Koalas may be right up there with nature's cutest, cuddliest creatures but things can get pretty ugly when these marsupials fight.
A video filmed in Great Otway National Park in Victoria, Australia last months shows two of the animals in a savage scrap for control of a eucalyptus tree.
One of the koalas appears to be the main aggressor and repeatedly bites the other koala on the arm. The victim screams in distress but then fights back, biting his adversary.
"We came across these two koala's fighting over territory in an eucalyptus tree," the filmer said.
"The noise was horrible and sad to witness," she added.
