Elasmobranquios (tiburones y rayas) (sharks and rays) > Myliobatiformes (Stingrays) > Aetobatidae (Pacific eagle rays)
Etymology: Aetobatus:Greek, aetos = eagle + Greek, batis, batidos = a ray (Raja sp.) (Ref. 45335); narutobiei:Named for its common name in the Japanese waters ‘Naru tobi-ei’ (pronounced ‘Nar-oo-tobee-ay’), Naru’ referring to Naru Island and ‘Tobi-ei’ the Japanese name used for eagle rays which translates to black kite (a bird); noun in apposition. Eponymy: Though it looks as if it could be an eponym, the binomial combines ‘Naru’ (Naru Island, Japan) with ‘tobi-ei’ – the Japanese name for eagle rays. (Ref. 128868), visit book page.

Descripción breve Claves de identificación | Morfología | Morfometría
This medium to large-sized Aetobatus (reaching 150 cm DW) possess the following diagnostic characters: uniformly greenish grey to brownish dorsal surfaces, without pale spots or ocelli; long head, ventral length 27.4-31.9% DW; long to very long rostral lobe (longest in adult males) and narrow, tapering evenly to tip; single row of teeth plates, those in lower jaw chevron-shaped; width of lower tooth plate about 2.4 times its width and in about 18 series; 100-104 pectoral-fin radials (excluding propterygial radials anterior of eyes); 88-90 total vertebral centra (including synarcual); pelvic-fin radials 1 (with 2-5 fused elements) +17-18; males mature by about 80 cm DW; born at 33.4-35.2 cm DW (Ref. 94821). Body shape (shape guide): other (see remarks); Cross section: flattened.
Found in shallow waters at water temperature above 15-17°C; in winter months, the species leave the shallower bays for nearby sea where water temperature is above 15°C brought by the Kuroshio current-derived warm waters (Ref. 94821).
