Biologie     Verklarende woordenlijst (b.v. epibenthic)

Oviparous. Distinct pairing with embrace. Young may tend to follow large objects, such as their mother (Ref. 205). Eggs are oblong capsules with stiff pointed horns at the corners deposited in sandy or muddy flats (Ref. 205). Egg capsules are 6.0 cm long and 3.4 cm wide (Ref. 41249). Frequently taken in commercial bottom hauls but not much utilized because of its small size (Ref. 5159).

Life cycle and mating behavior Geslachtsrijpheid | Voortplanting | Kuitschieten | Eieren | Fecundity | Larven

Oviparous, paired eggs are laid. Embryos feed solely on yolk (Ref. 50449). Distinct pairing with embrace. Young may tend to follow large objects, such as their mother (Ref. 205). Eggs have horn-like projections on the shell (Ref. 205).

Estimates based on models

Preferred temperature (Ref. 115969): 1.6 - 3.9, mean 3 °C (based on 42 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00513 (0.00254 - 0.01037), b=3.11 (2.94 - 3.28), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.9   ±0.7 se; based on size and trophs of closest relatives
Weerstandsvermogen (Ref. 120179):  laag, minimale populatieverdubbelingstijd 4,5-14 jaar (Fec assumed to be <100).
Kwetsbaarheid (Ref. 59153):  High vulnerability (60 of 100) .
Prijsklasse (Ref. 80766):   Medium.
Nutrients (Ref. 124155):  Calcium = 11.6 [1.7, 70.9] mg/100g ; Iron = 0.264 [0.046, 1.024] mg/100g ; Protein = 14.4 [12.8, 16.3] % ; Omega3 = 0.418 [0.167, 1.075] g/100g ; Selenium = 14 [4, 54] μg/100g ; VitaminA = 13 [2, 76] μg/100g ; Zinc = 0.331 [0.086, 1.224] mg/100g (wet weight);
