The animal of the day is the Gannet. (Did you know: The Gannet is the largest sea bird in the Atlantic, and 2nd largest in the world [to the albatross]. They are known for their impressive diving and underwater swimming abilities.
The have some cool adaptations that help them swim underwater. First of all, they have no external nostrils (WHAT?!), their nostrils are INSIDE their mouths! So when they dive, they just have to keep their trap shut.
Second, and this is weird, they have air sacs in their face and chests that act like bubble wrap protecting them as they slam into the water at high speeds!
The gannet’s supposed capacity for eating large quantities of fish has led to “gannet” becoming a disapproving description of somebody who eats excessively, similar to “glutton”.
