The most notable mammal present is the endemic Kangaroo Island Kangaroo (Macropus fuliginosus fuliginosus), the icon for whom the island was named upon European discovery in 1802. A smaller marsupial present on the island is the Tammar Wallaby (Macropus eugenii). An endemic dasyurid is the Critically Endangered Kangaroo Island Dunnart (Sminthopsis aitkeni), which is found only in the west of the island in Eucalyptus remota/E. cosmophylla open low mallee, E. baxteri low woodland or E. baxteri/E. remota low open woodland. The Common Brush-tailed Possum (Trichosurus vulpecula) is a widespread folivore native to Australia.
Monotremes are also represented on the island. There is also an introduced population of the Duck-billed Platypus (Ornithorhynchus anatinus) in the western part of the island in Flinders Chase National Park. The Short-beaked Echidna (Tachyglossus aculeatus) is also found moderately widespread on Kangaroo Island.
Chiroptera species on Kangaroo Island include the Yellow-bellied Pouched Bat (Saccolaimus flaviventris), which species is rather widespread in Australia and also occurs in Papua New Guinea. Australia's largest molossid, the White-striped Free-tail Bat (Tadarida australis) is found on Kangaroo Island. Another bat found on the island is the Southern Forest Bat (Eptesicus regulus), a species endemic to southern Australia (including Tasmania).
Several anuran species are found on Kangaroo island: Brown Tree Frog (Litoria ewingii), Spotted Marsh Frog (Limnodynastes tasmaniensis), Painted Spadefoot Frog (Neobatrachus pictus), and Brown Toadlet (Pseudophryne bibroni), in addition to the Brown Froglet (Crinia signifera).
The Heath Monitor (Varanus rosenbergi ) is a lizard that grows up to a metre in length, preying on smaller reptiles, juvenile birds and eggs; it is frequently observed on warmer days basking in the sunlight or scavenging on roadkill. The Black Tiger Snake (Notechis ater) is found on Kangaroo Island. Another reptile particularly associated with this locale is the Kangaroo Island Copperhead (Austrelaps labialis).
The Glossy Black Cockatoo (Calyptorhynchus lathami) is found on the island, especially in the western part, where its preferred food, fruit of the Drooping Sheoak, is abundant. The Kangaroo Island Emu (Dromaius baudinianus) became extinct during the 1820s from over-hunting and habitat destruction due to burning.
Marine mammals that are observed on the island include the Australian Sea Lion (Neophoca cinerea) and New Zealand Fur Seal (Arctocephalus forsteri), each species of which is native to Kangaroo Island, and abundant at Admiral's Arch as well as at Seal Bay.
Kangaroo Island is not so adversely impacted by alien species grazers as parts of the mainland. No rabbit species are present on the island, and introduced (but escaped) Domestic Goats (Capra hircus) and pigs (Sus scrofa) have generated only minor issues. However, a Koala (Phascolarctos cinereus) population introduced to the island in the 1920s has caused significant damage to certain woodland communities, especially to Manna Gum trees.
Crinia signifera és una espècie de granota que viu al sud d'Austràlia.[1]
Es reprodueix després d'un aiguat independentment de quina sigui l'època de l'any.[1] La posta és una massa gelatinosa d'uns 150 ous que adhereix a la tija de les plantes aquàtiques o a les roques.[1] Al cap de 10 dies en surten els capgrossos i en tres mesos ja han completat la metamorfosi.[1] Els adults viuen gairebé sempre a l'aigua i s'adapten a ambients aquàtics molt diversos (des de tolls enfangats a rierols de muntanya).[1]
Els mascles fan uns 2,5 cm de llarg i les femelles una mica més.[1]

The common eastern froglet (Crinia signifera) is a very common, Australian ground-dwelling frog, of the family Myobatrachidae.
The common eastern froglet ranges from southeastern Australia, from Adelaide to Melbourne, up the eastern coast to Brisbane. It also inhabits a majority of Tasmania. It is one of the most commonly encountered frog species within its range, due to its ability to occupy several habitat types.
The common eastern froglet is a small frog (3 centimetres), of brown or grey colour of various shades. The frog is of extremely variable markings, with great variety usually found within confined populations. A dark, triangular mark is found on the upper lip, with darker bands on the legs. A small white spot is on the base of each arm. The dorsal and ventral surfaces are very variable. The dorsal surface may be smooth, warty or have longitudinal skin folds. The colour varies from dark brown, fawn, light and dark grey. The colour of the ventral surface is similar to the dorsal surface, but mottled with white spots.
The common eastern froglet will call within a large chorus of males close to a still water source, or slow flowing creek. The call of the male is a crik-crik-crik; this is heard all year round, during wet and dry conditions. An average of about 200 eggs are laid in small clusters attached to submerged vegetation. The tadpoles and eggs survive in 14–15 °C water. Tadpoles are normally brown and reach about 36mm in length. Development is relatively short and dependent on environmental conditions. At a temperature of 15 °C development can range from 6 weeks to more than 3 months. Metamorph frogs are very small, about 8 mm.
The diet of the species consists of small insects, much smaller in comparison to their size than most frogs.

Crinia signifera est une espèce d'amphibiens de la famille des Myobatrachidae[1].
Cette espèce est endémique d'Australie. Elle se rencontre dans tout le Sud-Est depuis Adélaïde jusqu'à Brisbane et en Tasmanie[1],[2]. Elle est présente jusqu'à 1 000 m d'altitude. Il s'agit d'une espèce terrestre très abondante.
Crinia signifera mesure 30 mm. Sa coloration est brune ou grise avec différentes nuances. Les dessins sont très variables d'une grenouille à l'autre même dans un même territoire. La lèvre supérieure porte une marque triangulaire noire et elle a des bandes sombres sur les pattes postérieures. On trouve une petite tache blanche sur la base de chaque patte avant. La surface dorsale peut être lisse, rugueuse ou avoir des plis cutanés longitudinaux. La couleur varie du brun foncé, au fauve, au gris clair et foncé. La surface ventrale à la même couleur que le dos mais est tacheté de blanc.
