Tadpoles ?

[herpdoc]

Thanks, I thought these might be bullfrogs but was not sure. I was hoping they were leopard frogs. Are green and leopard frog tadpoles smaller?

bullfrog tadpoles are generally larger than leopard or green frog tadpoles but there isn't a huge difference in size and there can be some overlap (ie a really big mature green frog tad can be larger than a mature bullfrog tad). the way to distinguish them is by appearance. the biggest difference is when the tadpoles are more mature you can see dorsolateral lines in green frog tads and bullfrog tads are smooth. in general bullfrog tadpoles tend to be have rounder, fat bodies with taller dorsal tails while green frog tadpoles have much flatter bodies, have flatter tails. bullfrog tadpoles tend to have fine dots whereas green frog tadpoles tend to have a more random color pattern. i'm not very familiar with leopard frog tads but i think they tend to look more like green frog tads and have those rectangular body markings.
