Faune australienne


Et voilà… quelques spécimens croisés au fil de mes explorations, pour le plaisir des yeux ! D'autres à venir bientôt…

En attendant, pour vous faire découvrir quelques particularités de ces animaux, un peu d'info !

Les wombats, koalas et kangourous appartiennent tous à la même famille de marsupiaux, les Diprodontia, dont la caractéristique commune est d'être largement herbivore – même si certaines espèces peuvent manger des insectes et du miel – et, en conséquence de n'avoir que deux incisives sur la mâchoire inférieure et rien sur la mâchoire supérieure. Les second et troisième orteils de leurs pattes arrière sont partiellement fusionnés, ce qui leur permet de les utiliser pour la toilette et pour démêler leur fourrure. Certaines espèces arboricoles, comme le koala et le possum, possèdent aussi un pouce opposable sur les pattes avant, ce qui fait d'eux les seuls mammifères avec les primates à posséder une telle anatomie.

Platypus and echidna

Australia is home to the world’s only two types of living monotremes – the platypus and the echidna. Only one species of platypus exists and is endemic to Australia. There are four echidna species from whom the Short-beaked is the only one found in Australia – the other three ones exists in New Guinea.
Both platypus and echidna are egg-laying mammals, have sensitive, modified « noses » and both have exploited ecological niches that provide them with little competition from other mammals.
The similarities, however, end there. They live vastly different lifestyles and have widely discrepant body forms. In fact, so improbable is the platypus’s morphology that when the first specimen was sent to England in the late 1700s it was described as an « amphibious mole » and believed to be an elaborate hoax !
The platypus spends up to 12 hours a day in the water and is superbly equipped for its semi-aquatic lifestyle, with large, webbed feet and and sensitive bill that is able to detect the weak electrical impulses generated by moving animals. While underwater, its eyes, ears and nostrils are closed, so sweeping the long, flat bill from side to side assists it in detecting his prey. Once prey is caught, it is stored in a cheek pouch and taken to the surface, where it is ground up between horny plates on the platypus’s upper and lower jaws.
The platypus’s diet comprises invertebrates, small animals and frogs.

Short-beaked echidnas are one of the few species to be found in almost all of Australia’s varied habitats. They are covered with stiff, hollow spines – which are actually modified hairs – that help defend against predators. Echidnas survive on a diet of ants and termits and have squat, short limbs equipped with long, powerful claws for digging into termits mounds. If alarmed, they roll into a ball or quickly dig into ground.
