Hippos "just a big river cow"

Yes, and its not only used to locate prey, but to detect any animate or inanimate object further ahead of that animal. That's why its called echolocation...the sound waves return to the animal that produced it, making an "echo".

Is this making any sense?

Very much so. Thanks for the explanation.
 
yep awesome explaination,

all and all I find it amazing the way hippos click being sooo similiar to Dolphins. :)
 
I also seem to remember Sir David Attenborough in Life on Earth (1979) saying that hippos, or at least whatever creature evolved into the hippos we know today, is very possibly the ancestor of whales.

Some genetic evidence suggest that cetaceans and hippos share a genetic link, but not all tests bear out the same result. The best way of looking at it is that a hippo ancestor and a terrestrial cetacean ancestor 'probably' share a similar ancestry. Sounds a bit vague but similar to elephants with hyrax and sirenians.
