Elasmobranchii (haaien en roggen) (sharks and rays) > Carcharhiniformes (Ground sharks) > Sphyrnidae (Hammerhead, bonnethead, or scoophead sharks)
Etymology: Sphyrna: Probable misspelling of sphyra (Gr.), hammer, referring to their hammer-shaped heads. (See ETYFish);  media: Latin for middle, allusion not explained, probably referring to its oculonarial expanse being “roughly intermediate in shape between that of hammerheads [subgenus Sphyrna] and shovelheads [subgenus Platysqualus]”. (See ETYFish).

Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804):  PD50 = 0.5029   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00347 (0.00157 - 0.00767), b=3.12 (2.93 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trofisch niveau (Ref. 69278):  4.0   ±0.4 se; based on size and trophs of closest relatives
Weerstandsvermogen (Ref. 120179):  laag, minimale populatieverdubbelingstijd 4,5-14 jaar (Fec assumed to be <100).
Fishing Vulnerability (Ref. 59153):  Very high vulnerability (90 of 100).
Prijsklasse (Ref. 80766):   High.
