Scalloped Hammerhead Sharks have a large body with a broadly arched, narrow-bladed head and a central notch with two smaller lateral indentations.
They are light grey or bronzey in color on the top and white on the underside with a dark spot on their lower caudal fin lobe.
They are found worldwide in warm temperate and tropical waters. They are coastal pelagic and can be found in depths of up to 1,600ft.

Scalloped Hammerhead Sharks are migratory and tend to travel in large schools.
They tend to be closer to the shore during the day and father out shore at night.
They form large schools, up to a hundred, during the day to obtain food easier, especially larger prey.
Juveniles will be closer to the surface while adults tend to stay much deeper in the ocean.
Scalloped Hammerheads are shy sharks and will avoid people if confronted.
Because they tend to form huge schools for migrating and breeding, they are extremely vulnerable to commercial fishing and are considered critically endangered. In the southwest Atlantic they have declined by 90% and up to 98% in the northwest Atlantic.
