Penguins are flightless birds with streamlined bodies and thick coats, making them perfectly suited for life on the ice. The emperor penguin grows to a height of up to 1.25 m and can weigh as much as 45 kg. They are excellent, fast swimmers. Emperor penguins can reach speeds of up to 30 km/h and dive down to 400 m. On land, penguins waddle or slide on their bellies, propelling themselves along with their feet or flippers. The penguins favourite dish is fish or squid but they need to look out for orcas to make sure they dont get eaten themselves.
