Hoping to impress that cute dog walker in the park? Or just want to be the center of sparkling conversation at your next dinner party? You're in luck. We’ve got a concise collection of fun facts about the animal kingdom to keep any conversation going strong. Without further ado, here are 10 facts that almost nobody knows.|
No.10 Certain Baby Dolphins and Whales Never Sleep
Ever seen a motionless baby whale? We didn’t think so. For the first month of their lives, newborn bottlenose dolphins and killer whales never sleep but remain mobile 24 hours a day. Similarly, sharks have no air bladders, so they have to swim constantly or they'll sink. On the luckier end of the scale are albatrosses, who can sleep while in flight. Giraffes tend to get a lot done, as they rarely sleep more than 20 minutes a day.
No.9 Ants Enslave Other Ants
There are ant species that make slaves of others. The enterprising insects will go out and raid the nests of other species nearby, stealing their eggs and pupae. These are taken home, and the unwitting young are raised as slaves, having to do all the foraging, cleaning and babysitting for their masters.
No.8 Crickets Can't Stop Moving Or Else...
Has your road trip been hampered by a 10 kilometer-long swarm of something you do not want slamming the windscreen? Looks like you’ve bumped into a chirp-happy crew of Mormon crickets. These Jiminys keep on the move not just to find food, but to avoid being eaten by each other. If one of them stops for any reason, it is likely to be devoured by some of the millions of its following brethren. At least it’s fast.
No.7 The Bone Mass Of Iguanas Shrinks And Grows
The Galapagos marine iguana not only holds the prestigious title of the only sea-going lizard, but is also the only vertebrate (besides Scarlett Johansson) known regularly to shrink and grow in body size. But we’re not talking getting fat and slimming down here. The iguanas shrink up to 15% in body length, losing bone mass. The following year the iguanas supersize themselves before getting smaller again, and so on.
No.6 Sparrows Get Jealous
House sparrows are a promiscuous lot, but the ladies know how to stay ahead of the game. A female house sparrow will often seek out the nest of another female that her partner has also mated with and will then kill the first female's young. This removes the competition for her man, ensuring he spends as much time as possible helping to raise her chicks.
