Solitary Hunters in Tropical Waters
The Hammerheads are light grey with a greenish tint, with white undersides. The mouth is disproportionately small, compared to its size. In the day, they form schools of up to 100 individuals, and at night, they become solitary hunters. Warm tropical waters are the preferred habitat of the Hammerheads, all over the world. During the summer, mass migration occurs, in the search of cooler waters. These sharks may be found in waters ranging from less than 1 meter (3.3 ft), up to a depth of 80 meters (260 ft) offshore.
The Hammerhead’s diet
The Hammerhead’s diet consists of octopus, squid, many species of fish, including other sharks, and stingrays, which are a particular favourite. The sharks are often found swimming at the bottom of the ocean, in order to stalk their prey. The shark’s unique hammerhead is used to pin the stingray down, and the prey is then eaten while it is weak and in shock. The largest of the Hammerhead group, the Great Hammerhead, is known to engage in cannibalism, eating other Hammerheads, including its own young. Another shark in this group, the Bonnethead, has been found to eat seagrass, along with the usual prey. The seagrass sometimes makes up for half of their stomach contents and they can partially digest it. This makes it the only shark that shows potentially omnivorous traits.
