A Red Fox
  • Type of Animal: Mammal
  • Scientific Name: Vulpes vulpes (for the red fox, the most common species)
  • Where Found: Nearly worldwide, most abundant in the Northern Hemisphere
  • Conservation Status: Least Concern (for the red fox)

Foxes, particularly the red fox, are small to medium-sized omnivorous mammals, known for their cunning in folklore. A member of the Canidae family, the fox is distinguished by its pointed snout, bushy tail, and upright triangular ears. Foxes are highly adaptable and can be found in various habitats, including forests, grasslands, mountains, and deserts.

Their diet is as diverse as their habitat, feeding on small mammals, birds, insects, and fruit. Foxes are solitary hunters but often form monogamous pairs during breeding season. Their vocalizations are complex and can include a surprising variety of barks, howls, and screams.

Did you know? Foxes use the Earth’s magnetic field to hunt. They can see the magnetic field as a “ring of shadow” on their eyes that darkens as they head towards magnetic north. When the shadow and the sound the prey makes align, they leap in the air to catch the prey.


Red ants colony
  • Type of Animal: Insect
  • Scientific Name: Formicidae (family)
  • Where Found: Worldwide, except Antarctica and a few remote or inhospitable islands
  • Conservation Status: Not evaluated

Ants are small, social insects belonging to the family Formicidae. Known for their highly organized colonies and nests, ants play crucial roles in ecosystems as decomposers, predators, and seed dispersers. Ant colonies can range from a few dozen to millions of individuals and are often divided into worker, male, and queen castes.

Ants communicate and cooperate using pheromones and display remarkable abilities in navigation, problem-solving, and adaptation. They can be found in almost every terrestrial habitat, from rainforests to deserts. Ants have a diverse diet, including nectar, fungi, seeds, insects, and food scraps from human habitations.

Did you know? Some ant species are capable of ‘supercolony’ formation, where multiple colonies unite, forming a mega-colony. The largest recorded supercolony was over 3,700 miles wide!

Bee with pollen
  • Type of Animal: Insect
  • Scientific Name: Apidae (family)
  • Where Found: Worldwide, on every continent except Antarctica
  • Conservation Status: Varies by species

Bees are flying insects known for their role in pollination and, in the case of the best-known bee species, the European honeybee, for producing honey and beeswax. A vital part of the ecosystem, bees pollinate a significant portion of the crops humans consume. They belong to the family Apidae and include a diverse range of species, from solitary to highly social types.

Social bee species, like honeybees and bumblebees, live in well-organized colonies with a single queen, many workers, and, at certain times of the year, drones. Bees communicate with each other through a “dance” that conveys information about the location of resources. Their stings, while defensive, can be fatal to the bee, as they die shortly after stinging.

Did you know? Bees have five eyes – two large compound eyes and three smaller ocelli eyes in the middle of their forehead to detect light intensity.
