More on author: Richardson.
Environment: milieu / climate zone / depth range / distribution range
Ökologie
seewasser demersal; tiefenbereich 0 - 22 m (Ref. 11892). Temperate
Southwest Atlantic: endemic to the Falkland Islands.
Size / Gewicht / Alter
Maturity: Lm ? range ? - ? cm
Max length : 9.3 cm TL Männchen/unbestimmt; (Ref. 11892)
Rückenflossenstacheln (insgesamt): 3 - 4; Rückenflossenweichstrahlen (insgesamt): 21-25; Afterflossenweichstrahlen: 16 - 19. Reddish-olive with very large brown blotches (Ref. 11892).
Common in the littoral zone, under rocks, but may occur to depths of 40-50 m (Ref. 5191). Accorded full species recognition because of the presence of tubular cephalic pores and a single knob bearing a tentacle above each eye, thus setting it apart from the other species (Ref. 5191). Feed on small crustaceans and common in littoral of all sub-Antarctic islands (Ref. 42041).
