Pyxicephalus Differences

[tgampper]

Hi Jeff:

I don't think we can get a definitive picture of the two species. There are many variations among populations. There are other factors to consider:

1) are we seeing hybrids?
2) some scientists are convinced that P. edulis is just a subspecies of P. adspersus
3) some scientists believe P. aspersus and P. edulis are one in the same species
4) the markings of juvenile P. adspersus and P. edulis are very much alike

It seems that there are differences between adults:

1) adspersus is larger, more widespread geographically, has a uniform green color and lack a pattern
2) edulis is smaller, more colorful and has a complex pattern, lives in lowland areas

P. a. angusticeps is highly unlikely to be found in the commercial market since they are only found in a small area of northern Mozambique.

The mystery rolls on, but I hope to get some expert answers.
