how can ypou place a single number on all of these behaviors? Elephants
spend 80-90 % of their time in water?

Hippos forage on land, pretty much all night. 100???

here we can agree mostly, sea otters almost never get onto land

They spend a considerable time on land (and also they are the most
quadrupedal of the bears interestingly enough)

What about lemmings? 100???

There is a vast difference in how each of these animals deal with their
habitats. Placing a single number is an excercise in numbers and I doubt
bears much resemblance to what they are doing

I thought sea otters were carnivores?
What about other carnivores that aren't bipedal (e.g. mongeese (remember
meerkats?), pinipeds, otters)

> Penguins are more bipedal than other birds.
All birds are bipedal, it is a plesiomorphic feature from their ancestors
the theropod dinosaurs. But, I would argue that the penguins are very
poor bipeds and that the ostrich (a savannah animal????) is one of the best.

Even given that your premise is correct (which I do not) maybe the
causality is in the other direction? They are naked, so they like to
cool off in the water.
