Hello, everyone

I've tried taking the initiative to become a more active member of this site, only being apprehended by my studies and by my lack of expertise and topic ideas. However, I just remembered a question that's been on my mind for some time:

Do you have a recommendation for literature regarding the care and/or life habits of frogs of the genus Ceratophrys?

Most of what I've learned of horned frog care comes from my studies of biology and zoology (I'm a biology major at Henderson State University in Arkansas), researching scholarly articles (and not-so-scholarly) on the web, and, perhaps most pertinent of all, the expertise of the very helpful members of this forum. That being said, I'm very open to suggestions on informative literature on horned frogs, particularly the species C. ornata, C. cranwelli, and C. cornuta. Being a student in uni, money is no object when it comes to buying literature (particularly after having to buy over $200 worth of human anatomy and physiology texts), so feel free to recommend anything from the free literature online to hard copies of texts written by specialists.

As always, I appreciate any and all feedback!

Kyle
