by 60 million.

It makes him the heaviest bone fish in the world. It evolves in the tropical and temperate oceans and spends time close to the surface. It feeds on jellyfish because their gelatinous body facilitates its digestion. He has a mucosa similar to mucus in his digestive tract, which protects him from bites.

A fish capable of swimming over long distances despite its large template

Despite its large template, the fish is able to swim over long distances, although slower than other pelagic fish. In the south of California, the moles were seen swimming 26 km per day, at a maximum speed of 3.2 km/h. When it travels, fish can transport with it up to 40 species of parasites!

The fact that this moon fish remains close to the surface makes it vulnerable to fishing nets likely to cut their skin. In addition, plastic pollution in the oceans is also fatal to them. Like turtles, they can confuse a plastic bag with a jellyfish. Plastic can obstruct its stomach, or stifle it when aspired by the mole.
