背鰭 (合計) : 7. Black spot on each side of the caudal peduncle. Males with a second similar spot behind each pectoral fin (Ref. 35388); eyes situated laterally; fully scaled; possess functioning suckers; caudal fins slightly notched (Ref. 92840).

生物学     用語集 (例 epibenthic)

Suprabenthic (Ref. 92840). Found inshore in groups around over-grown structures and among Laminaria or Zostera beds. Adults feed on small crustaceans (copepods, amphipods, mysids) and chaetognaths (Ref. 4696). Eggs are about 1 mm long, pear-shaped, and adhere to seagrass or weeds; hatch in 10 days (Ref. 4696). Pelagic larvae hatch at 2.5 mm length (Ref. 35388).

Life cycle and mating behavior Maturities | 繁殖 | Spawnings | Egg(s) | Fecundities | 幼生

Repeat spawners (Ref. 4696). Eggs are found inside hollow Sacchoriza holdfasts or other smooth substrates (Ref. 4696). Nests of care-giving males contain eggs from several females (Ref. 115238).

Estimates based on models

Preferred temperature (Ref. 115969): 8.9 - 13.1, mean 10.5 (based on 408 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 1.0000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00692 (0.00295 - 0.01623), b=3.05 (2.87 - 3.23), in cm Total Length, based on LWR estimates for this Genus-body shape (Ref. 93245).
栄養段階 (Ref. 69278):  3.2   ±0.34 se; based on food items.
回復力 (Ref. 120179):  高い, １５か月以下の倍増期間の最小個体群 (tm=1; tmax=2).
