"All the names I know from nurse:
Gardener's garters, Shepherd's purse,
Bachelor's buttons, Lady's smock,
And the Lady Hollyhock.

Fairy places, Fairy things,
Fairy woods where the wild bee wings,
Tiny trees for tiny dames.
- These must all be Fairy names !"

"In the high society of the first half of the century, marriage, despite it's bestowal status upon the wife, was the most absurdity. Marriage, conferring instanteous rank or money, ... lost most of its prestige and moment right after the wedding. ...By the end of the century, spurred by Rousseau's moralistic Nouvelle Hèloíse, a contrary cult, that of virtue, arose. After 1770 conjugal and maternal love became not merely admissible, but, for some, moral imperatives. ...

[...]
...Rousseau, who sought for himself the crown of morality in ostensibly defending marriage, presents in his Nouvelle Hèloíse the most enticing and extended defense of illicit love ever penned. The root of the problem is that as the century progressed sensibility became confused with morality: passionate feeling, if expressed in a highly civilized mode with grace and nuance, makes us forgive the Rousseau of The Confessions, for example, his pettiness, his jealousies, his betrayals. This moral-amoral byplay, present already in the novels of Richardson, was to be more intense as the century unfolded."

"...As the social contract seems tame in comparison with war, so fucking and sucking come to seem merely nice, and therefore unexciting. ... To be 'nice', as to be civilized, means being alienated from this savage experience - which is entirely staged. [...] The rituals of domination and enslavement being more and more practiced, the art that is more and more devoted to rendering their themes, are perhaps only a logical extension of an affluent society's tendency to turn every part of people's lives into a taste, a choice; to invite them to regard their very lives as a (life) style." - Susan Sontag , on 'Fascinating Fascism' (-74; p 103;104-5 at Under the sign of Saturn)

Species Endangered (MS-Series from) IV / 09


(The) Platypus

  • Class: Mammal
  • Order: Monotremata
  • Latin name: Ornithorhynchus anatinus
  • Range: Australia (East coast / Tasmania / Kangaroo Island)
  • IUCN Status: LC / Cites: -


(2009 situation).



Duck-billed Platypus is a famous example from the more obscure looking creatures in nature. But it's not just a popular attraction, Platypus also has long evolutionary history reaching the earliest days of mammalians. In fact, it's perhaps the most archaic mammalian alive and sole member in its own animal genus. Platypus has been known more widely since late 19th century, and often mentioned is also the story from how it became known to science: When receiving the bodies of the platypus specimen scientists by first look assumed it to be a typical creations by animal taxidermists of the time, and not a real species at all. Later, so goes the story, a researcher had to be sent to find out whether this odd creature also really reproduced by laying eggs. But that was the actual truth; The eggs are hatched 2 weeks before the young Platypus are born. A rare feature among mammalian but more typical for reptiles - only other mammalians in existence that lay eggs are (also the only extant monotremes) Echidna-species; Long-beaked Echidnas(Zaglossus bruijini) and Short-beaked Echidnas(Tachyglossus aculeatus) that live in New Guinea, latter also is found on Australian environments.



From its other strange features, Platypus beak is quite different from that of the birds. It's actually a soft leathery 'antenna', supplied with nerve-endings (feeding opening below the beak). Platypus-beak even senses small electrical activity which helps the animal locate the small insects/prey it needs to feed. Male specimen of them have certain spurs which contain a 'mild' venom (powerful enough to kill a dog), also less typical feature for mammalian. But they also have more typical characteristics, fx. the young specimen are fed with milk (although that practice also has certain details only found on Platypuses).


These various mentioned specialties make Platypus such exceptional case that EDGE (Evolutionary Distinct and Globally Endangered - an organization specializing in the species 'unique' or distinct from the evolutionary perspective and/or poorly-known and therefore in danger of quietly slipping towards extinction unnoticed), includes Platypus in the Top 100 list from mammalian species most in need of protection (...and why not also check Platypus situation on their list, since EDGE's-fact sheet actually has more coherent data and information than we're presenting here.)


Platypus is basically a small carnivore. It eats little animals mostly found from its freshwater habitat; crustaceans, insects (worms and larvae, fx), also small fish and frogs includes the diet. Much of their life and habitat goes in water (for a platypus needs enough nutrients to keep body temperatures warm and so it spends about half the day in search of food) - and is well adjusted to waters like one can see from our picture catching the species in its natural element. On the ground, partly due its strange body proportions and characteristics, animal looks rather clumsy and much less well-mannered, perhaps. But, here's then a video from Arkive showing Platypus around its nest on river-bank:





Earlier, like in the case of many animals with fur, also Platypuses was extensively hunted – especially in the 19th century, when thar caused their disappearance from most of the earlier range in South Australia. Nowadays its found at country's eastern parts, as an aquatic species mostly on rivers and such environments. It's natural hostiles earlier included only Australian native water rats, but nowadays also some typical human introduced co-threats include also fx cats and dogs that may harm and kill Platypuses. Pollution in the rivers as well can troublesome their survival in several ways. Not least is the problem from waste chemicals, which can destroy the natural oils that keep animals dense fur waterproof. Secondly, it is also been noticed that fx things like relative acidity of water affect the species breeding success. So, Platypuses are sometimes mentioned as 'flagship species', because protecting its habitat also benefits whole eco-system where it lives. Famous Platypus captive-breeding program ('Platypussary', so called Platypus-tank invented by David Fleay) is been established since about mid last century, although only some specimen have succesfully been able to raise in captivity. Also, conservation practices nowadays include platypuses being introduced for the Kangaroo island on South Australia coast.


