Small holes in the skin or papillae with holes on the throat of some fish. Open neuromasts (genipores, cheek pores) receive vibrations from the water as it comes into contact with the body surface. Most species of fish that live in the coastal zone or near the bottom have genipores on their heads. In many predators, the lateral line is externally underdeveloped, but the seimosensory system does not suffer. For example, gobies, pike and burbot have genipores on their heads - visually distinctive holes in which an incredible number of neuromasts are concentrated.
