史丹吉氏小雨蛙下蛋
(Spawning Stejneger's Paddy Frog)

像這種卵粒型的蛙種在產卵時，經常會有特別習性，只要是沒有特別的障礙物，產卵時會以繞圈圈的方式陸續產卵，有的是順時針，有的是逆時針。這對史丹吉氏小雨蛙正在逆時針產卵，非常有趣。

In the absence of an obstacle, Stejneger’s paddy frog (Micryletta steinegeri ) spawns while moving in a circle, sometimes in a clockwise direction and sometimes in a counter-clockwise direction. Here, this Stejneger’s paddy frog is moving in a clockwise direction, resulting in a very interesting scene.
