The platypus is found in eastern Australia. They live aside freshwater rivers or lakes, and create burrows for shelter and protection. They are active mainly at nighttime hours, and use their webbed feet for swimming. When swimming the platypus has its eyes shut. They swim underwater for 2 minutes, before returning to the surface for oxygen. They can however stay underwater for up to 10 minutes,and due to their natural buoyancy, they need to be underneath another object to do this.
The Platypus has a wooly furred coat and range from 30cm to 45cms in length and the tail about 10 to 15 cms. The wooly furred coat actually has three different layers. The first layer keeps the animal warm, by trapping air, the second layer which provides an insulating coat for the animal, and lastly thethird layer of long flat hairs to detect objects close by. These creatures weight on average between 1 to 2.4 kilograms. They have an average lifespan of 12 years.
This lifespan may be shortly diminished, as the platypuses biggest threats are snakes, goannas, rats and foxes. Another big threat to the platypus is man, via waterway pollution or land clearing.
Platypuses feed on insect larvae, wormsor other freshwater insects. They do so mainly at night, by the use of their bill. They turn up mud on the bottom of the lake or river, and with the help of their electroreceptors located on the bill, find many insects and freshwater insects. They store their findings in special pouches behind their bill, and are consumed upon returning to the surface.
Amazing Fact: Platypuses can consume theirown body weight in food in a 24 hour period!
Male platypus are larger than the female. They reproduct by mating which occurs once a year, between June - October. The female lays between 2 - 4 eggs and incubates these for a two week period. When a young platypus is born, they feed from milk from the mother. The mother secretes this milk from large glands under the skin, the young platypus feed fromthis milk which ends up on the mothers fur.
If you thought this was a cute and cuddly Australian animal, well, you are only half correct. The male platypi have a hollow spur about 15 milimetres in length on the inside of both hind legs. This in turn is connected to a venom gland, and the platypus uses this spur to defend itself against predators.
Amazing Fact: The male platypus has venomstrong enough to can kill a small dog, or cause excruciating pain among humans.
Since only the male platypus has this venomous spur, and the gland peaks during mating season, many suggest it is normally used in aggressive encounters between other male platypus.
A baby platypus is not called a puggle, which seems to be a common misconception. There is no official name for a baby platypus, but a commonsuggested name is "platypup".
El ornitorrinco se encuentra en el este de Australia. Ellos viven a un lado los ríos o lagos de agua dulce, y crear las madrigueras en busca de refugio y protección. Son activos principalmente en horas de la noche, y usar sus patas palmeadas para nadar. Al nadar el ornitorrinco tiene sus ojos cerrados. Ellos nadan bajo el agua durante 2 minutos, antes de regresar ala superficie para el oxígeno. Sin embargo, pueden permanecer bajo el agua hasta 10 minutos, y debido a su flotabilidad natural, tienen que estar debajo de otro objeto para hacer esto.
El ornitorrinco tiene un pelaje lanudo pelaje y van desde los 30cm a 45cms de largo y la cola de 10 a 15 cms. El pelaje lanudo pelaje en realidad tiene tres capas diferentes. La primera capa guarda el animalcaliente, atrapando el aire, la segunda capa que proporciona una capa de aislamiento para los animales, y por último la tercera capa de pelos largos planos para la detección de objetos cercanos. Estas criaturas de peso en promedio entre 1 a 2,4 kilogramos. Tienen una vida media de 12 años.
Esta vida puede ser poco disminuida, ya que el ornitorrincos mayores amenazas son serpientes, goannas, ratas y...
