I read on another forum once, talktothefrog by a guy named Steven Busch or it might of been Ed Clark that you can distinguish the two sexes fairly accurate by looking at how the nose protrudes from the head. If from the nostrils down pretty much goes just straight down flat, then it's a male like how yours looks in the pictures. Females tend to protrude farther out to the end of their mouth rather then straight down. It shouldn't be full relied upon, but they said it worked with most cases of their pacmans. Wow if I saw him in those conditions I might of had to pick him up to, enjoy him .
