Anybody in need of, or know an individual in need of a topic for their biology dissertation? (hey- possible paper-publication here...)

Pacman's seem to be a great candidate for reclassification (original Genus was described in 1824).

Ceratophrys Cranwelli (Genus/specie) by definition would only be able to breed with (and have viable young) other Ceratophrys Cranwelli (and sub-species of).
If, as I understand it, a "samurai blue" is a cross between Ceratophrys Cranwelli and Ceratophrys Ornata, then they should be grouped as sub-species in a new species category (Ornwelli ?)- whereas Ceratophrys Cornuta- wich is unable to produce viable offspring when crossed with another variant (resulting in "fantasys") would be correctly placed in it's current taxonomical position.

I always found this topic intriguing when I bred Lichanura Trivirgata and Labeotropheus Trewavasae/Fuelleborni.
