Temperate and sub-Arctic North Atlantic Ocean. Range extends south of the English channel to the Alboran Sea in the Mediterranean.

As differences between species are very subtle, for general morphological description, see genus diagnosis.

Female:
Cephalothorax stocky in lateral view, cephalosome strongly tapered anteriorly, barely protruding anteriad of the rostrum. Posteroventral margins of the first 2 thoracic segments without or with very short spiniform processes. Posteroventral margin of the 3rd thoracic segment is convex and smoothly rounded. The mediodorsal surface of one or more abdominal segments 1-3 with a short sensillum and integumental pore. Seminal receptacle small. The ratio of the lengths of the 1st and 2nd basipodites of P4 is less than 1.5.

Female: 0,91-1,77 mm
Male: 0,91-1,37 mm

Morphological differentiation between species of Pseudocalanus is very ambiguous, identification bordering impossible in juvenile stages. Adult P. elongatus can be distinguished from other species of the genus by the anteriorly tapered cephalosome.
