Distribution map of Paraeuchaeta simplex by geographical zones
|
| | | | | | | Loc: | | | Korea, Japan (Izu), Formosa Strait | | | | N: | 7 | | | | Lg.: | | | (3) F: 3,36; (63) F: 3,81-3; M: 3-2,94; (99) F: 3,45-3,15; M: 2,88-2,77; (151) F: 3,73; M: 3,45; {F: 3,00-3,81; M: 2,77-3,45}
The mean female size is 3.417 mm (n = 6; SD = 0.3168), and the mean male size is 3.008 mm (n = 5; SD = 0.2613). The size ratio (male : female) is 0.864 (n = 2; SD = 0.0113), probably ± 87 %. | | | | Rem.: | mesopelagic. 82-256 m at Station N-1 (SW Bösö, E middle Japan) from Furuhashi (1966 a).According to Tanaka, 1958 (p.338) the species is close to P. russeli. | | | Last update : 24/05/2019 | |
