A close-up of a bad shark has never been seen

Mako fish have "dead" black eyes, which help it quickly detect targets.

With a speed of 100km / h and strong teeth, it deserves to be called the most dangerous "killer" in the ocean.

Makako shortfin sharks mature from 2.75 to 4m (9-13 ft) long and can weigh up to 800kg (1,750 pounds), have a light blue back and white belly.

Although both genders grow at the same speed, but sharks (mako fins are short) are thought to have a higher life expectancy and they are also larger and heavier than male sharks.

Shortfin mako sharks are instead spawning, meaning that the offspring grow with ova in a bag within the uterus until they are born.

The pregnancy cycle of mako shark is about 15-18 months.

It is also recognized that the fetuses of mako sharks in the mother's body consume each other for nutrients. This is called cannibalism in the womb.
