Environment: milieu / climate zone / depth range / distribution range
Ecology
Marine; brackish; demersal; depth range 1 - 96 m (Ref. 86376), usually 1 - 50 m (Ref. 35388). Temperate; 8°C - 24°C (Ref. 4944); 66°N - 20°N, 18°W - 42°E
Eastern Atlantic and Mediterranean Sea: throughout North Africa from Cape Blanc, Mauritania north and eastwards to the Suez Canal; also along the eastern Atlantic coast northwards to Trondheim (Norway) and Baltic Sea. Also known from the Black Sea (Ref. 4646).
Length at first maturity / Size / Weight / Age
Maturity: Lm ?, range 6 - ? cm
Max length : 18.0 cm TL male/unsexed; (Ref. 35388); max. reported age: 5 years (Ref. 97194)
Neck scaled with a black spot in the front end of each dorsal fin (Ref. 35388); body shape is terete, slightly depressed; eyes situated dorso-laterally; reduced swim bladders (Ref. 92840).
Found in estuaries, lagoons and inshore waters over sand or mud, in seagrass or on algae (Ref. 4696). Occasionally recorded in freshwater, but there are no documented records of actual occurrence in European freshwaters (Ref. 59043). Feed on crustaceans (larger amphipods, isopods, shrimps, mysids, small crabs), bivalves, gastropods, polychaetes, chironomid larvae, sometimes small fish (Ref. 4696).
Repeat spawner (Ref. 4696). Male guards eggs.

Estimates of some properties based on models
Preferred temperature (Ref.
115969): 8.3 - 18.8, mean 10.8 (based on 1296 cells).
Phylogenetic diversity index (Ref.
82805): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00851 (0.00656 - 0.01104), b=3.08 (3.04 - 3.12), in cm Total Length, based on LWR estimates for this species (Ref.
93245).
Trophic Level (Ref.
69278): 3.3 ±0.2 se; Based on diet studies.
Resilience (Ref.
69278): Medium, minimum population doubling time 1.4 - 4.4 years (K=0.19-0.3; tm=0.8-2; tmax=4).
Prior r = 0.71, 2 SD range = 0.31 - 1.65, log(r) = -0.34, SD log(r) = 0.42, Based on: 4 K, 2 tgen, 2 tmax, 2 Fec records
Vulnerability (Ref.
