Large tadpoles

Could these be toad tadpoles? They are much bigger than the other tadpoles which I recognise as frog tadpoles. Not further on in development - just bigger

| Annie, if you want to compare, have a look at a photo of two toad tadpoles I posted, the thread is 'newts, frogs & toads - photos'. I think their proportions are different from frog tadpoles, very fat round body with a comparatively thin tail, whereas the frog tads are more gently tapered. |

| I have noticed big variation in sizes of my frog tadpoles, of the same age. I presume this is partially due to feeding, but probably individual differences between their genetic loading from the parents. Toad tadpoles are black, and not the brindled colour that frog tadpoles are once they are a bit more rounded. Depending upon temprature, frog tadpoles will continue to stay tadpoles for longer and become bigger as well. Even to the point of not metaphorphising until the following year! I guess they have a set temprature point when it is safe to develop out of the water, so they stay in until the environment is right. There was a frog at the zoo (some exotic variety) called the 'paradoxical frog'. Loved the name--but it wasn't called that because of a contrary nature, it was due to the fact that it's tadpole state is much bigger than it's frog state. Whopping big tadpoles, yet the frogs were half it's size! |
