Moreover, while the actual sensitivity to an EMF is known for only a few elasmobranch species, we note that at least two Atlantic species, Carcharhinus plumbeus and Sphyrna
lexvini, are able to detect an EMF in the 25-100pT range (Meyer et al.
Currently, the genus Sphyrna
is composed by nine species, with six of them occurring in Brazilian waters: Sphyrna
Los ordenes con mayor diversidad especifica son: Carcharhiniformes (59 especies), Squaliformes (24) y Lamniformes (13); a nivel de familias: Carcharhinidae (con 26), Pentanchidae y Triakidae (cada una con 11) y Sphyrnidae (7); y a nivel generico: Carcharhinus (17), Mustelus (9), Sphyrna
(7) y Apristurus (6) (Fig.
During the study, it was observed that some shark species were abundant and some were less abundant in the fish landing centers in Chittagong and Cox's Bazar districts  found the most common and widely distributed two shark species were Scoliodon laticaudus and Sphyrna
lewini which were also common in the present study.
Two shark species, Sphyrna
tiburo (Linnaeus, 1758) and Carcharhinus limbatus (Muller & Henle, 1839), which were captured only in the lower region of the bay during summer over subtidal oyster reefs and NVB habitats, were also examined.
Through its rarity, the new species, Sphyrna
gilberti, underscores the fragility of shark diversity in the face of relentless human predation.
Highly directional swimming by scalloped hammerhead sharks, Sphyrna
