  • Tasmanian devil b y d a v i d r a u b a
  • tasmanian devils were named by european setters after they encountered their scary screeches and seemingly ferocious nature. We know that much of their threatening behaviour is bluff their scientific name sarophilus means flesh loving these nocturnal hunters devour every part of their prey,bones,fur,everything. Since the extinction of the thylacine,the tasmanian devil has become famous for being the worlds largest camivorous marsupial.
  • what do they look like? Devils are stocky with large borad heads and short thick tails. They have black fur with white stripes aross their chaests and on their rumps they have largs pink ears,long whiskers and strong jaws with sharp teeth.Their legs are short and their claws are strong and sharp.
  • SIZE Devils are about the size of small dogs and males are slight larger then females.,Males stand up to 30 centimetres high at the sholuder and way up weigh up to number 12 kilograms.
  • WHAT DO THEY EAT? Devils are mainly scavengers feeding on dead animals. They also predators. When there is not much else to eat devils will hunt sick,injured or old prey and sometimes healthy animals too. All devils are agile and able to climb trees,dig holes and swim in scarch of food. Young devils anbush moths,tadpoles,frogs,lizards and birds.As well as these smaller mammals. Dead sheep and cattle are also eaten.
  • Devils are solitary animals but have large overlapping home ramges. They can travel up to 16 kilometers a night. Searching for food which they often shore with their neighbours. It is not uncommon to see large numbers of devols squabbling and feeding noisily on a dead animal. They are not territorial except around their dens.
  • where do they live Fossil evidence shows that tassie devils roomed widely over Australia until about too years ago. Now they live only in Tasmania where they are wide spread/having adapted to the climatic variations and wide variely of hobitats across the stale. They are found mainly in eucalypt forests coastal woodlands and heathlands but they also live around ferms and ouler city suburbs. Durring the day they shelter in their dens wich are made in hollow logs,cavers rock piles or abandoned burrows.
  • breeding and caring for young Femals breed from about 2-4 years of age mating usually takes place in march in appril each female gives birth to many been-sized young but only four successfully crawl to her rearropening pouch and attach to a teat. They spend the next 4 months drinking her milk and devaloping. Once they are fully furred they are left in the den while she forges looking for food. Young devils play-fight and practise hunting and suruival skills with their siblings. They leave their mother by late december and begin living alone normally devils live up to 5-7 years of age.
  • predators and threats On the mainland it is believed that dirgose preyed on devils and competed with them for food contributing to their disappearance. Dingose have never reached tasmania so the devils have no natural predators but young devils can be caught and eaten by wedge tailed eagles masked owls and even spotted tailed quolls many people believed devily actively hunted lambs and sheep and from 1830 onwuards they were trapped and poisoned for reward.
  • predators and threats They also suffered the effects of habitet loss and a disease that almost wiped them out in the early 1903. They were protected by law in 1941 and after that numbers increased until recently they were common,their main human threat being cars. How ever in the passed ten years a mysterious cancer has been spreading among devils from eastern Tasmainia towards the west.This disease known as devils facial tumour disase causes large lumpy tumors,on the devil’s neck and face.
  • predators and threats It also affects their teeth and stops them feeding. They usually die within 6 months. Sadly it has reached epidemic proportions. Although many scientists are desperately seeking a cure and trying to isolate healthy devils. If is fared that the species may only survive another 10-15 more years. The isolating that protected them in the past can not proect them aginst diseases hopefully they will recover.
  • WHAT IS THEIR STATUS Vulnerable.
