If you have a house centipede crawling around on your floors, you’re in luck! These little guys feed on pests such as termites, cockroaches, spiders, and ants to keep your home’s biodiversity to a minimum. Adult centipedes have 15 pairs of legs that help it achieve top speeds of 0.4 meters per second. To mate, centipedes become acquainted through the touching of antennae, and the male deposits sperm onto the ground, which the female then uses to fertilize her eggs.

The wrinkle-faced bat is found in some regions of Central and South America. If you’re worried about this coming after you in the night, don’t be. It feeds only on fruit, preferring juicier, overripe mangos and bananas. Actually, it’s quite helpful to humans because it pollinates crops.

In the Amazon rainforest salt is a highly sought after commodity. Tears are full of salt, so these butterflies are literally drinking the turtles tears to get the vital mineral.

This is a fairly common sight in the Amazon, and it's not restricted to butterflies.

Roll cloud over Uruguay. This low, roll cloud formation occurs when sinking cold air causes warm, moist air on the planet's surface to climb to higher altitudes, where the moisture condenses into cloud form. Roll clouds aren't dangerous in themselves, though, and many roll clouds form in relatively calm weather as a result of sea breezes.

Funnily enough, our planet apparently did once have rings. According to current theories, millions of years ago a planet-sized body called Theia collided with Earth. A huge amount of material from Earth was blown up into orbit by the impact, where it formed a ring. Because this material was orbiting outside of earth's Roche limit, it eventually coalesced into the Moon.

These illustrations by Ron Miller show what our skies would look like if we had rings that were the same proportional size and position as Saturn's. ...

The bullet ant, or Paraponera clavata, lives throughout Central and South America. What makes this ant a formidable insect are its large mandibles and stinger. The bullet ant is one of the largest ants, growing to a length of just under 1 inch. Most notable about the ant is its ability to produce an excruciating sting.

Latrodectus mactans, or Southern black widow or simply black widow, is a highly venomous species of spider. They are well known for the distinctive black and red coloring of the female of the species and for the fact that she will occasionally eat her mate after reproduction (hence the name – Black widow). The species is native to North America. The venom might be fatal to humans.

Although these spiders are not especially large, their venom is extremely potent. They are capable to inject the venom to a point where it can be harmful. The males, being much smaller, inject far less venom. The actual amount injected, even by a mature female, is very small in physical volume. When this small amount of venom is diffused throughout the body of a he ...
