porpoise

A porpoise is a type of small whale that lives in oceans all around the world. It's often seen swimming close to shore.

You might have heard someone say "look, there's a porpoise!" when they're out on a boat or by the beach. That's because people are usually excited to spot one of these creatures gliding through the water with its sleek body and distinctive smile-like shape. Porpoises can grow up to 2 meters long and weigh as much as 160 kilograms, but they still look cute and agile in the ocean. Some people think porpoises are similar to dolphins, but they're actually a bit different - porpoises have a rounded head and no distinct beak like dolphins do.
