Sometimes called the porcupine of Australia, they’re not directly related. Most fossil echidnas (genus Megalibgwilia) of recent epochs represent a type intermediate between today’s short- and long-beaked families. Echidnas constitute the family Tachyglossidae, and their only living relative is the platypus. Therefore, the full name of an organism technically has eight terms.

If she maintains contact with the original, she can continuously produce clones. The beak is similarly used to probe leaf litter of the forest floor for food. In doing so, they appear to sink straight down into the soil, and, once dug in, they are well camouflaged by their spines. Echidnas can be active day or night, probing along the ground slowly and deliberately as they search for prey, but they will shelter themselves from extreme midday heat in burrows or caves. They have surprisingly large brains for their size and well developed cerebral cortices. Ring in the new year with a Britannica Membership.

Like the short-beaked echidna, these species are highly variable in their fur and spine cover. But what really sets the echidna apart from other mammals? Disclaimer: Beneath the coat of spines is a well-developed subcutaneous muscle layer, which in part accounts for the animal’s surprising strength. Unlike other mammals, which typically have highly acidic stomachs, the echidna has low levels of acidity, almost neutral, with pH in the 6.2–7.4 range.

When frightened it will curl into a ball, with its snout and legs tucked beneath it and its sharp spines sticking out. The echidna is a carnivore which lives on a diet of insects. The genus Tachyglossus, the short-beaked echidna, is generally classified as a single species whereas the long-beaked echidnoa, Zaglossus, has at least three valid species including the most recently established, which is Zaglossus attenboroughi. Generally, its spines are much shorter and less numerous than those of the short-beaked echidna, and the fur ranges from medium to dark brown. Their long, cylindrical snouts can detect the small electrical currents put out by their prey. The platypus (Ornithorhynchus anatinus) is an odd-looking mammal with a broad bill (that resembles the bill of a duck), a tail (that resembles the tail of a beaver), and webbed feet.Another oddity of the platypus is that male platypuses are venomous. Echidnas appear to have once been widespread and diverse, and one especially large form measured more than 1 metre (3.3 feet) in length. The International Union for Conservation of Nature (IUCN) Red List of Threatened Species considers all three species to be critically endangered because of hunting (echidnas are edible) and loss of habitat.

Like the Platypus, the Short-beaked Echidna is an egg-laying mammal or monotreme and lays one egg at a time. They have few sweat glands and cannot pant to shed excess heat; thus, echidnas may die of heat stress if cool shelter is not found. The echidna looks fearsome enough, but it is a shy animal and would rather retreat than fight if disturbed. In fact, the echidna is the most primitive and most ancient living mammal. There are only 3 monotremes: the platypus and 2 kinds of echidna. Classification for Kingdom Plantae Down to Division Magnoliophyta. The oldest known fossil echidna was recovered from an eastern Australian cave deposit from about 17 million years ago (during the early Miocene Epoch). The predators of the echidna include goannas, dingoes, foxes, feral cats, dogs, eagles and Tasmanian devils and snakes. Echidna species can be distinguished by their spines, by the number of claws on their feet, and by the shape and length of the beak.

It can open its tiny mouth only wide enough to allow its wormlike tongue to protrude. Female echidnas lay eggs! Echidna consumes tissue and 'evolves' body parts, varying from wolf-like heads to legs. Echidnas are also called spiny anteaters because of the spines covering their bodies. This combination of spines, strength, and strategy makes the short-beaked echidna difficult prey, and in fact it does enjoy a fairly predator-free existence—although dingos and nonnative foxes, as well as automobiles, are occasional hazards. Echidnas from colder regions such as Tasmania have long fur that partially obscures the spines, whereas echidnas of arid zones can appear to be covered in spines to the exclusion of fur. Echidnas appear to congregate only during the breeding season, when a female may be followed by a train of suitors.

Echidnas probably evolved from some unknown monotreme ancestor during the Paleogene Period (65.5 to 23 million years ago). The eggs hatch after about 10 days and the young, emerge blind and hairless. Although the material is fragmentary, it suggests that basic echidna characteristics, such as the birdlike, toothless skull and robust skeleton specialized for digging, had evolved by this time. The short beaked echidna is between 30 and 45cm (12 to 18in) in length. The short-beaked echidna is probably Australia’s most widely distributed native mammal, but it is common only where hollow logs, underbrush, and caves allow it to find shelter and ample food in the form of ants, termites, and other invertebrates. 'hedgehog, sea urchin' Like their relative the platypus, echidnas have an unusually low but variable body temperature of 29–32 °C (84–90 °F) and cannot tolerate more extreme heat. In contrast, the adult weight of the eastern long-beaked echidna ranges from 4.2 to 9.1 kg (about 9 to 20 pounds). The short-beaked echidna is endemic to Australia.
