The world’s last male northern white rhino has died.
The rhino was named Sudan and lived at the Ol Pejeta Conservancy in Kenya. He was 45 years old.
Sudan had been ill for months and was eventually put to sleep after getting much worse.
His death means there are only two of this type of rhino left alive in the entire world.
They are both female – and are Sudan’s daughter and granddaughter.
Why is this kind of rhino so rare?
Rhinoceroses are the second-largest land mammal after elephants.
There are around 20 thousand southern white rhinos living in the wild. But the northern rhino is critically endangered – with just two now left.
Poaching for their horns meant that white rhinos were almost wiped out in the 1970s and 1980s.
The last few wild northern white rhinos in the Democratic Republic of Congo were killed around 15 years ago in the early 2000s.
The World Wide Fund for Nature reported that the northern white rhino was extinct in the wild in 2008.
