Beaver Head

Beavers (Castor) are a genus of semi-aquatic rodents native to North America and Eurasia, characterized by their broad, scaly tails. They all live exclusively in the northern hemisphere, with the exception of some American beavers introduced in the Tierra del Fuego region of Argentina. Specimens of this species have also been introduced into certain regions of Europe.

Animals are multicellular life forms that engage in a form of heterotrophic metabolism and energy exchange, thus relying on body substance or metabolic products of other organisms for nutrition, and are not fungi. Within the terrestrial life forms, animals form a separate kingdom called Animalia. This kingdom is nowadays equated with the taxon of Metazoa. Accordingly, the group of the actual animals is congruent with the group of the multicellular animals. According to the modern view, unicellular animals do not exist, although this was traditionally seen differently. All animals evolved from a common ancestral form and are more closely related to each other than to any other living beings. The animal world is described by the term fauna. The natural science of the animals is called zoology.

Humans are counted among the animals in biology. Certain non-scientific disciplines - including jurisprudence and theology - do not count him among them. The relationship between animals and humans is the subject of research in animal philosophy.
