Both laemanctus and corytophanes are corytphanidae....even though they look so different.
Laemanctus are cone heads and corytophanes are helmeted iguanas or forest chameleons.
There are...I think...3species of forest chameleons...2 of which are egg layers and one is a live bearer.
Laemanctus...I think... are all egg layers but one species might reproduce by parthenogenesis.
I say "I think" about some of the things because there may be more species/subspecies of them since I studied them...and I'm not sure about the parthenogenesis having been proven.
@Klyde O'Scope ...sorry that I derailed your original topic.
I'll quit now.
