":Not sure. However, in any case, the distinction is very artificial and not all that useful. Some species without grooves in the fang (e.g., Rhabdophis) can cause severe envenoming just like species with grooves."
I don't speak about dangerosity. I'm just interested by the biology of teeth. ;)
I know that some opisthoglyphous can be more dangerous that some opisthoglyphous.
"There are in fact very many different arrangements of fang morphology in most "colubrid" lineages, with grooves in different parts of the fangs, or ungrooved fangs clustered together to f orm functional grooves. The distinction between aglyphous and opisthoglyphous is almost entirely meaningless."
I've the same opinion that you. Where is the limit between aglyphous and opisthoglyphous........
The "colubridae" are polyphyletic and the actually classification is really meaningless too.
":There are reports of pain, some swelling and prolonged bleding in the literature, although the "severity" (if you can call it that) is absolutely minimal. As in most colubrids, it is to be expected that most bites will be asymptomatic."
thanks to all this answer. And excuses my bad english! ;)
