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 monotremes, including the semi-aquatic platypus and the terrestrial echidnas, are one of the only groups of mammals that have evolved electroreception. While the electroreceptors in fish and amphibians evolved from mechanosensory lateral line organs, those of monotremes are based on cutaneous glands innervated by trigeminal nerves.
Other monotremes also have developed the ability to electrolocate, but the platypus is the best at it among the monotremes. While the echidna species has 400 to 2,000 electroreceptor skin cells ...
Attenborough’s long-beaked echidna, which was thought to be extinct, has stunned scientists after being filmed in a tropical forest in Indonesia for the first time.. The egg-laying mammal, named ...
There are only five existing species of monotremes: the platypus and four species of echidna. “To a biologist, the idea that that branch could go extinct would be a great tragedy,” Kempton said.
Monotremes (/ ˈ m ɒ n ə t r iː m z /) are mammals of the order Monotremata.They are the only group of living mammals that lay eggs, rather than bearing live young.The extant monotreme species are the platypus and the four species of echidnas.
New Guinea's monotremes are restricted to the family Tachyglossidae, also known as echidnas. There are four species of echidnas in two genera: the short-beaked echidna ( Tachyglossus aculeatus ), the eastern long-beaked echidna ( Zaglossus bartoni ), the western long-beaked echidna ( Zaglossus bruijni ) and Sir David's long-beaked echidna ...
