The Atlas beetle can push around 850 times its weight.

The coconut crab weighs about 6.6 pounds, and its legs can span up to two-and-a-half feet. Liz Hall from the Melbourne Aquarium inspected Coconut Crab as he took possession of a coconut on Dec. 19, 2006. The coconut crab (also known as the robber crab) is the largest living crab in the world and can climb coconut trees to harvest the nuts, which they can break with their huge nippers. They've also been gruesomely known to feed on injured or unconscious people in the bush.

The giant squid is the world's largest invertebrate, and the largest such squid ever measured was 59 feet long. Giant squids also have the largest eyes of any animal, each one about the size of a human head.

The Etruscan shrew is the smallest mammal (by weight) in the world. The smallest animal by skull size is the bumblebee bat.

North African ostriches run up to 45 miles an hour, making them the fastest land bird. They are also the biggest, weighing up to 345 pounds. An African ostrich eats at the Addo National Elephant Park, north of Port Elizabeth, on June 24, 2010.
