Umwelt: Milieu / Klimazone / Tiefenbereich / Verbreitungsgebiet
Ökologie
seewasser demersal; tiefenbereich 0 - 22 m (Ref. 11892). Temperate
Southwest Atlantic: endemic to the Falkland Islands.
Größe / Gewicht / Alter
Geschlechtsreife: 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).
Body shape (shape guide): elongated.
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).
