Encyclopedia
Platypus, sometimes referred to as the duck-billed platypus, is a semiaquatic egg-laying mammal endemic to eastern Australia, including Tasmania. Together with the four species of echidna, it is one of the five extant species of monotremes, the only mammals that lay eggs instead of giving birth to live young. The animal is the sole living representative of its family (Ornithorhynchidae) and genus (Ornithorhynchus), though a number of related species appear in the fossil record. — Wikipedia

Science
Mammalogy is the study of mammals – a class of vertebrates with characteristics such as homeothermic metabolism, fur, four-chambered hearts, and complex nervous systems. Mammalogy has also been known as “mastology,” “theriology,” and “therology.” The major branches of mammalogy include natural history, taxonomy and systematics, anatomy and physiology, ethology, ecology, and management. — Wikipedia

- No animal alive today is 'primitive.' Why are so...on February 10, 2026 at 1:50 am
We humans have long viewed ourselves as the pinnacle of evolution. People label other species as "primitive" or "ancient" and use terms like "higher" and "lower" animals.
- Yes, feral cats and foxes really have driven many...on January 25, 2026 at 4:00 pm
Millions of years of isolation have shaped Australia's extraordinary mammal fauna into species unlike anywhere else in the world, from platypus to koalas and wombats. Tragically, Australia is the world leader in mammal extinctions.
- As puzzling as a platypus: The JWST finds some...on January 11, 2026 at 5:00 pm
The platypus is one of evolution's lovable, oddball animals. The creature seems to defy well-understood rules of biology by combining physical traits in a bizarre way. They're egg-laying mammals with duck bills and beaver-like tails, and the males have venomous spurs on their hind feet. In that regard, it's only fitting that astronomers describe some newly discovered oddball objects as "Astronomy's Platypus."
- The mechanical ratchet: A new mechanism of cell...on January 7, 2026 at 9:30 pm
Cell division is an essential process for all life on Earth, yet the exact mechanisms by which cells divide during early embryonic development have remained elusive—particularly for egg-laying species.
- Webb reveals a sample of galaxies with unusual...on January 6, 2026 at 7:42 pm
After combing through NASA's James Webb Space Telescope's archive of sweeping extragalactic cosmic fields, a small team of astronomers at the University of Missouri says they have identified a sample of galaxies that have a previously unseen combination of features.
