Hammerhead Naga

From publisher blurb: Easily identified by its hard external skull cap, the Hammerhead Naga is a deadly reptile that uses its predominant physical feature as a weapon to bash its opponents into submission. The true threat however, lies not on its head but in its mouth. Deadly venom drips from its fangs. Those unfortunate enough to meet the inside of its maw will be the recipients of a terrible and searing pain.
