Short description Chiavi di identificazione | Morfologia | Morfometria

Spine dorsali (totale) : 7; Raggi dorsali molli (totale) : 10; Spine anali: 1; Raggi anali molli: 9. Characterized by generally pale grey to yellowish body color; about six slightly diagonal bands on body; head with orange spots; usually with one or more black spots on first dorsal fin; variable coloration of fins; first dorsal fin, fan like; united pelvic fins, frenum present; longitudinal scale series 33-37; head without scales; greatest depth of body 3.9-4.4 in SL; rounded caudal fin, about equal to head length (Ref. 90102).

Occurs in silty coastal bays (Ref. 9710). Enters estuaries (Ref. 4343) and freshwater tidal zone habitats (Ref. 12693). Found on muddy bottom at the base of the reef at Toguan Bay, Guam. Uses the burrow of a mottled brown alpheid prawn with two or more short white saddles or spots. Lives coastal sand and mud habitats from shallow estuaries to moderate depths on slopes (Ref. 48637).

Estimates based on models

Preferred temperature (Ref. 115969): 25.9 - 29.1, mean 28.3 (based on 818 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00708 (0.00333 - 0.01504), b=3.09 (2.92 - 3.26), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.0 ±0.65 se; based on food items.

Resilienza (Ref. 120179): Alto, tempo minimo di raddoppiamento della popolazione meno di 15 mesi (Preliminary K or Fecundity.).

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

Price category (Ref. 80766): Very high.

Mahidolia mystacina (Valenciennes, 1837)
