Short description Identification keys | Morphology | Morphometrics

Snout cylindrical. Pectoral and caudal fins present. With 13-15 bony plates between head and dorsal fin (Ref. 35388). Caudal fin somewhat angulous, diamond shaped (Ref. 59043).

Coastal and estuarine waters (Ref. 126547); often found on sandy shores among floating or attached seaweeds (Ref. 6733). Ovoviviparous (Ref. 205). The male carries the eggs in a brood pouch which is found under the tail (Ref. 205). Spawns in summer. Young are sometimes caught pelagically in the North Sea (Ref. 35388).

Estimates based on models

Preferred temperature (Ref. 123201): 9.4 - 12.5, mean 10.7 °C (based on 317 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00024 (0.00013 - 0.00043), b=3.24 (3.09 - 3.39), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.7 ±0.40 se; based on food items.

Generation time: 1.5 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (K=0.75).

Fishing Vulnerability (Ref. 59153): Low vulnerability (19 of 100).
