Mammals
Monotremes
The monotremes are the last of a dying race of ancient mammals. Monotremes were among the first mammals, but the number of species in the group is now down to three. They are the last group of mammals that lay eggs.
Short-Beaked Echidna
Tachyglossus aculeatus
The spines of this species, also called the spiny anteater, are longer than the fur between them. Active both day and night, this echidna is solitary and can become torpid in very cold or hot weather, when its temperature falls from the normal 88-92℉ (31-33℃) to as low as 39℉ (4℃). It eats a variety of ants, termites, grubs, and worms. These are detected by smell and perhaps by sensors on the long snout that detect electric signals. The head is small and there is no discernable neck.
Eastern long-beaked echidna
Zaglossus bartoni
The Eastern long-beaked echidna has, as the name implies, a longer beak than its short beaked cousin. It can grow up to eight inches in length, and curves downward. The echidna can grow up to two feet and can weigh up to 14 pounds. They are a bit more rare than their cousins, as they are listed as vulnerable.
