DSCN5256DSCN5277卵包在透明膠狀物中,半白半黑(4/17)

DSCN5281第二天早上,圓形的卵開始胚胎發育,有了頭尾及左右之分(4/18早上九點)

此時的蝌蚪若是發育較快的,就會開始往下沉,但是還是包在膠狀物質中,只是膠狀物質也呈現較為液化的狀態

 

DSCN0252同一天晚上九點,就有明顯的進展

 

DSCN0262第三天,頭尾已經成型,而且都沉到水底去了

 

DSCN0377第四天已經是具體而微的蝌蚪了。此時的胚胎已經有最基本的反射,若是去碰觸牠,就會有扭動的動作。

 

DSCN5294蝌蚪的外鰓,完全發育完成的蝌蚪就看不到外塞了。這是腹面的照片,可以看到嘴巴。
