House mice can live in cold storage rooms where the temperature is less than -10 degrees Celcius (-17 degrees Fahrenheit) and there is no light at all. They are able to eat frozen meat and build their nests out of packaging or carcasses.

The bombardier beetle has a very unusual system to defend itself from predators. It can release two chemicals from its anus, which react to release heat of up to 100 degrees Celcius (212 degrees Fahrenheit).

The highest G-force achieved by an insect (without using its legs) is about 400 G, or 400 times the force of gravity. It is achieved by the click beetle Athous haemorrhoidalis, which bends its body and then straightens up to shoot 15 cm (6 in) into the air, although one specimen managed 30 cm (12 in).

The country with the most prisoners is the USA, with more than two million prisoners, or a quarter of all prisoners in the world. Yet the USA has just five percent of the world's population. This corresponds to 565 prisoners per 100 000 people.

The slowest mammal on earth is the South American sloth, which has an average ground speed of just 1.8-2.4 metres (6-8 feet) per minute, or .1 to .16 km/h (.07-.1 mph). A sloth's digestive system is equally sluggish and it might take a month or more for food to pass from a sloth's stomach to its intestine.
