subadult

Meng Meng is a female subadult panda in the Beijng Zoo.She loves to play in the tree.Music: Blood on the square.

这是北京动物园雌性亚成体猫熊，常喜欢爬树。

So evidence of sustained rapid growth, even into late juvenile and subadult stages, implies that the animals in question had relatively high basal metabolic rates.

所以，即使进入幼年期与亚成体阶段，仍持续快速生据，暗示这些动物具有相对高基础代谢率。
