I don't know why some eggs are rough-surfaced like situla's or the various racers, but I suspect it has something to do with the very dry environment they are laid in in the snake's habitat.
Thanks for all the info on your snakes. I think most of the ratsnakes comply to the slightly oval shape, with smooth surface, and vary in size as to the size of the mother. The differences I've seen come from the Asian ratsnakes that share ratsnake and racer characteristics (qualities). Several ratsnakes seem to be from a ratsnake/racer-like ancestor, like situla, porphyracea, taeniura, moellendorffi, longissima, persica, etc. The taeniura group has eggs with smooth surfaces, but they are quite hard shelled, making them somewhat different from the norm.
Looking forward to seeing more of your females and their eggs. Later...TC.
PS: The egg to the far right in my pic is a "Mandarin's", in the picture by mistake. It has a smooth surface.
>>I've never really seen the relationship in the eggs between the eggs like that. The "bumpy" appearance must come in handy to bonding nest material to the eggs and thus camoflaging them naturally, and/or keeping moisture close. Most of my eggs, being asian rat or north american rat, of course are predominately smooth surfaced, and on average oval shaped, creamish white to white, with varying sizes. So far over the past couple of years heres what I've compiled: Blue beauties-2.5-3" long, semi-slender, hatchlings average 15". Taiwans(first year so limited knowledge)-2-2.5" long, not so big around as to be round, but close, hatchling size average undetermined. Greenish ratsnake, 1.5-2" long, semi-slender, hatchlings average around 12". Miami phase cornsnake, 1-1.5" long, semi-round, although odd, hatchling size averaged 11"! Redtailed green ratsnake, 2-2.5", very slender, no hatching yet. Kunasir Island ratsnake, 2", semi-oval, no hatchlings yet. Eastern hognose, 1", roundish, 5" average hatchling length

>>Well, just thought I'd share my findings as my breeding projects and interests change each year. Like I said before, I'm planning on getting more pictures of females, pairs and hatchlings as I get them...look for more from me! Can't wait to hear others info too...(hint, hint all of ya!)
