Rays & Skates

Rays and skates are cartilaginous fishes with highly developed pectoral fins blended into the body forming what is known as the disc.  Depending on the family, the disc is designed for sustained cruising or resting comfortably on the seafloor and their feeding habits reflect the primary habitat.  Mantas and Mobulas filter-feed upon zooplankton in the water column while typical bottom-feeders root for buried shellfish.  Electric Rays stun fish by swimming above them to deliver a powerful shock created by specialized muscles under the disc.  Some species defend themselves with venomous spines at the base of the tail.
