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 Eastern species is listed as vulnerable, while the Attenborough's and western long-beaked echidna species are listed as Critically Endangered by the IUCN. [4] [5] [6] A number of extinct species were known in the genus, but they are currently treated as members of their own genera, such as Murrayglossus and Megalibgwilia.
In 2007, Attenborough's long-beaked echidna was identified as one of the top-10 "focal species" by the Evolutionarily Distinct and Globally Endangered (EDGE) project. [10] As of 2017, this species of echidna was among the 25 "most wanted lost" species which are the focus of Re:wild's "Search for Lost Species" initiative. [11]

The species has been found in locations up to an elevation of around 4,150 m (that is, the highest elevations available on New Guinea). [2] Zaglossus bartoni is currently listed as "vulnerable" on the Red List, improved from "critically endangered" until 2016. [2] Deforestation is one of the factors leading to the decline of this species.
