Rays Trivia Quiz – Gliders of the Sea

Rays are flat-bodied fish with cartilage skeletons, closely related to sharks. There are over 600 species, including stingrays, manta rays, eagle rays, electric rays, skates and sawfish, living in oceans and some rivers.

Rays swim by flapping or rippling their wing-like pectoral fins. Many live on the seafloor and breathe through openings on top of their heads. Stingrays defend themselves with venomous tail spines, and torpedo rays can deliver electric shocks.

Manta rays are gentle filter feeders with the largest brains of any fish. Overfishing, bycatch and the trade in gill plates threaten many rays, and sawfish are among the most endangered marine fish.
