 | | Diving penguins reach 6 to 12 km/h, though there are reports of velocities of 27 km/h (which are probably realistic in the case of startled flight). |
 | | Penguin is thought by some to derive from the Welsh words pen (head) and gwyn (white), applied to the Great Auk, which had a conspicuous white patch between the bill and the eye (although its head was fl), or from an island off Newfoundland known as "White Head" due to a large white rock. |
 | | Penguins are popular around the world owing to their harmless nature, their upright stance for standing and walking, which humans find charming or comical, and their striking fl and white plumage that is often humorously likened to a tuxedo suit. |
