The Short-Beaked Echidna, tachyglossus aculeatus, is one of the most distinctive and ancient mammals native to Australia, including Tasmania, and parts of New Guinea. Characterized by its spiny coat, short legs, and elongated snout, the echidna is an iconic example of a monotreme, or egg-laying mammal. Adults can weigh between 2 to 7 kg and are covered in coarse hair and sharp spines, which provide protection from predators. The echidna's snout is used for both smelling and breathing, and its small mouth at the end of the snout is specially adapted to eat ants, termites, and other small invertebrates.

Echidnas are solitary and primarily nocturnal, thriving in a wide range of habitats from forests and woodlands to grasslands and urban areas. They possess strong, clawed feet used for digging burrows and tearing into termite mounds. Despite their slow movement on land, echidnas are capable swimmers.
The diet of the Short-Beaked Echidna consists mainly of ants and termites. It uses its long, sticky tongue to capture prey, and its sharp beak to break into nests. Unlike most mammals, echidnas lack teeth, instead grinding their food between the base of their mouth and their tongue.
Reproduction is unique, as echidnas are one of the few mammals that lay eggs. The female lays a single, leathery egg into her pouch, where it hatches after about 10 days. The newborn, called a puggle, is hairless and spineless, feeding on milk secreted from the mother's mammary glands. The puggle remains in the pouch for up to two months before being weaned in a nursery burrow.
The population of the Short-Beaked Echidna is considered stable, but it faces threats from habitat destruction, road accidents, and predation by introduced species such as dogs and foxes. Conservation efforts focus on habitat preservation and reducing human impact. The echidna plays a vital role in ecosystem health by controlling insect populations and aerating the soil through digging, highlighting its importance in biodiversity conservation.

The short-beaked echidna is a monotreme, laying eggs instead of giving live birth.
These fascinating creatures are covered in spines and have a specialized snout for detecting and consuming ants and termites. Their tongue is incredibly sticky and can extend up to 18 cm to capture their prey. They are found mainly in Australia and New Guinea.
