Animal Species:Tasselled Anglerfish, Rhycherus filamentosus (Castelnau, 1872)

The Tasselled Anglerfish is covered with fleshy tentacles which provides it with camouflage in its natural habitat. The species can be very hard to spot when it remains motionless among sponges and algae.

Identification

This species is brown to red above. There are dark blotches or bars on the sides separated by whitish areas extending up from below. It has a dorsal fin comprising four parts. The first is a long illicium with an esca that resembles two worms. The second and third dorsal spines are separate. These are followed by 12 to 13 soft rays.

The Tasselled Anglerfish is very similar to the Glover's Anglerfish. They can be separated by the shape of their escas and length of the illicium, which is longer in the Tasselled Anglerfish.

Size range

The Tasselled Anglerfish grows to 23 cm in length.
