subadult

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

这是北京动物园的雌性亚体猫熊萌萌，她非常喜欢爬树。

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，即使进入幼期与亚体阶段，仍持续快速生长的证据，暗示这些动物具有相对高的基础代谢率。
