What is a crocodile shark?

Mackerel sharks are a group of fish characterized by anal fins, two dorsal fins, five slits and eyes behind the eyes. Crocodile shark is a type of small shark mackerel that lives in the oceans around the world. It is a predator, dining mainly on smaller fish, octopus and shrimp. This shark is sometimes referred to as a water crocodile, a Japanese shark of a ragged tooth or Kamohrin sandy shark. Its parties sometimes seem flat when viewed from the front. This fish can have a slightly rounded belly and jaw. Directions cover the sides of this animal, which means they may seem shiny. Belly and head are usually boring. The tanges of this animal often have black tags on the tip of black brands and one or both dorsal fin is silver. Floor (1 m) long when they are fully mature. The adult crocodile shark usually weighs between nine and £ 13 (4 to 6 kg). This fish does not contain much meat, so it is rarely stored whenever it is caught.

Eyes of the crocodile shark are green or yellow with a slightly reflective cover. This covering makes this fish easier at night. It is assumed that this shark can detect the silhouette of its prey, although only very small light penetrates into the water. As such, it is a night animal that remains in deeper water during the day and swims in more shallow water at night.

The upper and lower jaw of the crocodile shark has several rows of teeth. These teeth are aimed at the end and serrated around the edges. Each line contains up to 30 teeth. Like other types of shark, crocodile shark will never get out of teeth. When one is lost, the new one spring forward to lead the place that is released.

The common places where the crocodile shark can be found include the Atlantic coast of South America, the Indian Ocean and the Pacific coast of Tai -Wan and Korea.
