Classification / Names Common names | Synonyms | Catalog of Fishes(genus, species) | ITIS | CoL | WoRMS | Cloffa

Elasmobranchii (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); corona: Latin for crown or halo, allusion not explained, probably referring to irregularly oval oculonarial expanse (See ETYFish).

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

Marine; demersal; oceanodromous (Ref. 87829); depth range 0 - 100 m (Ref. 121788). Tropical; 32°N - 19°S, 115°W - 69°W

Estimates based on models

Phylogenetic diversity index
(Ref. 82804) 		PD50 = 0.5006 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight a=0.00347 (0.00155 - 0.00774), 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
(Ref. 69278) 		3.8   ±0.4 se; based on size and trophs of closest relatives
Resilience
(Ref. 120179) 		Very Low, minimum population doubling time more than 14 years (Fec=2).
Fishing Vulnerability
(Ref. 59153) 		Moderate vulnerability (37 of 100). 🛈
Price category
(Ref. 80766) 		High.
