The woodpeckers tongue is so long that it is not attached to the woodpecker's head as in most birds, but instead it curls back up around its skull, allowing it to be so long. Once the woodpecker locates an insects tunnel in a tree, it worms its tongue into the tunnel to try to locate the grub. The tongue of the woodpecker is long and ends in a barb. With its tongue the woodpecker skewers the grub and draws it out of the trunk.

When scientists first started capturing specimens of deep-sea Anglerfish, they noticed that all of the specimens were females. Almost all of them had what appeared to be parasites attached to them. It turned out that these "parasites" were the remains of male Anglerfish. The males have no digestive system, and thus are unable to feed independently. They must find a female quickly after hatching, or they will die.

The Irish Wolfhound is considered to be the largest breed of dog. Male Irish Wolfhounds average between 36-40"(85-90cm) at the shoulders(withers). The average life span of an Irish Wolfhound is only six and a half years. Because of the large size and short lifespan of this breed, the Irish Wolfhound has a phenomenal growth rate as a puppy. When fed a proper diet, Irish Wolfhound puppies can grow over 3/4"(2cm) a week in height, and gain up to 1 pound(.45kg) a day. Irish Wolfhounds can grow to full size in as little as 8 months, although they are still considered puppies until 18 months old.
There are tales of Irish Wolfhounds being used in war to dismount warriors from the backs of horses, and of the dogs chasing lions away in Africa.

A meteoroid is particle floating in outer space that has a size ranging between a grain of sand and large boulder 10-50 meters across. Once a meteoroid enters the earth's atmosphere and becomes visible, it is considered a meteor. Most meteors burn up before they reach the ground. The remains of a meteor that impacts the earth, if it is not vaporized by the impact, is called a meteorite. Anything larger than a meteoroid is considered an asteroid.
