Family Callionymidae

Sep 2020
Where
seen? This
little curious fish with a flag on its back is sometimes seen on some of our Southern shores.
Elsewhere, they are considered common on shallow shetltered mud-sand
flats, especially among seagrasses. Also in estuaries and deep water.
They are usually buried during the day. Juveniles usually seen alone,
adults may be seen in pairs or small groups.
Features: Those seen on the intertidal
about 2-3cm, grows to 15cm long. A portion of the dorsal fin is large and flag-like, which
can be raised like a finger. The pelvic fins which are fan-like with
the first ray detached from the rest of the fin. Body cylindrical
and not very flat, pale with brown saddles which have bright bluish
spots. Head broad and flat with a narrow pointed mouth so that the
head appears triangular when seen from above. Fins dark, anal fins
with bright blue spots.
According to Kelvin Lim, juveniles have proportionally
taller dorsal fins with a prominent yellow edged eye-spot on the first
dorsal fin. Small juveniles around 2 cm are white with orange bars
on the head and nape.
Sometimes confused with the Fingered
dragonet (Dactylopus dactylopus). Both Fingered and Kuiter's
dragonets have the first pelvic fin ray separated from the rest of
the pelvic fin. The fingered dragonet differs in having long filamentous
rays on the first dorsal fin and distinct stripes on the second dorsal
fin.
Sometimes mistaken for flatheads (Family Platycephalidae). Here's more on how
to tell apart fish with flat heads. |
