Swimming Krugg

The swimming krugg's third pair of legs are greatly elongated. Though the swimming krugg can still stand on them, the legs are usually used for swimming. It kicks its hind legs to swim that is somewhat similar to a frog's technique.

To feed, the swimming krugg digs shallowly with its mandibles and then nips off a piece of root. It then places the root piece in the slot formed by tiny beaklike protrusions of its snout and climbs ashore to eat. The swimming krugg can only carry one piece at a time, and is only able to eat on land. This is inefficient, but, since it is oxygen-breathing and has little capacity to hold its breath, it has no other option.

Predators include the flunejaw and the incomplete talúnuisce.
