Porpoises are friendly marine mammals that belong to the family Phocoenidae. They are often confused with dolphins, but porpoises are generally smaller and have a more rounded snout. These creatures are known for their playful behavior and can often be seen swimming in groups. They communicate using a series of clicks and whistles, which helps them navigate and find food in the ocean. Porpoises primarily eat fish and squid, using their echolocation skills to hunt. They are found in coastal waters around the world, from North America to Europe. Sadly, some species of porpoises are endangered due to habitat loss and fishing practices, making conservation efforts essential for their survival.
