Facts about the platypus
The evolution of the platypus, paleontology, and taxonomy:
Water-adapted
platypus-like monomers likely evolved from more general terrestrial monomers,
and the first appearance in the fossil record of platypus-like monomers dates
back to about 110 million years ago, in the early Cretaceous period, when
Australia was still connected to South America via Antarctica, and until
recently, the Cretaceous monocot (Galmani strobodon) was placed within the platypus
family.
The living
duck-billed platypus family includes the extinct genera Monocotyledon (dating
from the Paleocene about 61 million years ago) and Obdordon (which may have
first appeared near the Oligocene and Miocene boundaries about 23 million years
ago), and a discovery in Patagonia deposits that It is 62 million years old
that the platypus was spreading across the southern continents.

Water mole behavior in water:
The platypus
hunts underwater.
It swims
gracefully by paddling with its exposed front feet and pointing with its back
feet and tail.
The folds of
the skin cover its eyes and ears to prevent water from entering.
The nostrils
are closed with a watertight seal.
In this
position, the platypus can remain submerged for a minute or Two minutes and
uses its sensitive beak to find food.
These
Australian mammals feed on the bottom,
They pick up
insects, larvae, shellfish, and worms with their beak along with pieces of
gravel and mud from the bottom.
All of these
materials are stored in cheek bags.
On the
surface, the platypus mashes food for consumption, and the platypus has no
teeth, so pieces of gravel help it chew its meal.

Water mole behavior on Earth:
On Earth, the platypus moves more awkwardly, however, the paws on its feet retract to show individual nails and allow the creature to run, and the platypus uses its nails and feet to build earthen burrows at the water's edge.

platypus venom:
The male
platypus carries poisonous glands located near its pelvis, and are connected to
hollow protrusions on its hind legs.
Young female
platypus also have these protrusions, but they lose them in the first year of
life.
The venom
glands of adult males vary in size throughout the year, reaching their maximum
size.
Its size
during the breeding season, when males use their venom to compete for mates.
To inject the
poison, the male wraps his legs around his victim and pushes the protrusions
through the animal's flesh.
The poison
itself contains a mixture of more than ten proteins belonging to three main
classes of toxins.
The poison is
not fatal to platypus or humans, but it causes excruciating swelling and pain,
and can disrupt Wound healing and cell membrane function.
In humans,
pain resulting from a platypus sting can be treated with nerve blockers،
Which prevents certain neurons
from sending
signals to the brain.

Is the platypus in danger of extinction:
The platypus
is not endangered, but the International Union for Conservation of Nature lists
the platypus as near-threatened by extinction, meaning the species may be
vulnerable to extinction in the near future but is currently ineligible as
threatened.
The platypus
was first listed as near-threatened.
In 2016 after scientists noticed a decline in the total numbers of species، Although the retreat is not well defined across the platypus range.

Conservation status:
The
platypus now still lives in the same geographical area that it occupied before
the arrival of European settlers in Australia, except for parts of the state of
South Australia from which it disappeared forever.
However,
scientists have noticed many changes in the environments inhabited by the
platypus that occurred due to human encroachments and activities. It is likely
that the numbers of the platypus have decreased somewhat over the past years
(although its historical numbers are not certain), but it is still a very
common animal in Australia.
Europeans
hunted it in new abundance until the first years of the twentieth century, out
of a desire to benefit from its valuable fur.
The platypus
has become a protected animal in Australia since 1905، However,
it continued to face severe dangers until 1950 as a result of falling into the
traps of fishermen’s nets and accidentally dying.
The platypus
now often does not face the risk of extinction, due to the success of its
rescue and conservation efforts.
This animal
still faces some dangers despite this, such as environmental changes caused by
dams, irrigation systems, pollution, fish nets, and fishing traps. The
International Union for Conservation of Nature classifies the platypus on the
Red List of Threatened Species as « species close to danger.».
In January
2020, researchers from the University of New South Wales presented evidence
that the platypus is at risk of extinction due to a combination of aquatic
development and deforestation projects.

Diseases:
It is rare
for a platypus to become infected with epidemic diseases in the wild, but there
is a general state of concern on the island of Tasmania about the spread of a
disease from one of the wild mushrooms found on the island, because it has
fatal effects on the platypus.
This disease
only affects the platypus population that inhabits Tasmania Island, and it has
not been previously documented that it is infected with the platypus in
Australia.
Symptoms of
infection with this fungus include skin rashes and skin ulcers,
Which affects the tail, legs, and
back, and these symptoms may lead to death when they multiply into
second-degree inflammation, which affects the platypus’ ability to maintain its
body temperature and obtain its food.
The
Biodiversity Conservation Branch of Tasmania's Department of Industries and
Water is currently collaborating with researchers from the University of
Tasmania to determine the risks of this disease to the platypus population on
the island, and to find out how the disease spreads and its current speed of
spread.

His fame:
Most of the
world - outside Australia - became acquainted with the platypus when National
Geographic magazine published an article about it and attempts to study and
raise it in captivity in 1939.Attempting to breed the platypus in captivity is
considered a difficult task, as only very few people have succeeded in it, most
of them in the Hesleville shelter.
In the state
of Victoria, the leading figure in these attempts was the naturalist David Flea،
Who created a aquarium that simulates the movement of streams of water
(inhabited by the platypus in nature) and succeeded in marrying waterfowl there
in 1943.
In
1972, a baby dead platypus, about 50 days old (believed to have been born in
captivity), was found in a wildlife park on the Gold Coast in Queensland.
The
Hillsville shelter succeeded - once again - in generating the platypus in 1998,
and again in 2000, in an aquarium that simulates stream currents.
Taronga
Zoo in Sydney also succeeded in generating twin platypuses in 2003, and again
in 2006.In 2020, waterfowl became a protected species under the law in all
Australian states that inhabit it, and were included in the list of endangered
species in South Australia and Victoria, and it was recommended that it be
included.
On the same
list in New South Wales.
