Head and 1st pedigerous somite fused, 4th and 5th separated by indistinct suture. Genital segment rather broad in relation to length; lateral part of posterior margin sometimes armed with row of minute spinules, lateral surface with cluster of spinules on either side, anterior and dorsal to spermatheca.

Paracalanus quasimodo density (inds. m3).
Samples collected monthly on days of full moon at Cabo Frio, Brazil (23.8° S, 42.018 °W) from January to December 2011, by horizontal hauls (1 m depth).
The dominance of P. quasimodo was due to its emphasis on herbivory (R2 = 0.83) and lead to a decrease in the planktonic diversity (R2 = 0.63).
The results revealed that predation by carnivorous copepods , like Corycaeus spp. and Oncaea spp, is the main opposing factor affecting P. quasimodo dominance (R2 = 0.70 |

The mean female size is 0.857 (n = 3; SD = 0.1290) and the mean male size near of 0.82. The size ratio (male : female) is more or less of 0.957. The sex ratio (female: male) is 1. | | | | Rem.: | Reported mistakenly from the Western Mediterranean in Ounissi & Khelifi-Touhami (1999, p.10).
Certain confusions are possible between this species and P. parvus or P. indicus.
The presence of this species in San Francisco could have been by introduction in ship's ballast waters, like in the Sino-Japanese waters.
After Rosa J.C.L. & al. (3016, p.71), this species has been cited as one of the most abundant species in coastal waters of Brazul, and mentioned as indicative of cold water. | | | Last update : 12/02/2021 | |
