Photographers have taken rare photos of a flock of sperm whales, the largest predator on Earth.

The body length of an adult male sperm whale can be up to 20.5m.For males, the body length may be equal to 1/3 of the total body length.So they are also the largest brain animals in the world.(Photo: Barcroft Media)

Sperm fish have a special and difficult body shape that is difficult to confuse with other species.Their heads are large and have a cubic shape.The S-shaped breathing hole is very close to the front of the head and slightly to the left side of the body.This structure makes sperm whale have a very imposing body, especially in front.(Photo: Barcroft Media)

Sperm whales are distributed throughout the oceans and mainly feed on squid - even giant squid species.Sometimes, they also eat other fish.With the ability to dive as deep as 3 km, they are also the deepest diving mammals in the world.(Photo: Barcroft Media)

Female whales often swim into flocks of about 12 animals, including adult females and offspring.Adult males leave the herd when they are 4 to 21 years old.(Photo: Barcroft Media)

The lower jaw of the sperm whale is very narrow and supported from above.They have 18 to 26 teeth on each side of the lower jaw and these teeth fit into the upper jaw.The conical fish teeth and the weight of each can be up to 1kg.(Photo: Barcroft Media)

The sperm whale's brain is the largest of all extant or extinct animals that scientists know, with a mass of up to 8kg.(Photo: Barcroft Media)

The lifespan of sperm whales can be up to 70 years or more.(Photo: Barcroft Media)
