Zaglossus attenboroughi, also known as Attenborough's long-beaked echidna or locally as Payangko, is one of three species from the genus Zaglossus that inhabits the island of New Guinea. [3] It lives in the Cyclops Mountains , which are near the cities of Sentani and Jayapura in the Indonesian province of Papua .
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 class Mammalia is divided into two subclasses based on reproductive techniques: egg-laying mammals (yinotherians or monotremes - see also Australosphenida), and mammals which give live birth ().
Echidna's family tree varies by author. [4] The oldest genealogy relating to Echidna, Hesiod's Theogony (c. 8th – 7th century BC), is unclear on several points. According to Hesiod, Echidna was born to a "she" who was probably meant by Hesiod to be the sea goddess Ceto, making Echidna's likely father the sea god Phorcys; however the "she" might instead refer to the Oceanid Callirhoe, which ...
The echidna spurs are vestigial and have no known function, while the platypus spurs contain venom. [42] Molecular data show that the main component of platypus venom emerged before the divergence of platypus and echidnas, suggesting that the most recent common ancestor of these taxa was also possibly a venomous monotreme.
Taking this one stage further, the clue word can hint at the word or words to be abbreviated rather than giving the word itself. For example: "About" for C or CA (for "circa"), or RE. "Say" for EG, used to mean "for example". More obscure clue words of this variety include: "Model" for T, referring to the Model T.
The long-beaked echidna's limb posture is sprawled, similar to extant reptiles like lizards and crocodilians. Although the stances between the animal groups are similar, the way the limbs move are very different between the clades. The echidna swings its limbs at a 45 degree angle while a lizard's is more horizontal.
The eastern long-beaked echidna can be distinguished from other members of the genus by the number of claws on the fore and hind feet: it has five claws on its fore feet and four on its hind feet. Its weight varies from 5 to 10 kilograms (11 to 22 lb); its body length ranges from 60 to 100 centimetres (24 to 39 in); it has no tail.
