Drinking seawater to survive
|
view preview
A seagull on a glass roof looking really cute. Seagulls are able to drink seawater to survive thanks to salt glands just above their eyes. These glands eliminate excess salt from the seawater and flush it out of the birds' nostrils in liquid form, an action that's often mistaken for a sneeze.

This mammal isn't a hybrid between a giraffe and a zebra
|
view preview
The Okapi is native to the Democratic Republic of the Congo in Central Africa. Despite the zebra-like stripes, it is actually more closely related to giraffes. While okapis travel for the most part by themselves within their home ranges, they still have ways of communicating with others whose ranges overlap.

By checking the ground, an okapi can tell if another okapi has been there. Males also mark their territory by urine spraying. Normally silent, female okapis vocalize only when they are ready to breed. ...
