Casu marzu is a traditional Sardinian sheep milk cheese, notable for containing live insect larvae. It is found almost exclusively in Sardinia, Italy.

Casu marzu is created by leaving whole Pecorino cheeses outside with part of the rind removed to allow the eggs of the cheese fly Piophila casei to be laid in the cheese. A female P. casei can lay more than five hundred eggs at one time. The eggs hatch and the larvae begin to eat through the cheese. The acid from the maggots' digestive system breaks down the cheese's fats, making the texture of the cheese very soft; by the time it is ready for consumption, a typical casu marzu will contain thousands of these maggots.

Termites are pretty astonishing creatures by anyone's standards -- their queens are thirty times the size of soldiers and they produce an amazing thirty eggs per minute.

Relative to their size, termites build the largest structures in the animal kingdom. Their towers can reach an incredible 25ft (7.6m) high and 40ft across (12.1m) - and that's just above the ground! They can burrow as far as 225ft (68m) below the surface.

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 Amazonian giant centipede is the largest centipede alive, reaching lengths of 30 centimeters. They are carnivorous and feed on lizards, snakes, mice, and even bats. While their venom is not enough to kill an adult human, it may cause reactions with the skin.

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 ...

This is the giraffe weevil from Madagascar, which, as you might have guessed, gets its name from its long neck. Males use their extra long necks for fighting, while females use theirs to roll a leaf nest, into which an egg is laid during reproduction.

The water beetle is about 1 mm in length and has been named Hydraena ateneo. Most of the discoveries made in the Philippines occur in their forests, making this discovery even more surprising.
