Hi,
can anybody tell if the pictured specimen is truly a Lachesis muta? Looks like a preparation, so eyecolor must not be the real one.

If I take a look at the distance from the pits to the eyes, the squamation especially the eyeshield, and generally the shape of the head it does not look like a Lachesis muta for me.
Maybe someone can give a hint.
MfG,
Roland
