RNP Platypus habitat: Turkeys Nest Dam full of coal sludge
Coal miner Peabody breached licence conditions, to pay $500,000 for Royal National Park pollution

"The Land and Environment Court found Metropolitan Mine on two occasions failed to prevent water contaminated with coal waste from flowing into a tributary of the Hacking River running through the Royal National Park, south of Sydney."

It's only recently that I have learnt that the male platypus has venomous spurs on its hind legs. Apparently the pain that these spurs can inflict on a human is excruciating, long lasting, and resistant to common analgesics .

I feel disillusioned, as I had never thought of the platypus as a dangerous animal.

This article informed me of more characteristics that make the platypus such an extraordinary creature.

Earthly Mission · The One and Only Platypus: An Egg-Laying, Venomous, Fluorescent Mammal with Electroreception—And No Stomach!The platypus is definitely one of the most extraordinary animals! It’s a mammal that lays eggs, has a duck bill, beaver tail, otter feet, and is venomous. It uses electroreceptors to locate prey, has eyes with double cones, no stomach, and 52 chromosomes. And it's fluorescent and glows under UV light!

Factors contributing directly to platypus (Ornithorhynchus anatinus) mortality and implications for conserving populations in the wild

" Based on details of more than 400 platypus deaths with an identifiable cause recorded since 1989,
five main factors contributed directly to platypus mortalities:

drowning in fish nets or enclosed crustacean traps (such as opera house traps),
being killed by predators (especially canids),
becoming accidentally hooked by recreational anglers who then cut the line,
becoming entangled in discarded fishing line or other types of litter and
being hit by motor vehicles

... Additional mortality factors included drought, severe flooding, being drawn into irrigation pumps and entrapment in manmade materials or infrastructure.

Disease was implicated as being the likely causal agent in two platypus deaths, including a female that died late in lactation.

Platypus mortalities were recorded throughout the year on the southeastern Australian mainland but peaked in early autumn, when many recently weaned juveniles are likely to be present. Given the very high number of platypus mortalities attributed to the use of fish nets or enclosed crustacean traps, their use should be banned in all waters where platypus population are known to occur.

Platypus home:
""Historic infrastructure" leaked thousands of litres of oil into a popular Tasmanian lake this month."

"Up to 30 kilometres of the shoreline of the lake, home to platypus and visited by myriad other native animals, has been affected by the spill.Tasmania has a long history of oil and fuel spills causing environmental distress in the island's waterways."

A nearly gapless #genome sequence of the #echidna, an egg-laying mammal with multiple #sexChromosomes, helps researchers to track genomic reorganization events that gave rise to a highly unusual #sexDetermination system.

related to the system of the #platypus which was the cover story in my book "Der Kuss des Schnabeltiers" / "The birds, the bees, and the platypuses." 15 years later I can't remember how that worked but I loved the story.
