EFFECT OF THYROXINE ON THE MORPHOMETRIC STUDIES OF TOAD, BUFO STOMATICUS

ABSTRACT

The present study deals with the effect of thyroxine on the young toads of Bufo stomaticus. The Toads were exposed to two different doses of thyroxine i.e. 10^-2 thyroxine and 10^-4 thyroxine. Experiment was conducted for 15 days. The young toads were examine for various morphometric parameters viz:- Snout to Vent Length (SVL), Head Length (HL), Head Width (HW), Diameter of Eye (DOE), Inter Orbital Space (IOS), Hand Length (HAL), Foot Length (FL), Tibea Length (TL), Leg length (LL), Arm Length (AL), First Finger Length   (FFL) and Second Finger length (SFL).The results were statistically analyzed and significant changes were observed on the selected parameters.

Key words: Toad, Metamorphosis, Thyroxine, Morphometry.
