"The hippopotamus (pl.: hippopotamuses or hippopotami), also shortened to hippo (pl.: hippos; Hippopotamus amphibius), further qualified as the common hippopotamus, Nile hippopotamus, or river hippopotamus, is a large semiaquatic mammal native to sub-Saharan Africa. It is one of only two extant species in the family Hippopotamidae, the other being the pygmy hippopotamus (Choeropsis liberiensis or Hexaprotodon liberiensis). Its name comes from the ancient Greek for "river horse".
After elephants and rhinoceroses, the hippopotamus is the next largest land mammal. It is also the largest extant land artiodactyl. Despite their physical resemblance to pigs and other terrestrial even-toed ungulates, the closest living relatives of the hippopotamids are cetaceans (whales, dolphins, porpoises, etc.), from which they diverged about 55 million years ago. Hippos are recognisable for their barrel-shaped torsos, wide-opening mouths with large canine tusks, nearly hairless bodies, pillar-like legs, and large size: adults average 1,500 kg (3,300 lb) for bulls (males) and 1,300 kg (2,900 lb) for cows (females). Despite its stocky shape and short legs, it is capable of running 30 km/h (19 mph) over short distances.
Hippos inhabit rivers, lakes, and mangrove swamps. Territorial bulls each preside over a stretch of water and a group of five to thirty cows and calves. Mating and birth both occur in the water. During the day, hippos remain cool by staying in water or mud, emerging at dusk to graze on grasses. While hippos rest near each other in the water, grazing is a solitary activity and hippos typically do not display territorial behaviour on land. Hippos are among the most dangerous animals in the world due to their aggressive and unpredictable nature. They are threatened by habitat loss and poaching for their meat and ivory (canine teeth)."

Both of these are National Geographic images Kevin! Love the yawn in #1, though it reminds me it's after midnight here and I should go to bed. :)

And I also like the combo image in #2 with the Hippo and that bird.

Thank you Jim. I forgot to mention the birds, the nearest is a Cattle Egret, Bubulcus ibis and the little one to the right is an African Pied Wagtail, Motacilla aguimp.

River horses - never really thought of them that way before. Definitely a unique critter with some interesting adaptations to their habitat. Neat shots of them and especially the last one with the egret.

Two nice mages, Kevin. I am curious about your background. Are you a biologist?
Thanks for looking and commenting Douglas, it's greatly appreciated.
No not a biologist. When I had to work for a crust I was an MRI Engineer (Magnetic Resonance Imaging) working for a large German company. Started at the beginning of MRI with just 1 system and ended up with a system in nearly every hospital. Spent a lot of time at the head office in Erlangen, Germany giving Technical support to field engineers, originally world support, but as things got bigger it was split into regions, and I worked for the European time zone. I just have a very keen interest in anything natural from plants, insects, animals and especially birds.
