Characteristics of echidna
What is echidna classification?
Echidnas (/ɪˈkɪdnəz/), sometimes known as spiny anteaters, are quill-covered monotremes (egg-laying mammals) belonging to the family Tachyglossidae /tækiˈɡlɒsɪdiː/. The four extant species of echidnas and the platypus are the only living mammals that lay eggs and the only surviving members of the order Monotremata.
What are the special characteristics of the monotremes?
In a number of other respects, monotremes are rather derived, having highly modified snouts or beaks, and modern adult monotremes have no teeth. Like other mammals, however, monotremes have a single bone in their lower jaw, three middle ear bones, high metabolic rates, hair, and they produce milk to nourish the young.
What do echidnas do?
The short, stout limbs of an echidna are well-suited for scratching and digging in the soil. The front feet have five flattened claws which are used to dig forest litter, burrow, and tear open logs and termite mounds. The hind feet point backwards, and help to push soil away when the animal is burrowing.
How do echidnas protect themselves?
Believe it or not, the spines you see on an echidna are actually long, tough, hollow hair follicles. These spines are an echidna’s main line of defence when predators strike. When under threat, they will roll up into a ball of radiating spines to protect themselves or dig themselves to safety.
Are echidnas shy?
threats to echidnas
Echidnas are generally shy animals, with a fairly placid nature. If disturbed or approached, an echidna will curl into a ball with snout and legs tucked beneath itself, concealing its head, with its sharp spines sticking out, deterring predators.
Are echidnas blind?
Eyesight is not a crucial factor in the animal’s ability to survive, as blind echidnas are able to live healthily. Its ears are sensitive to low-frequency sound, which may be ideal for detecting sounds emitted by termites and ants underground.
Do echidnas have good eyesight?
Echidnas have poor eyesight, and loud noise and bustle makes them bury themselves nervously. If you’re quiet, calm and patient you’ll see something marvellous.
Can echidnas hurt you?
Never try to dig out an echidna if it has burrowed into the ground. There is a very high risk of causing life-threatening injuries. If the echidna is in your yard and you are concerned for its safety, you should lock up any pets and prevent people from going near the echidna – it won’t move if it senses nearby threats.
What is the classification of a platypus?
The Platypus is a unique Australian species. Along with echidnas, Platypuses are grouped in a separate order of mammals known as monotremes, which are distinguished from all other mammals because they lay eggs.
Is an echidna a herbivore carnivore or omnivore?
Abstract. Short-beaked echidnas are considered myrmecophages, carnivores that specialize in eating termites and ants. Dogs and cats have been used as the carnivore models to develop their artificial diets. Echidnas appear to do well on artificial diets, often living 50+ years in captivity.
Is an echidna a marsupial?

Is an echidna a rodent?
Echidnas, also called spiny anteaters, are walking contradictions. They are mammals, but they lay eggs.
Can echidnas swim?
Echidnas are strong swimmers that have been observed swimming across creeks, rivers, dams and beaches in the past. Dr Peggy Rismiller, who has researched echidnas for more than 30 years, said the animals often enter the water to entertain themselves.
Are echidnas venomous?
“A waxy secretion is produced around the base on the echidna spur, and we have shown that it is not venomous but is used for communicating during breeding,” said Professor Kathy Belov, lead author of the study published in PLOS One today. Professor Belov is from the University’s Faculty of Veterinary Science.
