I saw a wildlife doco many years ago, which was set in the Amazon and although the myriad lifeforms on show did amaze, the piece of footage which is stained indelibly on my mind is that of a sloth, no, no, not the two toed, the three toed, swimming.
The question was posed earlier, "can a cow swim?". Well assuming a) it has at least four legs, and b) it's not a king tide at Killer Reef Beach, the answer is catagorically, "yes!"
This assertion is only strengthened by footage of sloth referenced earlier. If that unit can swim, any beast can swim! If that unit was in a two unit swimming race, I'd bet drcam's house on the turnip!
