The Nashville Zoo is also celebrating the birth of a male red ruffed lemur named Helios.

纳什维尔动物园还在为一只名为赫利俄斯的雄性红围脖狐猴庆生。

Living ruffed lemurs specialize in eating fruit.

现存的颈狐猴专门吃水果。

A cruise tour will take passengers for a close look at animals such as golden monkey, ruffed lemur and capybara amid the croaking of frogs.

乘船游览时，乘客会在青蛙的呱呱声中近距离观察动物，如金丝猴、斑狐猴和水豚。

And ruffed lemurs can swallow seeds that are more than 30 millimeters around -- bigger than an American quarter!

环颈狐猴可以吞下直径超过 30 毫米的种子——比美国 25 美分硬币还大！

And in the past, there was a giant relative of the ruffed lemurs called Pachylemur that might've helped disperse those seeds.

在过去，有一种叫做 Pachylemur 的皱褶狐猴的巨型亲戚可能帮助传播了这些种子。

And at about three or four times the size of living ruffed lemurs, it could've easily taken on those really big seeds.

它的体型大约是现存的颈狐猴的三到四倍，很容易就能吃掉那些非常大的种子。
