There's three basic species of zebra, mountain zebras, Grevy's zebras, and plains zebras.

斑马有三个基本品种，山地斑马、细纹斑马和平原斑马。

The Grevy's zebra is larger than a standard plains zebra and has narrower stripes and wider ears.

细纹斑马比标准的平原斑马大，条纹更窄，耳朵更宽。

" It's a serious threat to us, " said Andrew Letura, an animal observation officer at Grevy's Zebra Trust (GZT).

细纹斑马信托组织（简称GZT）的动物观察官员安德鲁·勒图拉说：“这对我们来说是一个严重威胁。”

Drought has killed about 40 Grevy's since June - which is how many would be expected to die over a whole year, said Letura.

勒图拉称，自6月以来，干旱已经造成约40匹细纹斑马死亡，这一数字是往年预计一整年内细纹斑马的死亡数量。
