Dolphins are carnivores, who live on a diet of fish, squid and crusta-ceans, while larger species might even go for a seal or a seabird. They have rows of fearsome teeth, but prefer to swallow their food whole.

Half asleep: Dolphins don’t just sleep with one eye open - they actually only doze with half of their brains at once. The phenomenon, known as unihemispheric slow-wave sleep, allows them to stay alert to predators while they nap. Each side gets about four hours of rest every day.
