Development of mouthparts in the tadpoles ofRana tigrina Daud
- 32 Downloads
The morphology of the mouthparts ofRana tigrina tadpoles is studied. The development starts after hatching with distinct mouth opening and is followed by paired beaks and labial fringes. The horny teeth then start differentiating in both the labial fringes and by addition of successive rows of teeth the full complement of larval dentition is developed. The mouthparts persist upto stage 50 and by stage 51 both the beaks and teeth are shed and the labial fringes are considerably resorbed.
