Wild dogs are by far the most successful if you simple take the kill ratio as your norm.
But then, it may be a bit unfair, since different hunting strategies have different pro's and con's.
Just to illustrate: A failed hunt by a wild dog pack may have meant that the pack had been running at virtually top speed for two or more kilometers. Whilst a failed lion hunt may have meant that one or two individuals had an unsuccessful 50 meter dash.
Another complication is that the same species may have a different strategy in different areas. Take hyena as an example. In the Serengeti they are very active hunters, whilst in Kruger they more often scavenge.
If we take that into account, then clearly the wild dogs have a more sucessful hunting strategy if the kill rate is higher.
Analysed differently, maybe lions use less energy by only chasing for short distances so we could argue that their stragedy is more successful from and energy expenditure perspective.
It's all kinda relative.
Lion ants "dig" those conical holes and almost always get whatever happens to wander into their little cones, so we could say that they are 100% successful as well.
I think we have to take into account that once a hunt begins (from the stalk) to the concusion (either capture or escape of the prey) there are varying degrees of success for all mammals. Cats (African wild cat, and domestic cats) tend to stalk as close as possible and rely on the element of surprise which is quite often successful in relation to the energy used.
So, perhaps we need to break this down into another few threads to discuss the relative success of Cats, Wild Dogs and hyenas, Crocs, snakes, and insects.
Although certain plants (venus fly trap) are carnivorous, I doubt there are any stats available to dertermine how well they "close the deal".
DQ, are you sure of your stats there? Spider are more than 100% successful?
Conservation is not an option.
It's imperative.Leave KNP alone. Go build a hotel someplace else. Reserves are for the preservation of wildlife. Think Pink. ..
