> Ovalentaria/misc (Various families in series Ovalentaria) > Plesiopidae (Roundheads) > Acanthoclininae
Etymology: Acanthoclinus: Greek, akantha = thorn + Greek, klinein, kline = sloping and bed, due to the four apophyses of sphenoid bone (Ref. 45335); marilynae: Named after Marilyn Hardy (Ref. 9003).

Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

Rückenflossenstacheln (insgesamt) : 19; Rückenflossenweichstrahlen (insgesamt) : 4 - 5; Afterflossenstacheln: 10 - 12; Afterflossenweichstrahlen: 3 - 5. Head and body mottled light to dark brown to deep chocolate brown throughout. Fin membranes greyish brown to black with tips of dorsal and anal fins white or orange. Distinguished from other rockfishes in having 10-12 spines in the anal fin.

Adults are common in the subtidal zone but may be found in rock pools. Feed on small fishes such as triplefins (Ref. 9003). Eggs are guarded by the male parent (Ref. 205).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00457 (0.00180 - 0.01158), b=3.10 (2.87 - 3.33), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.7 ±0.61 se; based on food items.

Widerstandsfähigkeit (Ref. 120179): mittel, Verdopplung der Population dauert 1,4 - 4,4 Jahre. (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
