World's Last Male Northern White Rhino Dies
The last male northern white rhino in the world has died.
Sudan was 45 years old and had to be put down after suffering "age related issues."
He was placed under armed guard in 2015 - to stop him being targeted by poachers.
The rhino also joined Tinder last year - to try to raise awareness of the plight of his species in Africa.
Now only two are left - his daughter and granddaughter.
