Marsupial torpor differs from non-marsupial mammalian (eutherian) torpor in the characteristics of arousal. The Tasmanian devil is the largest surviving carnivorous marsupial. Marsupial reproductive organs differ from the placental mammals. They share a similar fauna which includes marsupial and monotreme mammals and ratite birds. No mammals that are marsupial or monotreme are kosher. The mountain pygmy possum is a small rodent-like marsupial. It is named after the wombat, a marsupial indigenous to Australia. The planigale is a small carnivorous dasyurid marsupial native to Australia. The first American marsupial the Europeans encountered was the common opossum. In marsupial and placental mammals, copulation occurs through the vagina. Other names include banded anteater and marsupial anteater. He was one of the first to describe the Australian marsupial, the wombat. The Tasmanian devil ("Sarcophilus harrisii") is a carnivorous marsupial of the family Dasyuridae. The common brushtail possum is perhaps the most widespread marsupial of Australia. They include representatives of placental, marsupial, and multituberculate mammals.
