Merchaithrais

The Shadowhorn, or "morchaithras", is a large, flat, black ray equipped with a long, whiplike tail. Its tail is studded with short but exceptionally sharp barbs that deliver knifelike cuts and inject victims with a powerful (3rd lvl) muscle venom. The giant ray's expanded pectoral fins form triangular wings that extend along its head and trunk, giving the fish a diamond shape. The tips of these wings are equipped with (3rd lvl) electricity-producing organs that can stun (RR failure 01-75 for 1-10 rds) or immobilize (RR failure 76+ for 1-20 rds) a swimmer.

Merchaithrais prefer to swim along the bottom of the coastal shelf, burrowing themselves in the sand near shoals in order to await their prey. When waiting, their gill openings and slitlike mouths are well protected, for they are located on the rays' undersides. While swimming, they flap their pectoral fins and move gracefully mid quickly through the water, as if flying.
