A species of Rhino faces extinction because they would rather fight each other than mate, according to scientists trying to save them.
There are just 80 Sumatran rhinos left worldwide and those in zoos tend to attack each other rather than pair, according to the Sunday Times.
The information comes from Britain’s Mammals Society, which also stated males are so widely dispersed in the wild that they cannot find females when it comes to mating season.
The Javan rhino is said to be in a similar state of decline with just 60 left and only two northern white rhinos survive, both of which are female.
Scientists state the only way to save some of the species could be advanced techniques such as cloning.
"These are the first steps in an ambitious project to generate northern white rhinoceros gametes from induced pluripotent stem cells.
"This would be followed by production of embryos for transfer to southern white rhinoceros surrogates. Other routes of embryo production, such as cloning, may also be an option,” said the paper in Mammal Review.
Sumatran rhinos are the smallest of the living rhinoceroses.
They are also the only Asian rhino with two horns, according to the World Wildlife Federation.
There is no indication that their population is stable while just two captive females have reproduced in the last 15 years.
