Sphyrna zygaena (Linnaeus, 1758) View in CoL and Sphyrna sp.
A first individual of undetermined Hammerhead, ( Sphyrna sp. ), Sphyrnidae , was captured between 14 and 20 August 2017 by the fishing master Mr Alain Voisin on the long liner Marial from the île d’Yeu, off Arcachon (Aquitaine, Bay of Biscay, France). A second individual of Sphyrna sp. was captured on 13 September 2017 by the same fisherman and boat. It was again collected off Arcachon, at 44.650°N, – 2.217°W, at 25-30 m depth above a 1500 m deep continental slope. The specimen was estimated to weigh about 80 kg. The hook baited with sardine was hooked close to the eye. The specimen was hoist on board then returned to the sea with low survival probability according to fishermen. A third individual was captured on 14 September 2017 by the same fisherman and boat. It was again captured off Arcachon, at 44.650°N, – 2.283°W, at 25-30 m depth, above a 2000- 2200 m deep continental slope. The specimen was estimated to weigh about 70-80 kg. The hook baited with sardine was in the same way hooked close to the eye. The specimen broke loose and got away in good condition. Observations by PC. A fourth individual, identified as Sphyrna zygaena , the Smooth hammerhead ( Fig. 2A View Figure 2 ), was captured on 18 September 2017 by the fishing master Mr Rémy Descamps on the gillnetter Petit Loïc from Arcachon targeting Common sole. It was captured off Lacaneau (Aquitaine, Bay of Biscay, France), at 44.969°N, – 1.319°W, at 30 m depth. The specimen was estimated to measure about 250 cm and to weigh about 90 kg. The fisherman said he captured six or seven individuals of Hammerhead during the summer 2017. Observations by LM. As mentioned for the year 1983 by Quéro et al. (1984), records of Hammerhead shark in the southern Bay of Biscay looked higher in 2017 than usually observed. The present specimens are new records for the Bay of Biscay where the species was still uncommonly recorded.
