The great hammerhead shark, Sphyrna mokarran, is a cosmopolitan species that is caught in a variety of fisheries throughout much of its range. The apparent decline of great hammerhead shark populations has reinforced the need for accurate biological data to enhance fishery management plans. To this end, age and growth estimates for the great hammerhead were determined from sharks (n = 216) ranging in size from 54- to 315-cm fork length (FL), captured in the Gulf of Mexico and north-western Atlantic Ocean. Growth curves were fitted using multiple models and evaluated using Akaike’s information criterion. The von Bertalanffy growth model was the best fitting model, with resulting growth parameters of L∞ = 264.2-cm FL, k = 0.16 year–1, t0 = –1.99 year for males, and L∞ = 307.8-cm FL, k = 0.11 year–1, t0 = –2.86 year for females. Annual band pair deposition was confirmed through marginal-increment analysis and a concurrent bomb radiocarbon validation study. Great hammerheads have one of the oldest reported ages for any elasmobranch (44 years) but grow at relatively similar rates (on the basis of von Bertalanffy k value) to other large hammerhead species from this region. The present study is the first to provide vertebral ages for great hammerheads.

Made In

Nine new species of Prochaetodermatidae from the western Atlantic Ocean south of 35°N (off North Carolina, off eastern Florida, Gulf of Mexico, Guiana Basin, Argentine Basin) are described: Chevroderma cuspidatum, Claviderma amplum, Cl. compactum, Cl. crassum, Cl. mexicanum, Prochaetoderma gilrowei, Niteomica captainkiddae, Spathoderma bulbosum, and S. quadratum. Four species are endemics, C. cuspidatum and S. quadratum, Gulf of Mexico; Cl. crassum, Guiana Basin, and Cl. compactum, Argentine Basin. Added to those described earlier for the northwestern, northern, and eastern Atlantic Ocean and Mediterranean Sea (Scheltema 1985; Scheltema & Ivanov 2000), they complete the descriptions of all Atlantic prochaetodermatid species known to us. Two previously described species are amphi-Atlantic: S. grossum Scheltema & Ivanov, described from the eastern Atlantic, was found in the collections made in the Guiana and Argentine Basins, and Ch. turnerae Scheltema, which had already been described from the northwestern and eastern Atlantic and the Argentine Basin, was not found in the Guiana Basin material.

A New Species

A new species of squat lobster, Uroptychus atlanticus, is described on the basis of a female specimen taken at a depth of 713–841 m in the southeastern Gulf of Mexico. The new species is readily distinguished from all known species of the genus from the western Atlantic by the very spinose carapace and pereopods, and a transverse row of spines on each of the abdominal tergites 1 and 2.

Partial Revision

Five Scolelepisspecies from the Gulf of Mexico and Western Atlantic Ocean are reported and certain species previously synonymized with Scolelepis(S.) squamataare revised. Four species are reinstated: S.(S.) goodbodyi(Jones, 1962), S.(S.) minuta(Treadwell, 1939), S.(S.) acuta(Treadwell, 1914), and S.(S.) agilis(Verrill, 1873); and two are described as new: S.(S.) lightin. sp., and S.(S.) vossaen. sp. Scolelepis(Scolelepis) goodbodyi(Jones, 1962) n. comb., S.(S.) minuta(Treadwell, 1939) n. comb., S.(S.) acuta(Treadwell, 1914), and S.(S.) agilis(Verrill, 1873) are removed from synonymy with S.(S.) squamataMüller, 1806. The record of Scolelepis(P.) texanaFoster, 1971 from the Grand Caribbean region is confirmed. A key to all Scolelepisspecies from the Grand Caribbean is provided.
