Batfishes
Family Ephippidae
updated
Feb 11
Where
seen? The fishes with long fins are sometimes seen, in
seagrass meadows, near reefs and at jetties on our Southern shores.
What
are batfishes? These fishes belong to Family Ephippidae.
According to FishBase:
the family has 7 genera and 20 species, found in the Atlantic, Indian
and Pacific Oceans. Those recorded for Singapore belong to Platax
sp.
Features: The body is flattened
sideways. The mouth is small. Adults are silvery and rather squarish.
Hence their other common name of Spadefish. Juveniles may look very
different in colour and pattern and have very elongated dorsal and
anal fins. Those seen 12-15cm long usually with two dark bars, one
through the eye, on an orange body. The species are difficult to distinguish
without examination of small body parts.
In some species, the juveniles are found with feather
stars (Class Crinoidea). Others may lie on the side, floating
in the water to mimic leaves or flat against the surface mimicking
toxic flatworms.
May be confused with the Silver
moony (Family Monodactylidae).
What do they eat? They feed on
seaweeds and small animals.
Human
uses: Juvenile batfishes are often taken from the wild
for the aquarium trade.
Status and threats: None of our
batfishes are listed among the threatened animals of Singapore.
However, like other creatures of the intertidal zone, they are affected
by human activities such as reclamation and pollution. Over-collection
by hobbyists can also have an impact on local populations.
