Is this, or is this not a water buffalo?
Because the World Photographer mode doing the Photograph a Water Buffalo mission thinks it isn’t. Is this a bug?
It is a water buffalo. Specifically, the first picture is (IMO) of a water buffalo who is unamused at being photographed. 
Why doesn’t World Photographer recognise it then?
Solved! It’s an AFRICAN Buffalo. It has a separate section under the Safari bit rather than the Animals Worldwide.
Cape Buffalo Its a killer would not stand to near it. Death Toll: 300+ per year Cape Buffalo are suspected to kill around 200 people every year. They typically will charge and gore their victims. Some useless info..
