How does echidna reproduce?
Echidnas are monotremes which means that they lay an egg instead of giving birth to live young. The egg remains in the female reproductive tract until it is about the size of a grape. Once the egg has been laid, it remains in the female’s pouch for a further 10 days.

Does torpor affect reproduction in Tasmanian short-beaked echidnas?
Torpor during pregnancy in the Tasmanian short-beaked echidna Tachyglossus aculeatus setosus “We studied the interaction between torpor and reproduction in free-ranging female Tasmanian echidnas using a combination of techniques including urogenital smears, hormone analysis, ultrasonography, external temperature loggers and camera traps.

The species is currently secure throughout most of its present range. The short-beaked echidna is rotund and furred with a small head terminating in a cylindrical beak or snout. Adults can grow to a body length of 40 cm and weigh up to 7 kg.
