Hammerhead sharks are some of the strangest looking animals on this Earth. They are called  hammerheads as their head has two extended lobes, and it looks like a hammer. There are nine species of this shark found all around the world. Here are some facts about Hammerhead sharks.

Fact 1: The length of a Hammerhead shark varies greatly. It can be as short as 3 feet and as long as 20 feet which depends on gender, age, and species. The Great Hammerhead shark weighs around 1,000 pounds.

Fact 2: Not just their head but many other features make them different from other sharks. For instance, their dorsal fin is extended, and their head is mallet shaped.

Fact 3: Hammerhead sharks love to live in warm waters, so they are found all around the world in tropical and temperate regions. They are found near the shores, and in the summers they migrate towards colder waters.
