Did you know a baby echidna is called a puggle? A Tasmanian echidna showing its fur coat, Liffey River Reserve. Short-beaked Echidnas can grow up to 40cm and 7kg, but most are between 2kg and 5kg.

Echidnas then slurp up ants and other insects with their sticky, saliva-covered tongue, which can be 17cm long!

Echidnas have a very keen sense of smell, useful in locating mates, detecting danger and snuffling for food. Their short limbs and shovel-like claws are perfect for digging out food and burrowing in the soil. Instead, they use their hard, sharp spines for protection. Below these 5cm-long spines, echidnas are covered in short black hair, helping them to live in a wide variety of habitats. Mothers return every five to ten days to nurse the young. Short-beaked echidnas in Tasmania remain in nursery burrows with the young for 25 to 35 days post-birth.

Mothers then return to the burrow every three to five days to nurse. Other subspecies exhibit variations of parental care ranging between these two extremes. Mothers do not have nipples or teats, but nurse young through pores connected to their paired mammary glands. The longest recorded lifespan for Tachyglossus aculeatus is 50 years in captivity. There are anecdotal accounts of wild individuals living as long as 45 years.

There is no doubt this species is particularly long-lived, especially for its size. A lifespan of 50 years is 3. Other long-lived mammals have been observed to have peroxidation-resistant membrane composition, which describes the ratio between polyunsaturates and monounsaturates in membrane lipids. Short-beaked echidna membranes were found to have lower polyunsaturate and higher monounsaturate levels than expected. This composition indicates peroxiclation-resistant cellular membranes in T.

Lifespan is also associated with the production of free radicals, which is proportional to metabolic rate. Short-beaked echidnas have notably low metabolic rates, with the exception of times of arousal from torpor. During these arousal periods, metabolic rates increase by up to nine times that of basal metabolic rates and free radical production is high. Therefore, T. A large and complexly-structured brain may be involved with longevity in T.

Such brain characteristics are often correlated with life history traits like slow maturation and single births in other mammals. These traits, in turn, correlate with a long lifespan. Hulbert, et al. Short-beaked echidnas are semi-fossorial, digging in substrate for hibernation cover and to construct nursery burrows. They decrease energy usage by hibernating from early autumn to late spring.

Short-beaked echidnas reduce their body temperature to 8 to 10 degrees C during torpor and use behavioral thermoregulation to maintain that preferred body temperature. During early hibernation, individuals prefer cooler soil temperatures compared with the coldest period of hibernation, at which time they will move to warmer hibernacula. During hibernation there are periodic arousals from torpor.

The timing of hibernation seasons varies by subspecies, geographic location, sex, and reproductive state. Short-beaked echidnas are flexible in their exploitation of substrates for hibernacula, commonly using leaf litter and grass tussocks. Nicol and Anderson, b ; Nicol and Anderson, a. Short-beaked echidnas nest at temporary sites, and have overlapping home ranges.

Their movements depend on food availability and not territoriality. Short-beaked echidnas sense other echidnas predominantly through smell. Recent findings suggest feces piles act as an important intra-specific form of communication. Elridge and Mensing, ; Nicol and Anderson, a. Adult short-beaked echidnas eat ants, termites, and other invertebrates.

They make foraging pits by disturbing the soil when looking for food, and they prefer foraging under the canopies of large trees. Their long snouts and sticky tongues reflect their specialized diet. Short-beaked echidnas dig into ant and termite nests with their front paws and poke their long, sticky tongue into nest crevices and grinds insects with its tooth pads.

Their foraging habits make separating soil from food difficult. Thus, much of their feces consists of soil. Predation is not a major threat to short-beaked echidnas, even though feral cats, pigs, dingoes, and goannas are occasional predators.

The echidna's genetic makeup does code for four peptides that are also found in platypus venom, the researchers found. But these genes are not highly expressed in the echidna, indicating "that they are the remnants of the evolutionary history of the ancestral venom gland," the researchers wrote in the study.

Echidnas are found only in Australia and New Guinea. They have the widest distribution of any native mammal in Australia and prefer alpine meadows, coastal forest and interior deserts, according to the San Diego Zoo. Echidnas are very solitary animals, but they are not territorial and are willing to share their home range with others of their kind. They are active during the day, but in warmer months they will often become nocturnal to avoid the heat. Echidnas have body temperatures of 89 degrees Fahrenheit 32 Celsius and very slow metabolisms.

This is thought to be one of the reasons why they live up to 50 years, according to National Geographic. Echidnas hibernate during the cold winter months in burrows. Echidnas have no teeth and only eat termites, ants and other soil invertebrates. They particularly love beetle larvae, according to the Australian Zoo. Their strong claws help them break open logs to get to termites that they scoop up with their long tongues, which can reach up to 7 inches 18 cm long when extended.