Interestingly as well, 'this peculiarity', originates from the earliest evolutionary divergence of mammalians, in fact its mentioned as the only (mammalian) species left alive which may date back to the pre-mammalian times, as far as the age of reptiles (means over 65.5 Million years [Ma] to the past). Also researches from recent times have showed that platypus genes, that support the egg-laying, do have some reptilian characteristics. According to that, its genome is only from 80 per cent typically mammalian features, but the rest contains elements similar to earliest forms of birds and modern reptiles as well as its own unique genetic elements (or about so, read more from it in this blog-post at EDGE). Animals 'similar' (/closely so) as the current Platypuses are only found from fossils about 100 000 years before the present, but extinct resembling monotremas found from Australia (Teinolophos / Steropodon) are known from much older times. Indeed, it's even speculated that likely its kind of species was present at the time of super-continent Gondwana, about 160 Ma past. This is based on finding of a creature comparable to Platypuses (Monotrematum sudamericanum) from the fossil record of S.America (from about 60 Ma past). It (nowadays) seems to be believed little younger than the oldest Australian (fossil) finds and is only known from few teeth-remains, but in those times a land bridge between the continents via Antartica still existed (before the Antarctica became colder like it is nowadays, and also finally cutting that connection, about as little as 33 Ma ago - see the situation of land-masses in that period from Scotes.). Anyway, in the earlier studies the living monotremas, Echidnas and Platypus are also noticed more related for each other(having diverged about 50-60 Ma), and marsupials and the 'modern' placental mammals more related by genetic structure (the former having diverged from monotremas as far as 160-180 ma past according to DNA), therefore also supporting presumption from monotremas 'branch' being the most earliest/distant (surviving) mammalians. Not surprising then, that Richard Dawkins's book (2004) Ancestor's Tale (A Pilgrimage to the Dawn of life), starting from present and extending to earliest pasts, presents Platypus on one of it's chapters - in the mentioned period(180 Ma) and as the oldest mammal 'narrator' included.


Possibly, the Platypuses (in those times soo long ago) were more common and spread for various other places around the world. In this (instance) we don't need to go that far, but can just as well perhaps imagine period somewhat closer to our times, some 40-50 million years ago (Eocene). So, let's think about Platypus swimming in that habitat, similarly as it does nowadays – and this almost gives us a strong feeling from that the evolution, how random to human observer (it may seem), is never a one-way-street. Because it really is some sort of miracle, (lucky coincidence) that this particular peculiar-looking creature still exist.

But, having not quite accurate, or approximate knowledge from the Australian ecology or animals in those early times, and even less from the vegetation, what will follow is only very applicable view. Its meant just to give us some fun (can be read like some Hollywood-kind history, say). We therefore take some likely aspects from those times and freely imagine the rest, whether or not all these species even lived in during that particular place and time (since we weren't around to witness any of this, and actually most is based on descriptions about European fossil fauna from Messel ; 'Middle Eocene Eden'):


"The climate is probably warmer and more humid, and there's lot more CO2 in atmosphere than today, released by the volcanic eruptions in the preceding geologic boundaries before this period of time. After the mentioned series-of-incidents and as consequence (during some millions of years) the tropical forests have enlarged for the most common and widespread vegetation all over the world. Humans won't be around for several (tens) millions of years, but here's many other highly diversified mammals living in these ecosystems. And, (since we're supposedly in Australia, nowadays known also from having the most archaic ecology and faunas) we can imagine our Platypus-like creature inhabiting a large pond closer to some swamp-side where also exists some giant frogs, a meter tall or so, (possibly relics from the more distant past already, but Platypus should be careful, they eat smaller mammalians too). Then we can likely except to see some large (2 meters in height) flightless birds like Diatrymas, carcass eaters, that as well can threaten our Platypus on the grounds. But, also we might perhaps find more familiar species like crocodiles not too much differing from their present forms. There's marsupials of course, also carnivorous and some resembling the existing genus of marsupial cats - like Dasyurus Albopunctatus(NT), found on New Guinea today - only this Eocene fauna includes lot more similar species and probably several of them considerably larger, too. And other animals, some such distant and strange that we can't probably here invent suitable counter-parts from the currently existing species.

Perhaps also bats, regularly with a 40-50 cm wingspan. And ants about the size of a palm. Beetles and cockroaches close to that as well, equally huge if compared to current average. And perhaps those aquatic insects that our 'Platypus' searches from the bottom of the waters are also larger in size (probably our particular species is as well). So, all these live at varying distances from Platypuses own nesting burrows, plenty of other co-species, some of them more or less predatory. Therefore this not necessary is more 'comfortable' environment for it than the one in present times ... But there it goes(!) ...smoothly diving in between the waters, reaching the lakes bottom and continuing its own particular doings, much the same way as nowadays..."(likely), ...or about so...
