The male echidna's penis is 7 centimetres (2.8 in) long when erect, and its shaft is covered with penile spines. [29] These may be used to induce ovulation in the female. [30] It is a challenge to study the echidna in its natural habitat, and they show no interest in mating while in captivity. Prior to 2007, no one had ever seen an echidna ...
The short-beaked echidna (Tachyglossus aculeatus), also called the short-nosed echidna, is one of four living species of echidna, and the only member of the genus Tachyglossus. It is covered in fur and spines and has a distinctive snout and a specialised tongue , which it uses to catch its insect prey at a great speed.
Myrmecophagy means "ant-eating" (Ancient Greek: murmēx, "ants", and phagein, "to eat"); the related habit of termite-eating is termitophagy. The two dietary habits often overlap, as these eusocial insects live in large, densely-populated, terrestrial ant colonies or termite mounds , requiring specialised adaptations from any species that ...
The long-beaked echidna's walk presents multiple differences from a lizard's. An echidna's walking pattern is more upright than a lizard's, this represents a pattern closer to a parasagittal kind of therian. Echidnas and therians both have a dynamic equilibration rather than a static one. [10]
The eastern long-beaked echidna is a member of the order Monotremata. Although monotremes have some of the same mammal features such as hair and mammary glands, they do not give birth to live young, they lay eggs. Like birds and reptiles, monotremes have a single opening, the cloaca. The cloaca allows for the passage of urine and feces, the ...

When a concentration of ants or termites is detected, the aardvark digs into it with its powerful front legs, keeping its long ears upright to listen for predators, and takes up an astonishing number of insects with its long, sticky tongue—as many as 50,000 in one night have been recorded. Its claws enable it to dig through the extremely hard ...
