It is often thought that weird cartoony animals are a thing of the past. Nevertheless, hammerhead sharks show us that evolution will never end. What seems illogical or even detrimental to an animal's survival can be the key to them thriving in a specific environment. The following discussion will include the general life of the hammerhead, the anatomy of the hammerhead, and the future of the hammerhead. The General Life of a Hammerhead How it all started Sharks have existed for about 450 million years, outliving almost all types of animals (Davis, Josh). Hammerheads date back only 23 million years and are thought to be the youngest shark group to have evolved so far. There are at least eight different species of …show more content…
They can be up to 6m (19.6 ft) and 450kg (992.08 lbs). They can also live 20 to 30 years on average. Communication Hammerheads are often seen in mass summer migrations seeking cooler water. A school of scalloped hammerheads may have 100 to 500 specimens; however, the majority of hammerheads in a school are female (Davis, Skip). For communication, hammerheads use body language to establish the social hierarchy and give orders for the schools to disperse. Examples of body language include head shakes, torso thrusts, and swimming in loops. The Anatomy of the Hammerhead Predatory Vision The visual field is the expanse of space visible to an organism without the movement of the eyes. Biological Sciences, Florida Atlantic University, Boca Raton, FL 33431, USA. On average, the horizontal binocular FOV of humans is 200 degrees out of which 120 degrees is a binocular overlap (Kore). While comparing the FOVs of three hammerhead shark species to two other typical shark species, the horizontal visual views ranged from 308° to 340°, with the hammerheads on the upper end of the spectrum. When comparing the binocular field of view, hammerheads had a max of 48° in

The protection of the great hammerhead does matter because of its role as an apex predator, its act of mixing nutrients within the ocean levels, and the ensuing effects if we were to lose them altogether. Shark-finning is the process of removing the shark’s lateral, dorsal, and lower tail fins, and is generally followed by releasing the alive shark back into the ocean, where it can no longer survive, and dies. (Rafferty, John P.) The great hammerhead shark is harvested worldwide for its large fins…

Sphyrna mokarran Sphyrna mokarran, the Great Hammerhead Shark, is a Chronodrichtyes, a cartilaginous fish in taxonomic species term. The skeletal structure of hammerheads is made of hard cartilage rather than bone. Furthermore, the hammerhead shark is found in the Chordata phylum and is a part of the Vertebrata sub-phylum, therefore they have a notochord, spinal cord, and backbone; a notochord is a long, flexible rod that runs down the longitudinal part of the body and is made out of cells in a tough…

Female Hammerhead Sharks Research Paper

Hammerhead sharks have the fastest mating rate than other types of sharks. The cubs stay in the mother’s stomach for months and usually are born at separate times same time. The female gives birth to live young cubs. When the female mother is pregnant it needs to have a healthy diet so the cubs inside get all the protein they need. Female hammerhead sharks can be pregnant without mating and tests have been proven. There isn’t an exact theory of how they can get pregnant without mating, but female…
