Elasmobranchii (sharks and rays) > Carcharhiniformes
(Ground sharks) > Hemigaleidae
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).

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
= 0.5664 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00363 (0.00147 - 0.00899), b=3.07 (2.86 - 3.28), 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).
