Q26: Please type the answer this question  Salamander larvae basically have a body form similar to the adult-elongated body, tail, and four legs. External gills are present. Fins and balancers are present on some species. Balancers are a pair of organs on the underside of either side of the head that keeps them upright in the water. During metamorphosis the gills and fins are lost, the gill slits close, there is a modification of skin for terrestrial existence, and lungs develop. Question:  What do you notice about the development of the legs in salamander larvae. Which legs develop first?  Is this different from the anuran larvae? (please answer both parts)
