Animals of The Australian Tropical Savanna
Saltwater Crocodile: The Saltwater crocodile is the largest of the reptiles. Saltwater crocodiles or "salties," as Australians call them, have an enormous range, populating the brackish and freshwater regions of eastern India, Southeast Asia, and northern Australia. They are excellent swimmers and have often been spotted far out at sea. They are carnivores and mainly eat small reptiles, fish, turtles, wading birds etc..., but they can also kill and eat much larger prey. They are known to take wild pigs, buffaloes, and also live stock like cattle and horses. Their prey need to adjust to this predation a common biotic factor in the Savanna.Northern Australia is a very suitable habitat because it borders the ocean and has many of the animals that they prey on.
Antilopine Wallaroo: Antilopine wallaroos inhabit savanna woodlands throughout the northern, tropical regions of Australia. During the day they reside in shaded wooded areas to avoid the hot sun. At dusk they graze in grasslands. During the cooler wet season, antilopine wallaroos may also graze during the day, but they seek shelter from rain in wooded areas.
Emu: Emus are omnivores that eat flowers, fruits, seeds, shoots, large insects, lizards, and small rodents. Emus live in grassland and desert areas in northern Australia. Emus have long necks, sharp beaks and small ears. They have two sets of eyelids, one for blinking and one to keep out the dust which is necessary because they live in the savanna. They have long feet for running and one toe on each foot that has a long talon for fighting.
Frill-Necked Lizard: Frilled lizards are members of the dragon family that live in the tropical and warm temperate forests and savanna woodlands of northern Australia. They spend most of their lives in the trees, but descend occasionally to feed on ants and small lizards. They also eat spiders, cicadas, termites, and small mammals. They are very fast reptiles which is necessary for the open savanna.
Golden Bandicoot: There are very small populations of Golden bandicoots in Northern and Western Australia. Birds are the primary threat to this species. Golden bandicoots also have to compete with rabbits for food. A golden bandicoot will nest in the hollow of a tree or on the ground; the nest is made of various plant materials. The preferred climate of this species appears to be similar to that of a tropical savanna. When the temperature rises the golden bandicoot will leave its nest and burrow in some sandy soil in an attempt to keep cool.
Purple-Crowned Fairy Wren: Purple-crowned Fairy-wrens are restricted to tropical northern Australia where they inhabit vegetation watercourses. Their nests are quite large for a fairy-wren, averaging 15.6 cm in height x 10 cm in diameter. They live permanently in long narrow territories amongst quite specific vegetation mainly along the edges of watercourses. The primary threats to populations of wrens include grazing, weeds, erosion and fire. The effects of grazing were most noticeable during the end of the dry season when cattle tended to cause significant damage to river grass stands.

Termites:
Termite Populations are an indicator species being investigated by scientists in Australia. An indicator species is a species that is referred to as the "indicator" for the rest of the Habitat or Population. They are a representation of the ecological community as a whole. |
