Paracalanus parvus explained

Paracalanus parvus is a copepod found throughout the world, except the Arctic.

Description

The female P. parvus usually ranges from about 0.6mm1.3mm in length, and the male is usually between about 0.5mm1.4mm in length.

Distribution

P. parvus is nearly cosmopolitan, found in waters throughout the world, with the exception of the Arctic.^[1]

Ecology

Life cycle and reproduction

P. parvus breeds continuously,^[2] although its abundance and egg production rate vary seasonally,^[3] with it being abundant from April to December.^[4] Its egg production rate is positively correlated to temperature and concentrations of chlorophyll a.^[3]
