The biggest sharks in the ocean include the whale shark, megamouth shark, and basking shark. You might be surprised to learn that the three largest sharks in the world’s oceans are all filter feeders despite their size.

These massive creatures pose no threat to humans and subsist on incredibly small zooplankton while cruising passively around the ocean. Other large species of shark, like the thresher shark and Greenland shark, have other interesting attributes, like a whip-like tail and extreme longevity, that make them notable in addition to their size.
