It might become your new favorite after all! Listed below are some things you should know about the hammerhead shark.
Hammerhead Sharks Are The Largest
A hammerhead shark has a peculiarly shaped head, which has led to many theories regarding how the fish evolved.
While some scientists believe the shape evolved gradually over many generations, others believe it was a sudden mutation.
It is thought that a hammer-shaped head was beneficial to the shark as it would provide a larger surface area for sensors, making the animal more sensitive when scanning for food.
The Great Hammerhead shark is the largest of all hammerheads, with a length of up to 11 feet and a weight of 500 pounds. Its first dorsal fin is also very tall and falcate.
The Great Hammerhead’s lifespan is 20-30 years, although it has been known to grow to 20 feet. Most hammerhead sharks grow to be between 10 and 14 feet long.
They can grow up to twenty feet long, but the biggest one was caught in Florida in 2006.
These sharks have a life span of 20 to 30 years, though their largest specimens are between 10 and 14 feet in length.
Their population is considered to be threatened and endangered. Great hammerheads are circumtropical, and range from North Carolina to Uruguay.
They also inhabit the Gulf of Mexico, French Polynesia, and southern Baja California.
Under the 1982 Convention on the Law of the Sea, the Great Hammerhead is classified as a “highly migratory species”.
They Have A Large Hammerhead
The hammerhead shark is a species of saber-toothed shark that can grow to be about eighteen feet long, weighing between three and five hundred pounds.
Its body is colored light green with a greenish tint and is usually found in shallow water.
Adult males can grow to be around twenty feet long, while juveniles are shorter and thinner.
They are commonly found in shallow water, but can occasionally be found up to 300 feet deep.
Their bodies are shaped like a hammer and are characterized by flat, rounded lobes with eyes and nostrils located on the side.
Although they are relatively rare, they are very popular as food. This is partly because they are not as aggressive as other species of sharks.
In addition to their large hammers, these sharks have a large placenta. A mother hammerhead has six to eighty pups and can produce more than fifty in a litter.
Hammerheads are typically found in coastal areas, but they are also known to migrate thousands of kilometers into the open ocean.
While the name of this shark comes from the Greek word “Sphyrna,” this species is also known as the scalloped hammerhead.
These sharks have a flat, hammer-shaped head with a center notch, and they live in tropical and temperate waters.
Young hammerheads inhabit estuarine areas around Fiji and are known to frequent the waters surrounding the island nation.
Although this species is vulnerable throughout its worldwide range, recent discoveries have highlighted the importance of finding areas for aggregation to ensure its survival.
They Have 7 Senses
The seven senses of the Hammerhead Shark make them a highly intelligent predator.
They can detect human blood from several miles away and use these sensors to identify their prey.
Each of the seven senses has a special role in hunting and defending the ecosystem. To learn more, read on to discover how these sharks use their senses.
Let’s start with the lateral line. These tubes run under the shark’s skin and are lined with sensory cells.
When something comes near, the water flows back and forth, stimulating these cells.
Their nose and eyes are located on the head’s extension. They also have large, olfactory rosettes.
These sharks have true stereo-olfaction, which means that they can compare odors and orient themselves toward them.
This sensory system helps them detect one part of every 25 million of the blood in seawater. They can even smell the scent of prey as close as 20 feet away.
A shark’s nose is remarkably sensitive. It can detect a drop of blood in an Olympic-sized pool. Its acute olfactory system can also tell when its prey is afraid or wounded.
It also has a keen sense of hearing. While sharks don’t have ears, they have tiny openings on the sides of their heads that serve as a sensory system.
This helps them to determine the location of prey that may be near.
They Hunt Alone
Although most sharks are solitary, the Great and Scalloped Hammerheads sometimes swim in schools.
Schooling can benefit the sharks’ hunting strategy by allowing them to hunt bigger and more difficult prey.
Schooling can also help the females stay safe, as the females choose which males they want to swim with.
The females usually stay at the top of the school, while the males are found deeper in the ocean.
This species of shark lives in temperate and tropical oceans, preferably in shallower waters.
It is buoyant and has wide eyes and nostrils, which helps it stick to the ocean floor. While hammerhead sharks are often solitary hunters, they can be seen in packs of up to 100 sharks.
They are known to hunt at night, during the day they hunt with their partners in a pack.
The name “Hammerhead” refers to the shape of the hammerhead shark’s head.
While all sharks have electroreceptors, the hammerhead’s long head contains more receptors than any other shark.
Hammerheads typically hunt alone and feed on stingrays, but they will also eat other sharks and bony fish. When they are hunting, they are often alone.
They Are Vulnerable To Artisanal Fisheries
The hammerhead shark, or hammerheads for short, is the smallest and most threatened shark species in the world, with only nine described species and two genera.
They inhabit the oceans near continental shelves and are subject to extensive overfishing and habitat loss.
In addition, hammerhead sharks are among the most commonly fished species.
The eradication of artisanal fisheries and the development of alternative methods of catching and processing hammerhead sharks could save the hammerhead shark.
Overfishing is a major threat to hammerhead shark populations, and artisanal fishermen have been documented to target juvenile and immature hammerheads for elasmobranchs.
They have also been caught in gillnets, which heavily target scalloped hammerheads, which are considered a high-demand catch.
This artisanal fishery has been a serious issue for hammerheads, as the exploitation of scalloped hammerheads has been linked to a deterioration in the population.
In the last decade, hammerhead sharks have become more than just a source of high-quality meat.
In addition, some commercial fishers have taken to shark finning on the open ocean, where their catch was more valuable than their bodies.
This has sparked concerns about the continued destruction of this species and other fisheries.
Furthermore, scalloped hammerhead sharks are migratory and migrate significant distances, making their populations more vulnerable to artisanal fishing.
They Are Endangered
The great hammerhead shark’s population has decreased significantly in all oceans.
In the Mediterranean and Indian Oceans, their numbers have almost dwindled to extinction. And the Atlantic has seen a 50% decrease in the last 70 years.
This dramatic decline is due to overfishing. Although studies have shown that specific species are suffering regional declines, no one has compiled trends for all oceans.
The loss of these majestic creatures would lead to catastrophic changes to the ecology of the seas.
In addition to reducing fishing mortality, hammerhead sharks are also endangered.
Research shows that the reproductive migration of the hammerhead shark is crucial for implementing conservation plans in the region.
For example, for a female hammerhead shark to give birth to 20 to 30 baby sharks, it must swim approximately seven hundred and thirty kilometers (435 miles) to reach the continental coast, where it will give birth to its first offspring.
Along the way, the mother hammerhead must avoid thousands of fishing hooks and nets. Great hammerheads are the largest of the three hammerhead species.
These creatures can reach lengths of up to six meters. They are solitary swimmers that live in tropical seas. They tend to live in coastal regions but are also seen far offshore.
Hammerheads play an essential role in maintaining the diversity and stability of ocean bio-communities, so their extinction may severely impact ecosystem stability.
