Tasmanian Devils are reintroduced into Australia’s mainland

Eleven Tasmanian Devils (Sarcophilus harrisii) from the island state of Tasmania have been reintroduced into the mainland of Australia for the first time in 3,000 years.

The Tasmanian Devil is a marsupial mammal, an animal with a pouch. It once roamed the mainland of Australia and is now listed as endangered on the International Union for Conservation of Nature (IUCN) Red List. The Tasmanian Devil lived on the the mainland of Australia for 40,000 years until it died out due to the European introduction of foxes and cats in the 19th century that preyed on many native marsupial mammal species.

The Tasmanian Devil continued to live on the Tasmanian island in southern Australia, but many died over the past 20 years, since 2000, due to the Devil Facial Tumor Disease (DFTD), which is a cancer of the face. It is estimated that there are only 25,000 Tasmanian Devils left in Tasmania.

Does the Mexican Walking Fish actually walk?

Does the Mexican Walking Fish actually walk?

The Mexican Axolotl (Ambystoma mexicanum) is a freshwater amphibian in the salamander family. It is also known as the Mexican Walking Fish, but it is not a fish. Toads, frogs, newts, salamanders and axolotl are amphibians, living partly in water and partly on land. 

Unlike other amphibians, the Mexican Axolotl never leaves the water – it remains aquatic and never goes on land, so it does not walk on land.

Changing colour for winter

What animals change colour for winter?

Many animals, especially mammals, hibernate (sleep) in winter. Some animals lie dormant (similar to sleep, but lie still). Other animals, such as butterflies and moths and other insects, turn into cocoons and chrysalises in winter, waiting to emerge as adults in spring. Other animals grow their winter fur to keep them warm.

But some animals change colour to camouflage into their autumn and winter environment – brown among dry leaves and leaf litter, white in snowfields, and grey in clouded habitats.

Anatomy of a Snail’s Head

What does a snail’s head look like?

A snail’s head has one or two pairs of retractable tentacles: upper tentacles and lower tentacles.

Kirk’s Dik-Dik baby

The Kirk’s Dik-Dik (Madoqua kirkii) is a small mammal in the Bovidae family of antelopes from East Africa.

It lives in pairs, mating for life. The female is pregnant for 5-6 months, and may have one or two babies per year. The mother hides her young in long grass to avoid predators, such as cheetahs, leopards, lions, eagles, hyenas, crocodiles, baboons, and jackals.
