Where
seen? This beautiful stingray is sometimes encountered
on sandy areas and in coral rubble near living reefs on some of our
shores. It is often also seen by divers. Sadly, it is also sometimes
encountered trapped in a drift net. It is considered possibly the
most abundant ray in coral reefs in our region.
Features: Grows to about 30cm
in diameter, those seen 15-20cm. Body oval with a rounded snout. Body
colour brown, grey, yellow, olive-green to reddish brown; with lots
of obvious bright blue spots. |

St. John's Island, Aug 08 |
Tail long rather thick and broad with
two blue stripes along the length. There is a broad skin fold under
the tail, so it is sometimes called the Blue-spotted ribbontail ray.
It has one or two venomous spines near the middle of the tail.
What does it eat? The ray moves
into shallow sandy areas with the rising tide to forage for snails
and clams, worms, shrimps and crabs. As the tide falls, it shelters
in caves and under ledges. It is rarely found buried under sand. It
is more active at night.

Human uses: This stingray is harvested
commercially as seafood. It is also considered an important gamefish
for recreational fishermen. Small specimens are also taken for the
aquarium trade, although they don't do well in captivity.
Status and threats: Throughout
its range, the Blue-spotted fantail ray is under pressure from over
collection for the aquarium trade and destruction of its reef habitat.
It is considered near threatened.
