platypus : a small carnivorous aquatic monotreme mammal (Ornithorhynchus anatinus) of eastern Australia and Tasmania that has a fleshy bill resembling that of a duck, dense fur, webbed feet, and a broad flattened tail — Webster
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.
The unusual appearance of this egg-laying, duck-billed, beaver-tailed, otter-footed mammal baffled European naturalists when they first encountered it, with some considering it an elaborate hoax. It is one of the few species of venomous mammals: the male platypus has a spur on the hind foot that delivers a venom capable of causing severe pain to humans. The unique features of the platypus make it an important subject in the study of evolutionary biology and a recognizable and iconic symbol of Australia; it has appeared as a mascot at national events and features on the reverse of the Australian twenty-cent coin. The platypus is the animal emblem of the state of New South Wales. — Wikipedia

Drug pollution concentrates in stream bugs,...

Sixty-nine pharmaceutical compounds have been detected in stream insects, some at concentrations that may threaten animals that feed on them, such as trout and platypus. When these insects emerge as flying adults, they can pass drugs to spiders, birds, bats, and other streamside foragers. These findings by an international team of researchers were published today in Nature Communications. […]

on September 4, 2018 at 1:50 pm
A team of researchers with The University of Queensland has found evidence suggesting that mammalian brain hemispheres had a means of communicating long before the development of the corpus callosum. In their paper published in Proceedings of the National Academy of Sciences, the group describes mammalian brain studies they conducted using MRIs and what they found. […]
