Which is the smallest mammal in Europe

Small, smaller, smallest ...

Many invertebrates are so small that they are invisible to humans with the naked eye. These include, for example, some species of dwarf wasps that colonize almost the entire earth, but remain largely undetected due to their small body size. The smallest wasp, the Kikiki Huna, which is native to Costa Rica, measures only a fraction of a millimeter and is therefore considered the smallest insect in the world. Some species of mites and the dwarf beetle Baranowskiella ehnstromi, which is widespread in Europe, are only a fraction of a millimeter long and are therefore only visible to humans under a magnifying glass or microscope. In addition to such tiny representatives of insects and arachnids, however, it is above all some species of vertebrates that cause surprises with their small body size.

There are two types of monkeys and primates that, because of their minimal size, fit in the palm of an adult human. With an average body length of nine centimeters, the Berthe mouse lemur (see also Koboldmaki) is the smallest representative of the primates. It can only be found in the Kirindy Mitea National Park in Madagascar and is therefore a very rare species. The pygmy marmoset or Cebuella pygmaea is a bit larger, but is still tiny, and is considered the smallest of the real monkeys due to its head-rump length of an average of 13 centimeters. The pygmy marmoset prefers to live in the high treetops of the rainforests of Colombia, Ecuador, Bolivia and Peru and weighs just 15 grams at birth.
The pig-nosed bat, which lives in Thailand and hardly grows larger than 33 millimeters, is considered to be one of the smallest mammals on earth. These animals live together in colonies that can contain up to a hundred animals. Biologists assume that the population is now limited to around four thousand specimens that live in several caves in Thailand and Burma. The pig-nosed bat shares its role as the smallest mammal with the Etruscan shrew, about whose way of life relatively little is known. It is native to the Mediterranean area, among other places, and is also barely larger than 35 millimeters. In contrast to the tiny bat, however, it is not considered endangered because it colonizes many habitats and is often close to human settlements. Also among the hares is Brachylagus idahoensis, an absolute tiny creature known in the German-speaking world as the dwarf rabbit. However, it is not closely related to the much larger dwarf rabbit, which is popular as a pet. This world's smallest representative of the hares, native to the western USA, reaches an average length of around 24 centimeters, with the females becoming significantly larger than the males. Several times a year they give birth to up to eight young animals, which measure barely more than seventy millimeters at birth.

The bee elf, a species of hummingbird native to Cuba, is not only the smallest bird in the world, but also describes that representative of the warm-blooded vertebrates that reach the smallest body size. Adult specimens measure an average of just five or six centimeters and weigh a maximum of two grams. The nest of this hummingbird in which the female bee-elf lays her eggs is correspondingly tiny. With a diameter of a few millimeters, these are hardly larger than small peas.
Among the fish, the Stout Infantfish, only native to Australia, a representative of the goby-like species with a body length of a few millimeters, is considered to be the world's smallest species. Paedocypris, which measures a maximum of eight millimeters, is also one of the smallest representatives of the fish. Its small body size makes this species native to the Sumatra swamps an absolute survivor, as it can survive phases of extreme dehydration without any problems and feels most comfortable in particularly acidic waters with a pH value of up to 2.9.
As the smallest turtle in the world, Homopus signatus measures just six to a maximum of eight centimeters, with the genus Leptotyphlopidae living in America, Africa and Asia almost ninety different species of snakes, which are known as the smallest representatives of this order with a maximum length of only eleven centimeters are.
