Where
seen? This
plain stingray with a sharp pointed snout is sometimes seen on our
Northern shores, usually on muddy shores. It is more active at night
and at high tide. Small ones are sometimes also seen trapped in pools
in the seagrass meadows of Chek Jawa at low tide.
Features: Grows to about 25cm
in diameter, those seen about 15-20cm. Body kite-shaped with a pointed
snout. Body colour plain beige or pinkish without any markings. Tail
long and whip-like without markings. It does not have a skin fold
on the tail. The female has a shorter tail with a bulbous end. It
has spines on the tail which 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.
Human uses: It is harvested commercially
as a food fish. According to FishBase:
It is caught in large quantities as by-catch of bottom trawl and trammel
net fisheries |
