Family Dasyatidae
updated
Sep 2020
Where
seen? This sand-coloured stingray is sometimes seen on
our Northern shores, and seems particularly common on Pulau Sekudu.
It is more active at night and at high tide. It was previously known
as Dasyatis kuhlii.
Features: To about 40cm in diameter,
those seen about 15-20cm. Body kite-shaped with rounded snout. Body
colour brown to reddish brown with indistinct light blue or black
spots. The spots are edged in brown and are rather inconspicuous.
Usually has a 'mask' of darker brown across the eyes. It is thus sometimes
also called the 'Bluespotted maskray'. Tail long and whip-like with
a pale tip and dark or black-and-white bands. It has a narrow skin
fold near the tail. There is usually one spine on the tail that can
cause a painful wound by injecting a venom.
Sometimes mistaken for a horseshoe
crab and visa versa. In murky waters, these two different animals
do have a similar profile, both being round and flat with a long tail.
The Blue-spotted fantail ray (Taeniura
lymma) has bright and prominent spots and is more commonly seen
near reefs. |

What does it eat? It feeds on
crabs, shrimps and other animals that live buried in the sand.
Human uses: This stingray is harvested
commercially to be eaten, and also taken for the live aquarium trade.
It is considered one of the most commercially important rays in our
region and is trawled in large quantities in the Gulf of Thailand. |
