A smaller cousin of the mantas with a slender, whip-like tail, the spinetail devil ray is a fast, schooling filter-feeder of open and coastal waters. It is famous for spectacular breaching — launching clear of the surface and belly-flopping back with a loud slap. Often seen at the surface, sometimes alongside mantas.

Conservation context
Endangered — gill-plate fisheries and bycatch; extremely low reproductive rate.
IUCN · Endangered
Watch responsibly
Don't chase or crowd schools; keep distance and let them feed and pass undisturbed.
Field notes
Devil rays make spectacular synchronized leaps, breaching several feet into the air.
One of the deepest-diving rays known, and a prolific breacher — the reason for the leaps is still debated.
