Distribution map of Pleuromamma scutullata by geographical zones
|
| | |  Issued 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. |
 Issued 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) | | | | N: | 33 | | | | 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.: | epi- to abyssopelagic. The identified form under the name of Pleuromamma abdominalis var. scutullata from the Sargasso Sea by Harding, 1974 (p.145, tab.2) is without doubt an error.
For Ferrari & Saltzman (1998, p.220), females differ from P. robusta by anterior edge of genital segment , viewed laterally, not as vaulted, with a low hump on ventral edge posteriorly;, copulary pore located about half the distance between anterior and posterior edge of genital complex; A1 with pronounced attenuate points on segments 1 and 2; exopod 3 of P5 without lateral denticles. Males differ from P. robusta by urosomal segment 2 ventrally with a small area of spinules posteriorly on left side and laterally a small area on the right side; urosomal segment 3 ventrally with small areas of spinules posteriorly on left side and laterally areas of denticles on right side; tip of distal rigid seta of segment 14 of left A1 does not reach to the base of a distal attenuation of the segment; left exopod 2 (proximal) of P5 medial triangular attenuation not twisted, right basis without denticles, exopd 3 (middle) medial attenuation smoothly curved.
After Sedova & Grigoryev (2010, p.12) the features as the shape, size, and direction of teeth in proximal segments of A1, the presence of protuberances on the thorax and the armature of P5 are insufficient for species identification. | | | Last update : 15/02/2019 | |
