In Reply to: Anyone else ever noticed round snouts in captive Elaphe? posted by chrish on January 29, 2003 at 01:18:56:
I have noticed this also. I have always attributed it to availability of food. My assumption has been, in the wild more of the available nutrition goes to the vital organs (the head being one) and less to the overall size mass of the snakes as those CB with a weekly feeding schedual. It could also perhaps be that they develop larger heads in order to consume larger prey items, rather than the vital organ hypothesis.
Just my assumptions, no actual research or proof. Interesting topic though.
TravisG with new web site, just started it today though so doesnt have much yet http://www.angelfire.lycos.com/extreme4/naratsnakes
:I have wondered about this before (maybe here?). I see pics of Elaphe obsoleta on this site all the time and in books etc.
:I often notice that cbb Elaphe have much more rounded, shorter rostra than wild caught snakes. I was looking at the bairdii posts a couple of pics down and noticed it again. Wild-caught snakes seem to have long elegant heads, captive snakes have rounded almost Pituophis like heads.
:To see what I mean, compare the shape of the bardii head two posts down to the shape of this bairdi (or obsoleta x bardi?) head on a wild caught snake.
:Anyone else ever notice this?

:(P.S. - I won't use Pantherophis yet, not because I don't believe in the validity of the N.American lineage, but because I hate that name!)
