These are animals
like alligators and most turtles.
In these animals,
the sex of an embryo in a developing egg
is determined by the temperature.

crocodile
crocodile tear



ps:其實alligator 與crocodile,最大的差異點就是兩者頭部的形狀不同,alligator的頭部較寬而且嘴巴較短而圓(也就是所謂的短吻鱷,通常生活於淡水中),而crocodile則頭部較窄,嘴巴比較尖,成三角錐形(也就是所謂的鹹水鱷,通常生活於鹹水中)。
如果從側面觀看嘴型,也可以看到不同的差異,crocodile 嘴巴緊閉時,可以見到上下兩排牙齒交叉咬合,alligator嘴巴緊閉時則大部分只看到上排的牙齒。
