What is the difference between a rat and an antechinus? Tail – Antechinus have a sparsely haired tail, which is the same length as the body or shorter. In contrast a black rat's tail can be twice as long as its body and nearly naked. Ears – Many antechinus species have large thin crinkly ears that have a notch in the margin (not all species have this notch).
Antechinus are found in all states of Australia. They are native carnivorous marsupials and are protected.
