There is a world somewhere between reality and fiction. Although ignored by many, it is very real and so are those living in it. This forum is about the natural world. Here, wild animals will be heard and respected. The forum offers a glimpse into an unknown world as well as a room with a view on the present and the future. Anyone able to speak on behalf of those living in the emerald forest and the deep blue sea is invited to join.
Well, I think If we talk in general scenario, These evidence should be accounted as Lion predation on Rhinos.
To my understanding, Every predator on earth attack and feed on weaker animals, whether he is old, sick, calf or injured. They do this not only with bigger prey but also with their regular or smaller prey. This is law of nature.
Since Lion are capable of bringing down Rhino, elephant and hippo (old, injured, smaller, sick etc) We can say that they prey on them. On the other hand Leopard, Cheetah etc can not attack these weaker giants so we can not account them.
Lion as the social animal can prey largest animal which other carnivore can not. Lions have 2 advantage
1. They are one of the top powerful predator on earth
2. They are social animal
Some predator may outcompete Lion in 1st point mention above with marginal difference but when we add the 2nd point they are way ahead.
Now, similarly some other social animal may have better and more powerful social structure than lion but when we add point 1 they become better predator.
