The hammerhead shark (Sphyrna zygaena) is part of the family Sphyrnidae, the order Carcharhiniformes. It can be found in tropical and subtropical waters, more precisely in temperate waters around the world.
The first species of hammerhead shark was described by Carl Linnaeus in 1758, and the newest species was discovered in 2013. At the time the article appeared, there are nine species of hammer sharks.
Some species have come to the forefront of the authorities because their numbers are decreasing and will soon be put at risk of extinction. And today fishermen catch hammerhead sharks in their nets and meat is sold in stores.
Some parts are searched for food purposes. In order not to encourage trade, I will not make these parts public. Sharks, along with other marine animals, are sanitary oceans.
Hammerhead Shark’s Food
The hammerhead shark feeds on sea cats, different species of other smaller sharks, fish, snakes, crustaceans, etc.
The favorite food for hammerhead shark is the sea eagle (it is a species similar to sea cats).
After killing the prey, it somehow fixes it on the ocean floor and starts to consume it.
Hammerhead Shark’s Aspect
The hammerhead shark has a length of 4-5 meters and a weight of 200-400kg. The mouth is endowed with approximately 60 teeth. The body is dark gray or gray-brown on the back, and the belly and the lower parts are whitish. On the side you can see the 5 gills positioned symmetrically on one side of the body.
The hammerhead shark can be easily identified by the shape of the head like a hammer. The eyes are positioned at the extremity giving them both a great advantage and a great disadvantage. The advantage is that it has very good vision, even binoculars and can’t see 360 degrees.
These sharks see on the side, below and above and can even estimate the depth pretty well. The disadvantage is that the eyes are exposed to predators and may lose sight quite easily. Nobody knows why the hammerhead shark has evolved. Biologists issue hypotheses to better identify prey or help it float better.
There are about 10 species of hammerhead sharks in the world. The most cave species of hammerhead shark is Shiny Shark Head with Hammerhead. Certain parts of the hammerhead shark were considered a culinary delicacy.
Hammerhead Shark’s Behavior
The hammerhead shark sinks to a depth of 400 meters. It is often seen on the surface, the dorsal swing can be easily seen.
It is a migratory species that moves in banks to make it easier to attack other sharks or predators. He has few natural predators. Banks are made up of 50 to 500 individuals.
This proves to be sociable. The group usually follows a routine and sets themselves up in places where food is as accessible as possible.
He has an unpredictable temper and is considered aggressive if you enter his territory. Many consider bizarre this over because of both shape and behavior.
Hammerhead Shark’s Reproduction
The hammerhead shark, like the big white shark, is giving birth to live sharks. It is a viviparous species in which little sharks develop within the female.
The female gives birth to 15-40 baby sharks after a gestation of 10-11 months.
Sexual maturity is reached after it exceeds 2 meters.
The life expectancy of hammerhead shark is over 20 years.
