I'm hoping someone can tell me what's the most extensive book available on leopard tortoises? I'd rather information on their natural history and variations than on husbandry.
Don't know of one like that. The Fife book is the best that I know of. Any other stuff that I have seen, like the kind of stuff you are after, has been in individual scientific papers. Pretty dry reading most of the time, but I've found some nice tidbits here and there. I don't have any idea how to find them now. Neal might have some links, and Jaizie, here on this forum is a master at finding that sort of thing. PM them maybe?
