Scalloped hammerheads swim all around the globe in coastal temperate seas and are aggressive hunters, feeding on smaller fish, octopus, and squid, according to National Geographic. These sharks are victims of bycatch from commercial fishing, including trawls, purse-seines, fixed bottom longlines, and artisanal fisheries. Since they travel in large schools, many are often caught all at once. They're listed as "Endangered."
