The lemupus has replaced its ancestor because of better heat regulation. They have developed a sail for absorbing heat. Their fur is much thicker now, to keep them warmer in the alpine (they have a million hairs per square inch). They still sleep in dens (that they dig) with arctic plants as bedding.
They hunt in the trees, but will battle a rival troop on the ground on their back feet. Because they are semi-arboreal they can support larger groups of 18 to 24. Their males are 96 cm tall while their females are 76 cm tall. They are much stronger and even hunt down super-large creatures like crymaids and karyowees. To catch flying white-backed plents they will throw rocks at them to knock them out of the sky. Because of these advancements they now also live in the tundra.
