The echidna , a distant cousin of the anteater, also lays eggs and is found in Australia and New Guinea. Both the platypus and the echnida are monotremes, meaning that they lay eggs and have a single opening cloaca for reproduction and elimination of wastes. Home Ocean Facts What is a platypus? What is a platypus? When not foraging, the Platypus spends most of the time in its burrow in the bank of the river, creek or a pond.
At times, the individuals use rocky crevices and stream debris as shelters, or they burrow under the roots of vegetation near the stream. Hence, the ideal habitat for the species includes a river or a stream with earth banks and native vegetation that provides shading of the stream and cover near the bank.
The presence of logs, twigs, and roots, as well as cobbled or gravel water substrate result in increased microinvertebrate fauna a main food source , and the Platypus also tends to be more abundant in areas with pool-riffle sequences.
Platypus is endemic to Australia and is dependent on rivers, streams and bodies of freshwater. It is present in eastern Queensland and New South Wales, eastern, central and southwestern Victoria and throughout Tasmania.
The western limits of the range are poorly known. Nowadays it is extinct from that state, except for the introduced population on the western end of Kangaroo Island. There is no evidence that the animal occurred naturally in Western Australia, despite several unsuccessful attempts to introduce it there.
Within its current distribution, the occurrence of the Platypus is reasonably continuous in some, but discontinuous in other catchments. Platypuses are active all year round, but mostly during twilight and in the night. During day, individuals shelter in a short burrow in bank. The activity patterns of these animals are determined by a number of factors including: locality, human activity, ambient temperatures, day length and food availability.
The Platypus feeds mainly during the night on a wide variety of aquatic invertebrates. The average foraging periods last for hours per day, and the distances the animals move during this time vary between individuals and their distribution.
The animal closes its eyes, ears and nostrils when foraging underwater and its primary sense organ is the bill, equipped with receptors sensitive to pressure, and with electro-receptors. The precise way in which the Platypus uses the bill to detect prey is still unknown, but the bill serves to find and sift small prey from the substrate, while larger prey is taken individually.
The Platypus stays underwater for between seconds, collecting the invertebrates from the river bottom and storing them in its cheek-pouches. It then chews the food using its horny, grinding plates, while it floats and rests on the water surface. Diet of the Platypus consists mainly of the benthic invertebrates, particularly the insect larvae. The species also feeds on free-swimming organisms: shrimps, swimming beetles, water bugs and tadpoles, and at times worms, freshwater pea mussels and snails.
Occasionally the animals catch cicadas and moths from the water surface. In captivity, the Platypuses are often fed freshwater crayfish Yabbies.
When swimming, the Platypus presents a low profile, with three small humps the head, back and tail visible above the water surface. The swimming action is smooth, and when the Platypus dives the back is arched as the animal plunges underwater, creating a spreading ring. These characteristics coupled with the absence of visible ears distinguish the Platypus from the dog-paddle style of the Water-rat.
Platypuses can swim through fast waters at the speed of around 1 metre per second, but when foraging the speed is closer to 0.
However, the Platpus is not well adapted for walking on land. The Platypus is largely a solitary animal, but several individuals can share the same body of water. The vocalisation has not been recorded in the wild, but captive animals produce a low-pitched growling sounds when disturbed or handled.
Young Platypuses do not seem to reproduce in their first year of life, instead, both sexes become reproductive in their second year. The eggs are then laid in the burrow, and the female curls around them to provide warmth. After 10 more days, they hatch into lima bean-sized, helpless infants.
Mother platypuses do not have nipples, but instead their milk comes from pores in their skin and collects in grooves on their stomach. Babies lap the milk rather than suck. After about four months, the babies are ready to come out of the burrow and learn to swim. Platypus venom is strong enough to kill a small animal like a dog. Meet the people trying to help.
