Dolphins are one of the most cognitively complex animals on the planet. Here are five things they can do that researchers didn't expect to find in a non-human species.
They recognise themselves in mirrors. This ability - called mirror self-recognition - is a marker of self-awareness. Dolphins pass the test.
They call each other by name. Every dolphin develops a unique signature whistle. They use it across their lifetime and remember the calls of individuals they haven't seen in decades.
They invented tools and taught their daughters to use them. Bottlenose dolphins in Shark Bay, Western Australia carry sponges to protect their beaks while foraging, a behaviour passed from mothers to daughters across generations.
They coordinate complex, flexible hunts. Different pods use different strategies to herd and catch fish, techniques that are learned, not instinctive, and vary by community.
They carry their dead. Documented across multiple species, this behaviour points to social bonds that run deeper than most people realise.
The science on dolphin cognition has been building for decades. The more researchers look, the more they find.
These are the incredible animals we are fighting to protect - from captivity, from the Taiji hunts, from shark nets, from an ocean that needs stronger laws.
