This week we have been watching this video: "25 Amazing Facts You Didn't Know About Animals". You can read its transcript.

TRANSCRIPT:

#25. Houseflies don't allow their short lifespans (14 days) to hinder their musical abilities. They always hum in the key of F.

#24. The ostrich: Ostriches can run faster than horses, and the male ostriches can roar like a lion.

#23. The bat. Bats are the only mammals that can fly.

#22. Kangaroo: Kangaros use their tails for balance, so if you lift a kangaroo's tail off the ground, it can't hop.

#21. Spider: On average, there are 50,000 spiders per acre in green areas.

#20. Tiger: Tigers not only have stripes on their fur, they also have them on their skin. No two tigers ever have the same stripes.

#19. Crocodile: Here’s a tidbit that might be useful if you plan on becoming the next Steve Irwin[http://en.wikipedia.org/wiki/Steve_Irwin]: To escape the grip of a crocodile’s jaw, push your thumb into its eyeball – It will let you go instantly.

#18. Flea: Fleas can jump up to 200 times their height. This is equivalent to a man jumping the Empire State Building in New York.

#17. Cat: A cat has 32 muscles in each ear.

#16. Elephant: Elephants can smell water up to 3 miles away. They are also one of the three mammals that undergo menopause -- the other two being humpback whales and humans.

#15. Koalas: Koala bears almost exclusively eat only eucalyptus leaves and nothing else.

#14. Beaver: Because beavers' teeth never stop growing, they must constantly gnaw on objects to keep them at a manageable length. Their teeth would eventually grow into their brain if they didn't maintain them.

#13: Ant: There are one million ants for every human in the world. These resilient creatures also never sleep and do not have lungs.

#12. Oyster: Oysters can change gender depending on which is best for mating.

#11. Butterfly: Butterflies have two compound eyes consisting of thousands of lenses, yet they can only see the colors red, green and yellow.

#10. Snail: Don’t try this at home, but a snail can grow back a new eye if it loses one.

#9. Turtle: You can tell a turtle's gender by the noise it makes. Males grunt and females hiss.

#8. Giraffe: Giraffes have no vocal cords and their tongues are blue-black in color.

#7. Squirrel: You might want to thank a squirrel the next time you enjoy the shade of a tree. Millions of trees are accidentally planted by squirrels that bury nuts and then forget where they hid them.

#6. Humpback whale: Humpback whales create the loudest sound of any living creature.

#5 Dog: Dogs' nose prints are as unique as human fingerprints and can be used to identify them.

#4. Seahorse: The slowest fish is the seahorse, which moves along at about 0.01 mph.

#3. Pig: Pigs communicate constantly with one another; more than 20 vocalizations have been identified that pigs use in different situations, from wooing mates to saying, "I'm hungry!"

#2. Poodle: Contrary to popular belief, French poodles actually originated in Germany.

#1. Hummingbird: Hummingbirds are the only birds that can fly backwards and their wings can beat at up to 80 times per second.


Have a nice weekend.
