Oxycirrhites typus Bleeker, 1857, Ambon Island, Moluccas, Indonesia.
OTHER COMMON NAMES
German: Gestreifter Schьtzenfish; Japanese: Kudagonbe.
Body slender, with an elongated snout; body whitish in color with a tartanlike pattern in red along body, snout, and dorsal fin; males larger than females within mating groups. To 5.1 in (13 cm).
Red Sea east to Panama; southern Japan south to New Caledonia.
Usually deep slope or wall habitats in seaward coral or rocky reefs, passes, and lagoons; shallow rocky reefs in southern Baja California Sur, Baja Peninsula, Mexico, and occasionally found on shallow coral reefs elsewhere, particularly in areas of upwelling. Otherwise, more common in deeper reef habitats. Usually found in gorgonians (sea fans) and black corals.
Occurs singly or in facultatively monogamous pairs on gorgonians and black corals. Will have a haremic mating system if the gorgonian or black coral is large or if others are close by.
FEEDING ECOLOGY AND DIET
Plucks small benthic and planktonic crustaceans with its long snout.
Protogynous hermaphrodites. Paired courtship and pelagic spawning just prior to or after sunset. If a male has a haremic mating group, he will move back and forth between females to court them until they spawn. Eggs and larvae are pelagic. Eggs are spherical, about 0.027 in (0.69 mm) in diameter, and hatch after 15 hours incubation at 80.6°F (27°C). The yolk sac is large, and the jaws and eyes undeveloped. Pigmentation develops with absorption of the yolk. Larvae are elongate and compressed laterally. Possess a gas bladder that is lost in adults. Specializations for pelagic life include serrations on the preopercle, a chin barbel (which disappears with growth), and the presence of cirri on the spinous dorsal fin membrane and also on the anterior nostril.
Not listed by the IUCN. Not commonly seen, despite its wide
, and population levels likely to be limited by available micro
. The collection of black corals for the jewelry trade and gorgonians for the ornamental trade poses a threat, as do unregulated harvests by the aquarium trade.
SIGNIFICANCE TO HUMANS
A highly prized aquarium species.
