; subclass Elasmobranchii, order Rajiformes)
A small family of marine fish that, because of their elongate bodies, tend to resemble sharks, but the gill clefts are in a ventral position, as in other rays. Typically, members of the family have a long, flat snout with blunt and equal-sized teeth along the edges. They are common in all tropical seas and estuaries. There are about six species, distributed world-wide.
