Tadpoles are the baby form of frogs. They do not develop their "sex" organs until they complete transform into a frog, so tadpoles are neither male nor female.
You won't know if your tadpole is a male or female, until they are frogs. If you have 2 tadpoles and they turn into frogs, the larger frog is a female and the smaller frog is a male. Also, males...
A tadpole that's a female will look for a male it also will swell up when it has eggs,a male will grasp the female tightly and grow black spots but there really is no way to know for sure maybe...
frog tadpoles are usually brown and cane toads are black with there mouth and nose see through but some frogs such as the green mountain frog has jet black tadpoles.Willy hahahahah TOMOZBROZ AWAY
