Long-beaked echidnas have a narrower range and are confined to New Guinea due to their need for a humid environment. Short-beaked echidnas can survive in more arid environments as their diet provides the moisture necessary for survival. Short-beaked echidnas can inhabit anywhere from temperate or tropical forests to sandy deserts. Both genera of echidnas have specialized feet for digging and burrow for shelter. There has been evidence of short-beaked echidnas temporarily residing in abandoned rabbit burrows for cover. Home ranges of echidnas is highly variable based on their location, but males' ranges are typically twice the size of that of a female鈥檚. Overlap between ranges of two individuals may occur, but territory does not lead to hostility between the two. There is no home den that individuals continue to reside in, but nursery burrows may be constructed by females during reproduction periods. <span class="citations"> (<a href="#5875BCDC-4625-11EA-A862-005056AB59D3" class="citation">Beer, 2004</a>; <a href="#E6C4D1E6-462D-11EA-89FE-005056AB59D3" class="citation">Burnie and Wilson, 2011</a>; <a href="#5D3056DA-462D-11EA-AE71-005056AB59D3" class="citation">Cooke, et al., 2008</a>; <a href="#3FA80396-461A-11EA-89FE-005056AB59D3" class="citation">Nowak, 2018</a>)</span></p> <ul class="keywords donthyphenate "> <li class="keywords-header">Habitat Regions</li> <li> <a class="gloss" href="#20020904145595">temperate</a> </li> <li> <a class="gloss" href="#20020904145598">tropical</a> </li> </ul> <ul class="keywords donthyphenate last"> <li class="keywords-header">Terrestrial Biomes</li> <li> <a class="gloss" href="#20020904145626">desert or dune</a> </li> <li> <a class="gloss" href="#20020904145599::20020904145583::20020904145682">savanna or grassland</a> </li> <li> <a class="gloss" href="#20020904145828">forest</a> </li> <li> <a class="gloss" href="#20020904145487">rainforest</a> </li> </ul> </section> <section class="hyphenate"> <h3 id="taxonomic_history">Systematic and Taxonomic History</h3> <p audience="advanced intermediate">Echidnas are closest related to <a class="taxon-link" href="/accounts/Ornithorhynchus_anatinus/">platypuses</a> as they are the egg-laying mammals and form the order Monotremata. Monotremes and marsupials make up the basal taxa of mammals, Theria- the non-placental mammals. Monotremes produce milk, but lack teats. Fossil records provide evidence that mammal ancestors dating back to 220 million years ago were able to suckle based on bone structure and muscle attachment. Monotremes diverged from the mammals around 190 million years ago and therefore lost the ability to suckle. It is hypothesized the loss of the soft palate to allow for sucking occurred as an adaptation to their diet of hard-shelled prey. The genus of short-beaked echidnas has the following synonyms: <em>Acanthonotus</em>, <em>Echidna</em>, <em>Echinopus</em>, <em>Syphonia</em>. The genus of long-beaked echidnas has the following synonyms: <em>Acanthoglossus</em>, <em>Bruynia</em>, <em>Proechidna</em>, <em>Prozaglossus</em>. The synonyms are a result of names that were once established but are now incorrect due to Principle of Priority. <span class="citations"> (<a href="#10308C90-462A-11EA-A862-005056AB59D3" class="citation">Vogel, 2018</a>; <a href="#C2D8755A-63C2-11EA-BACF-005056AB59D3" class="citation">Wilson and Reeder, 2005</a>)</span></p> <ul class="aside block-grid donthyphenate two-up"> <li> <dl> <dt>Synonyms</dt> <dd> <ul> <li> <em>Acanthonotus</em> </li> <li> <em>Echidna</em> </li> <li> <em>Echinopus</em> </li> <li> <em>Syphonia</em> </li> <li> <em>Acanthoglossus</em> </li> <li> <em>Bruynia</em> </li> <li> <em>Proechidna</em> </li> <li> <em>Prozaglossus</em> </li> </ul> </dd> </dl> </li> <li> <dl> <dt>Synapomorphies</dt> <dd> <ul> <li>Cloaca</li> <li>Oviparious</li> <li>Fur/Hair</li> <li>Mammary Glands</li> <li>3 inner ear bones</li> </ul> </dd> </dl> </li> </ul> </section> <section class="hyphenate"> <h3 id="physical_description">Physical Description</h3> <p audience="advanced intermediate">Echidnas lay eggs and are therefore classified as monotremes along with <a