Every year, zookeepers at ZSL London Zoo train and coax more than 17,000 animals into stepping on the scales to be weighed and measured.

每一年,伦敦动物园的工作人员都得费尽心机让园里17000种动物走上磅秤称体重,以及接受各种测量。

The statistics are needed to ensure the animals are healthy — and to make sure they're not enjoying the easy-to-come-by food in captivity a little too much. Measurements can also help determine if an animal is pregnant, which can be vital information for conservation work of endangered species.

获得这些数据的目的是为了确保动物身体健康,同时也为了防止他们在饲养过程中吃下过多的食物。测量体重也可以判断动物是否怀孕,这些都为保护濒危物种提供了重要信息。

The information is recorded in the Zoological Information Management System (ZIMS) and shared with zoos around the world. The annual event is well-documented — and judging by these photos, justifiably so.

这些信息都会被记录在动物信息管理系统(ZIMS)里,并和全世界的动物园共享。每一年的体重测量会实况,都会以各种形式记录下来。看看下面这些照片,的确是这样。
