Did you know the giraffe has one of the shortest sleep requirements of any mammal?  They only need between 10 minutes and two hours in a 24-hour period.  Do you know any other interesting giraffe facts?  If so, comment below!

The African Grey Parrot is the world’s smartest bird. It can form it’s own small sentences and associate words with their meaning, as opposed to most birds that only mimic. The African Grey can also identify over fifty objects, seven colors, five shapes, numbers up to six, and can tell the difference between big or small and over or under!

Pigs have complex cognitive abilities. In laboratories, pigs play video games better than primates. They also dream and recognize their own names. Researchers identified more than 20 different squeals that pigs objectively respond to. Pigs also listen to music and mother pigs are known to sing for their young. Newborn piglets can identify their mother’s voice upon birth.
