bonnetheads

Bonnetheads are a species of sharks that belong to the genus Sphyrna. They are a type of hammerhead shark that is characterized by their distinctive head shape, which is laterally extended to form a U-shaped fin. This adaptation is thought to provide improved vision and movement capabilities.

There are three species of bonnethead sharks: Sphyrna tiburo, Sphyrna mokarran, and Sphyrna zygaena. The most common species, Sphyrna tiburo, is found in the Atlantic, Pacific, and Indian Oceans, and is commonly encountered in shallow, tropical waters. They are apex predators and feed on a variety of fish, invertebrates, and crustaceans.

Bonnetheads are relatively small sharks, typically reaching lengths of 1.5-2.5 meters (4.9-8.2 feet). They are known for their distinctive "bonnet" or hammer-shaped head, which is formed by the lateral extension of their skull. They have a distinctive pattern of dark gray or brown stripes or spots on their body, which vary by species and age.

Bonnetheads have a complex social structure and have been observed engaging in various behaviors, including mating, feeding, and territorial displays. Some populations are known to form large aggregations during certain times of the year. While they are generally considered harmless to humans, bonnetheads are still vulnerable to overfishing and habitat degradation, making conservation efforts necessary to protect this valuable species.