class="taxon-link" href="/accounts/Ornithorhynchus_anatinus/">platypuses</a>, forming the basal taxa of mammals. Echidnas are covered in brown or black fur, with spines along the dorsal side of the body for protection. Short-beaked echidna spines are typically yellow, fading to black at the tip. Long-beaked echidnas have fewer spines that are white, gray, or black. Short-beaked echidnas can be 30 to 45 cm in length and weigh from 2.5 to 7 kg, with a beak approximately half the length of the head and a short tail, typically around or under 100 mm. Long-beaked echidnas are a little larger from 60 to 100 cm in length and weighing 5 to 10 kg and a beak length ranging from 100 mm to 150 mm. This length creates a downward curve in their beaks. While echidnas lack teeth, their extended snouts have pores for electroreception and sticky tongues to assist in achieving a meal. They have short stout legs with long claws for digging. Their hind feet are also pointed backward, which gives them an unusal gait. The hind feet also have a spur on the inner ankle. While in the monotreme <a class="taxon-link" href="/accounts/Ornithorhynchus_anatinus/">platypus</a> males have a venomous spur, both male and female echidnas have spurs without venom. <span class="citations"> (<a href="#5875BCDC-4625-11EA-A862-005056AB59D3" class="citation">Beer, 2004</a>; <a href="#E6C4D1E6-462D-11EA-89FE-005056AB59D3" class="citation">Burnie and Wilson, 2011</a>; <a href="#5D3056DA-462D-11EA-AE71-005056AB59D3" class="citation">Cooke, et al., 2008</a>; <a href="#3FA80396-461A-11EA-89FE-005056AB59D3" class="citation">Nowak, 2018</a>; <a href="#E7520F98-4623-11EA-AE71-005056AB59D3" class="citation">Rismiller and Grutzner, 2019</a>)</span></p> <ul class="keywords donthyphenate "> <li class="keywords-header">Other Physical Features</li> <li> <a class="gloss" href="#20020916130951">endothermic</a> </li> <li> <span>homoiothermic</span> </li> <li> <a class="gloss" href="#20020904145642">bilateral symmetry</a> </li> </ul> <ul class="keywords donthyphenate last"> <li class="keywords-header">Sexual Dimorphism</li> <li> <span>sexes alike</span> </li> </ul> </section> <section class="hyphenate"> <h3 id="reproduction">Reproduction</h3> <p audience="advanced intermediate">Echidnas are typically solitary outside of mating.

Breeding season occurs from July to August. Echidnas only have one young a year. They have one external opening called a cloaca for expelling waste and reproduction. Males have penises made for only copulation. The penis is bifurcated and forked at the end, giving the males a four-headed penis. Females produce one small, nearly round, leathery egg from the cloaca and transfer it directly to their pouch where it incubates for an average of ten days. Mothers prepare for hatching in this time by finding or digging a burrow. Observances of captive echidnas breeding in the Perth Zoo demonstrate nearly identical patterns to that of reproduction in the wild. <span class="citations"> (<a href="#5875BCDC-4625-11EA-A862-005056AB59D3" class="citation">Beer, 2004</a>; <a href="#DEFA892A-462C-11EA-AE71-005056AB59D3" class="citation">Ferguson and Turner, 2013</a>; <a href="#3FA80396-461A-11EA-89FE-005056AB59D3" class="citation">Nowak, 2018</a>; <a href="#E7520F98-4623-11EA-AE71-005056AB59D3" class="citation">Rismiller and Grutzner, 2019</a>)</span></p> <ul class="keywords donthyphenate last"> <li class="keywords-header">Key Reproductive Features</li> <li> <a class="gloss" href="#20020904145584">seasonal breeding</a> </li> <li> <span>gonochoric/gonochoristic/dioecious (sexes separate)</span> </li> <li> <a class="gloss" href="#20020904145786">sexual</a> </li> <li> <a class="gloss" href="#20020904145572">oviparous</a> </li> </ul> <p audience="advanced intermediate">Male echidnas do not have parental investment so echidna mothers provide all care for their offspring.

Echidnas do not have teats, but rather milk patches where milk simply leaks out. After 50 days, the mothers are able to leave the young in a burrow to forage for food. They return every 5 to 6 days to feed their offspring. When mothers leave the den, they cover the entrance with soil to keep their puggles safe from predation.
