Animal Species:Yellow Crested Weedfish, Cristiceps aurantiacus (Castelnau, 1879)
The Yellow Crested Weedfish usually occurs in areas of seaweed. Its behaviour and colouration make the species hard to observe.
Standard Common Name
Yellow Crested Weedfish
Crested Weedfish, Golden Weedfish
The Yellow Crested Weedfish has a tall first dorsal fin that originates in front of both the eye and the supraorbital tentacle. The second dorsal fin has a long base. There is often a gap between the second last and third last dorsal fin rays. The colouration of this species can vary from brown to yellow or orange, sometimes with touches of pink. Juveniles are paler and may have faint bars.
Three species of Cristiceps are recorded from Australia. The Crested Weedfish, Cristiceps australis, has a lower first dorsal fin that originates over the eye (not in front of it) and behind the supraorbital tentacle. The Silverside Weedfish, Cristiceps argyropleura, has a triangular first dorsal fin that is attached to the second dorsal fin by a membrane.
The species grows to 18 cm in length.
