Wow! That is a lot of information to process. You have got me interested in this experiment now; I'm curious to find out what type of behavior they will display during phonotaxis. I predict the males will only vocalize in test A like you, but that's just my opinion and we'll soon find out right

? Since they're secretive and the males don't display territorial dominance, wouldn't it be logical they only vocalize during breeding season in the right weather conditions? That's weird if they do vocalize in Test C for the different type of genres of music though.
I really think you should write up a care sheet proposal on these guys, not only was your introduction concise and legible... It also got me interested in the project even though I'm not very fond of these frogs. Even though they're not very popular in the pet trade and not readily available; I still think it would be a cool care sheet to read over and get information on this secretive species. There's always room for more, right? Like for another pacman maybe for you to do a vocalization experiment with them.
Anyways, good job... Ready to hear the results.
