Classification / Names Nomi Comuni | Sinonimi | Catalog of Fishes(Genere, Specie) | ITIS | CoL | WoRMS | Cloffa

Elasmobranchi (squali e razze) (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).

marino demersale; distribuzione batimetrica 8 - ? m (Ref. 58018). Tropical; 35°N - 34°S, 118°W - 31°W

Estimates based on models

Phylogenetic diversity index (Fonte Biblio. 82804):  PD50 = 0.5006   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00347 (0.00153 - 0.00788), b=3.12 (2.93 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Fonte Biblio. 69278):  4.0   ±0.4 se; based on size and trophs of closest relatives
Resilienza (Fonte Biblio. 120179):  Basso, tempo minimo di raddoppiamento della popolazione 4.5 - 14 anni (Fec assumed to be <100).
Fishing Vulnerability (Ref. 59153):  Very high vulnerability (90 of 100). 🛈
Price category (Ref. 80766):   High.
