Monotremes, which include echidnas and platypuses, differ in many aspects of their biology to all other mammals. Most distinctly, they lay eggs into a transient pouch rather than giving birth to live ...

Outliers among mammals, monotremes lay eggs instead of giving birth to live young. Only two types of monotremes, the platypus and echidna, still exist, but more monotreme species were around about 100 ...

The identification of a key gene in monotremes has increased our understanding of why the stomachs of platypuses and echidnas are atypically small, non-acidic, and, in the instance of platypuses, lack ...

Monotremes display a unique mix of mammalian and reptilian features and form the most distantly related, and least understood, group of living mammals. Their genetic blueprint provides fundamental ...

Six monotremes living in the same place at the same time, 100 million years ago at Lightning Ridge, NSW. Clockwise from lower left: Opalios splendens, a newly described species dubbed an ‘echidnapus’; ...

The platypus and echidna, often regarded as some of the most peculiar animals on Earth, may be hiding a far more complex evolutionary story than scientists initially believed. Recent findings from a ...

The findings were led by two mammalogists, Honorary Associate of the Australian Museum, Professor Tim Flannery; and Professor Kris Helgen, Chief Scientist and Director of the Australian Museum ...

A heartwarming rediscovery has been made on the world’s largest tropical island. Attenborough’s long-beaked echidna (Zaglossus attenboroughi) has made an appearance despite not being recorded for 62 ...

Infant marsupials and monotremes use a connection between their ear and jaw bones shortly after birth to enable them to drink their mothers' milk, new findings reveal. Infant marsupials and monotremes ...
