Carte de distribution de Pleuromamma scutullata par zones géographiques
Espèce Pleuromamma scutullata - Carte de distribution 2Issued from : K. Furuhashi in Publ. Seto Mar. Biol. Lab., 1966, XIV (4). [p.314, Fig.2].
Vertical distribution of Pleuromamma scutullata at four stations from the Oyashio region St. 1 (off E Hokkaido), transitional zone between Oyashio/Kuroshio regions: St. H12 (40°N, 152°E) and the Kuroshio region St. S2 (34°.5N, 141°E) and St. T-1 (30°, 142°E).
Sampling by vertical closing net in May 1964.
Espèce Pleuromamma scutullata - Carte de distribution 3Issued from : K. Furuhashi in Publ. Seto Mar. Biol. Lab., 1966, XIV (4). [p.319, Fig.7].
Vertical distribution of the water temperature at four stations from Oyashio region (SE Hokkaido) to Kuroshio region (E and SE off middle Japan).
Loc:
E Japan, off Sanriku, Kuroshio region, off SE Hokkaido, Station ''H'', Kamchatka, off SE Kuril Is., Station Knot (44°N, 155°E), Okhotsk Sea, S Bering Sea, S Aleutian Basin, S Aleutian Is., G. of Alaska, Icy Strait, Station "P", off W Queen Charlotte, Pacif. (central sub-Arctic); W Costa Rica (in Morales-Ramirez & Suarez-Morales, 2008)

Lg.:
(22) F: 4-3,6; M: 3,2-3,1; (205) F: 3,9; M: 3,25; (208) F: 4-3,9; M: 3,3; (772) F: 3,9-3,7; M: 3,3-3; (1092) F: 4,34-4,30; M: 3,76-3,72; (1096) F: 3,5-5,0; M: 2,7-3,9; {F: 3,50-5,00; M: 2,70-3,76}

The mean female size is 4.013 mm (n = 11; SD = 0.4164), and the mean male size is 3.323 mm (n = 10; SD = 0.3720). The size ratio (male : female) is 0.83 (n = 6; SD = 0.0287).
Rem.: épi-abyssopélagique. La forme identifiée sous le nom de Pleuromamma abdominalis var. scutullata dans la Mer des Sargasses par Harding, 1974 (p.145, tab.2) est sans doute une erreur.
