The reason why reptiles have a slower metabolism is that they're cold-blooded. But Ukanlos clearly is warm-blooded or it couldn't live in such cold environment. And who said that for warm-blooded reptiles the same rules apply as for warm-blooded mammals? Additionally Ukanlos hasn't got very much fat overall of his body (or any pelt) unlike blue whales. And the tail probably is that thick because it helps him standing on his hind legs without falling and keeping control. So it needs a bigger, heavier tail. Probably most is muscles and only a part is fat. So it still needs much food.

And that Gravios made the false decision doesn't change anything about the fact that Akantor actively attacked Gravios.
