Heh. They should switch the coding frequency for swimming ungulates with the frequency of arboreal animals preferring to climb. That way the arboreal animals would be in the trees all the time and the ungulates would hardly swim! (joking, I know, but it'd be nice if a: they'd drastically reduce the swimming frequency for most nonaquatic animals and increase the frequency of climbing for arboreal animals. Some animals, the the koala pretty much never leave a tree except to move to the next one, and its annoying to see them wandering around on the ground. And, honestly, they shouldn't have any of the primates except the Japanese maquack (spelling is not my strong suit), and the prob. monkey willingly enter water. The vast majority of primates really, really hate to get into water.
