Elasmobranchii (sharks and rays) > Carcharhiniformes (Ground sharks) > Hemigaleidae (Weasel sharks)
Etymology: Paragaleus: para (Gr.), near, referring to how its dentition is intermediate between Hemigaleus and the triakid Eugaleus (=Galeorhinus) (See ETYFish); longicaudatus: longus (L.), long; caudatus (L.), tailed, referring to long caudal fin equal to interdorsal distance (See ETYFish).

Environment: milieu / climate zone / depth range / distribution range Ecology

Marine; demersal; depth range 1 - 18 m (Ref. 93009). Tropical

Estimates based on models

Preferred temperature (Ref. 123201): 25.1 - 29.2, mean 27.3 °C (based on 528 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5664 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00355 (0.00144 - 0.00875), b=3.07 (2.85 - 3.29), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.2 ±0.6 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): Very Low, minimum population doubling time more than 14 years (Fec is assumed to be <10).

Fishing Vulnerability (Ref. 59153): High vulnerability (65 of 100).

Paragaleus longicaudatus (Bessednov, 1966)
