Arcadia trees, which grow all over the African savannah, have a unique defense system. When animals like antelopes start to gobble up its leaves, the tree increases tannin production to levels that are toxic to animals.
But that's not all. The tree then emits a cloud of ethylene gas that travels through the air, reaching other trees so they too can begin producing more tannins.

2Owls don't have eyeballs.
What they have instead are better described as eye tubes. Since they can't move these tubes back and forth, owls have developed incredible neck flexibility to be able to see the world around them. They can turn their heads a whopping 270 degrees, whereas humans can only manage about 180.
As a result, owls have a special blood vessel system in their heads to keep fresh blood circulating to the brain when a quick head turn cuts off circulation.

3In space, metal can weld on its own.
On Earth, you need heat to fuse metal, but in space, two pieces of the same kind of metal will fuse together with only a little pressure. The process is called cold welding, and it happens because of the lack of atmosphere.
4There are 28 kinds of "corpse flowers."
You might not know about the plant genus Rafflesia, but you may have heard about the "corpse flower," a rare type of jungle plant that attracts pollinating insects to its huge flowers by smelling like death and rot.
In fact, there are 28 distinct species of this rootless, leafless plant, with flowers varying in size from about 5 inches to 40 inches. Most of these flowers take six to nine months to grow and will begin to decay within a few days.
Fun fact: The Pokémon characters Vileplume and Gloom were inspired by this unusual flower.
