Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

Rückenflossenstacheln (insgesamt) : 7; Rückenflossenweichstrahlen (insgesamt) : 17 - 19; Afterflossenstacheln: 2; Afterflossenweichstrahlen: 17 - 20. The species can be distinguished from Antennablennius persicus by the following characters: number of segmented ray in dorsal fin, 17-18 (vs. 19-20 in A. persicus), anal fins 18-19 (vs. 20); white bars restricted to the ventral half and white spots on the anterior part of body (vs. white narrow bars on the anterior unspotted part of body below spinous portion of the dorsal fin); three black bars ventrally on the head (vs. with a black bar ventrally on the head at angle of mouth (Ref. 132085).
Cross section: oval.

Biologie     Fachlexikon (Englisch) (z.B. epibenthic)

Oviparous. Eggs are demersal and adhesive (Ref. 205), and are attached to the substrate via a filamentous, adhesive pad or pedestal (Ref. 94114). Larvae are planktonic, often found in shallow, coastal waters (Ref. 94114).

Estimates based on models

Preferred temperature (Ref. 123201): 23.5 - 29, mean 26.7 °C (based on 86 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5020   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00776 (0.00356 - 0.01695), b=3.00 (2.81 - 3.19), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Widerstandsfähigkeit (Ref. 120179):  hoch, Verdopplung der Population dauert weniger als 15 Monate. (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100). 🛈
