They are Poison/Rock type, and are based on Glow-in-the-Dark vampire teeth and skeletons, with inspiration from the Red lipped bat fish, which walks on the seafloor with modified fins, the vampire fish, an amazonian relative of piranhas with larg lower fangs that even go through its skull, and the scorpion fish, a sea floor dwelling fish with poisonous spines on its back and is one of the most toxic fishes in the world.

Their lures, shaped like fish bones, are coated in a toxic slime that glows in the dark to atract its prey but paralyzes anything that touches them almost instantly. They would use their wing like fins to dig a hole in the sand where they can hide, leaving only their lures out in the water, their rock like skins makes them blend with stones and coral.

Hope you like them!
