Chlorophthalmus agassizi Bonaparte, 1840

A Shortnose greeneye, Chlorophthalmidae ( Fig. 3I ), was collected on 23 Oct. 2018 during the EVHOE survey, using a bottom trawl. It was collected at Station W0544 (Southern Bay of Biscay, France), at 45.2815 / 45.2597 °N, –3.2791 / –3.2550 °W, at 500.6/ 508.4 m depth. The fresh specimen measured 167 mm TL, 149 mm FL, 135 mm SL, 37 mm HL. This specimen was preserved with the collection No. MNHN-IC 2020-0090 and a tissue sample was preserved under No. BPS-4225. Recorded by S.P. Iglésias. The species was first recorded in the Bay of Biscay in 1998 but no specimen preserved and no Station No. recorded ( Quéro et al., 1999). Two additional specimens, 16 and 14 cm TL, were recorded in the Bay of Biscay on 17 and 28 Oct. 2002 at 44.5833N, – 2.1333W and at 46.2833N, – 4.2667W, 332- 360 and 416-418 m, respectively ( Quéro et al., 2003b). Another specimen 204 mm TL was also recorded on 4 Nov. 2010 in the Bay of Biscay at 46°60N, – 4.91W; 490- 452 m at Station O1013 ( Iglésias, 2011). This species can now be considered as established in the Bay of Biscay and its northern range expansion may be related to warming waters as a consequence of climate change.
