Biogeographic distribution of Pareucalanus sewelli, a circumglobal species in subtropical-tropical waters.
This nominal species contains two distinct genetic lineages.
Solid and open circles mark sampling locations of specimens whose species identiry was verified to be P. sewelli (Atl/Ind) or P. sewelli (Pac), respectively, by DNA sequencing of 165 rRNA.
Fleminger (1973) records for P. sewelli s.l. are plotted as open squares. |

Overall Depth Range in Sargasso Sea: 0-2000 m.(Deevey & Brooks, 1977, Station "S"). For Acha & al. (2020) this species is observed on Northern shelfbreak in front of Rio de La Plata (Argentina).
See remarks in Eucalanus attenuatus, and on the doubts that subsist on certain identifications from the Indian Ocean and other place.
Uysal & al. (2002) confirm the presence of this species in the Mediterranean Sea.
According to Fleminger (1973, p.993), in relatively eutrophic regions of the Indo-Pacific, extending to the subtropical convergences, P. sewelli and P. attenuatus may co-occur and resemble one another in size and general morphology, but differences in integumental organs persist.
After T. Zuo & al. (2006) the body length is 3.75 mm; between 8 to 211 ind. m-2, present in 13 stations in the Yellow Sea-East China Sea, in autumn 2000. | | | Last update : 09/12/2020 | |
