Bats fact sheet - Hero
  • Scientific name: order Chiroptera
  • Type of animal: Mammal
  • Where found: Worldwide except polar regions

Brown bear sheet - Hero
  • Scientific name: family Ursidae
  • Type of animal: Mammal
  • Where found: All continents except Antarctica and Australia

Found across multiple continents, these large mammals are symbols of strength and perseverance. They come in a variety of species, each with its distinct features and habitat preferences.

From the icy expanses of the Arctic where the polar bear reigns supreme, to the dense forests of North America where the grizzly bear lumbers about, these creatures have always captured human fascination. Bears have an uncanny intelligence and are incredibly adaptable. Their diets vary extensively, with some being omnivorous and others almost exclusively carnivorous or herbivorous.

Bears also play a crucial role in many ecosystems, helping to control populations of other animals and even aiding in the dispersion of seeds through their droppings. Their behavior, especially during hibernation, has been a subject of intrigue for many researchers. This deep sleep not only allows them to survive the winter without eating but also showcases an impressive physiological adaptation.

Did you know? Polar bears have black skin! Despite their thick, white fur which provides camouflage in the snowy Arctic environment, underneath it all, their skin is pitch black, helping them absorb and retain heat from the sun.


Beaver sheet - Hero
  • Scientific name:
    • Castor canadensis (North American beaver)
    • Castor fiber (Eurasian beaver)
  • Type of animal: Mammal
  • Where found: North America and Eurasia

Beavers, often recognized by their flat, paddle-like tail and sharp incisor teeth, are semi-aquatic rodents known as nature’s engineers.
