国际树懒日

今天是国际树懒日,让我们都慢下来,感受下树懒整日懒洋洋的生活吧。如果你想实际体验下,可以去外面找一棵树,把自己倒挂上去。不过你可没法像树懒一样一直挂在那里,因为它们一生中的大部分时间都在做这件事。他们的胳膊、腿、手和脚都进化得适应悬挂,就像今天照片中的这两只霍氏树懒。

霍氏树懒属于二趾树懒,说是“二趾”,但其实是“二指”:它们的双臂(前足)仅有二趾,但后足上有三趾。尽管同在热带雨林中享受慢生活,两趾树懒和三趾树懒却是远亲。今天这张照片拍摄于哥斯达黎加的一个海边小镇。照片中的母子俩虽然亲密,但它们不会永远在一起,因为树懒“最好的生活”就是独居。成年树懒很少和别的树懒打交道,不过,有时候雌性树懒会在一起挂着玩。

Hoffmann’s two-toed sloth

Hoffmann’s two-toed sloth, also known as the northern two-toed sloth, is a species of sloth found in the rainforests and deciduous forests of Central and South America. True to their stereotype, they live a slow-paced life and are one of the world’s slowest mammals. They sleep between 15 to 20 hours every day. Their arms, legs, hands and feet evolved for hanging out of trees like the pair of Hoffmann's two-toed sloths in today's photo.

The mother and child in today's photo are relaxing together in a coastal town of Costa Rica. They won't be together forever, though, as they prefer a solitary life. While gestation lasts 11.5 months, newborns are precocial and are usually capable of hanging upside down on their own between three to five weeks after birth. After around a year they go out on their own, and adult sloths rarely interact with one another.
