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 ...
At birth, pygmy hippos weigh 4.5–6.2 kg (9.9–13.7 lb) with males weighing about 0.25 kg (0.55 lb) more than females. Pygmy hippos are fully weaned between six and eight months of age; before weaning they do not accompany their mother when she leaves the water to forage, but instead hide in the water by themselves. The mother returns to the ...
On land, a hippo can easily outrun a human — and in the water, they are nearly unstoppable. Hippos are also social animals who are rarely ever alone. ... But beyond their sheer size and ...
Sharks have one of the highest for fish alongside manta rays (although the electrogenic elephantfish has a ratio nearly 80 times higher—about 1/32, which is slightly higher than that for humans). [14] Treeshrews have a higher brain to body mass ratio than any other mammal, including humans. [15] Treeshrews hold about 10% of their body mass in ...
Size comparison between the human brain and non-primate brains, larger or smaller, might simply be inadequate and uninformative – and our view of the human brain as outlier, a special oddity, may have been based on the mistaken assumption that all brains are made the same (Herculano-Houzel, 2012).

The pygmy hippo was born on February 19 weighing 15.4 pounds. He's just a baby! This is the first time a pygmy hippo has been born in Athens' Attica Zoological Park 10 years.
Size comparison between a human and two species of Basilosaurus, B. cetiodes (dark blue) and B. isis The heaviest archeocete , and possibly the heaviest known mammal was Perucetus , with weight estimated at 85–340 t (84–335 long tons; 94–375 short tons), while length is estimated at 17.0–20.1 meters (55.8–65.9 ft), [ 110 ] possibly ...
The species exhibited size variability, with individuals from the late Early Pleistocene and Middle Pleistocene being smaller on average than those from earlier in the Early Pleistocene. [4] In comparison to modern Hippopotamus amphibius , the skull is more slender and elongate, but with a shorter neurocranium . [ 5 ]
