Etymology: Schroederichthys: In honor of American ichthyologist William C. Schroeder (1895-1977), Woods Hole Oceanographic Institution, for his pioneering work (with Henry B. Bigelow) on cartilaginous fishes; ichthyos (Gr.), fish. (See ETYFish);  bivius: bi-, from bis (L.), two; via (L.), way or passage, etymology not explained, perhaps referring to double-valved nostrils, with incurrent and excurrent apertures. (See ETYFish).

Biologie     Fachlexikon (Englisch) (z.B. epibenthic)

A common inshore to offshore shark found on the continental shelf. Oviparous (Ref. 50449). Dental sexual dimorphism exists, with adult males having teeth at least twice as high as adult females as well as much longer and narrower mouths.

Life cycle and mating behavior Geschlechtsreife | Fortpflanzung | Ablaichen | Eier | Fecundity | Larven

Oviparous, paired eggs are laid. Embryos feed solely on yolk (Ref. 50449). Sexual dimorphism is evident in dentition of male species (Ref. 49562). Males have longer teeth with fewer cusps than females (Ref. 51093) to make 'courtship biting' more effective (Ref. 49562).

Estimates based on models

Preferred temperature (Ref. 115969): 6.4 - 15.6, mean 10.6 °C (based on 202 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5312   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.8   ±0.3 se; based on diet studies.
Widerstandsfähigkeit (Ref. 120179):  sehr niedrig, Verdopplung der Population dauert mehr als 14 Jahre. (Fec=2).
Fishing Vulnerability (Ref. 59153):  Moderate to high vulnerability (48 of 100) .
Climate Vulnerability (Ref. 125649):   (0 of 100) .
Nutrients (Ref. 124155):  Calcium = 46.4 [6.9, 193.3] mg/100g ; Iron = 0.886 [0.236, 2.484] mg/100g ; Protein = 15.8 [13.5, 19.9] % ; Omega3 = 0.215 [0.094, 0.476] g/100g ; Selenium = 24.4 [6.9, 74.1] μg/100g ; VitaminA = 10.8 [4.1, 27.4] μg/100g ; Zinc = 0.662 [0.314, 1.552] mg/100g (wet weight); based on nutrient studies.
