Neocalanus is a genus of marine copepods. They are a dominant component of the open water ecosystems of the northern Pacific Ocean. Neocalanus are large copepods, reaching body lengths (i.e., prosome length) of more than {{convert|8|mm|abbr=on}} in Neocalanus plumchrus.

Species

There are six species:

{{columns-list|colwidth=25em|

Neocalanus cristatus (Krøyer, 1848)
Neocalanus flemingeri Miller, 1988
Neocalanus gracilis (Dana, 1852)
Neocalanus plumchrus (Marukawa, 1921)
Neocalanus robustior (Giesbrecht, 1888)
Neocalanus tonsus (Brady, 1883)

Life cycle

=''Neocalanus flemingeri'' =

Neocalanus flemingeri is predominantly annual, with a significant fraction of biennials in some areas. The largest females reach prosome length of about {{convert|5|mm|abbr=on}}; males are smaller.

Trophic interactions

Neocalanus are important food items for many predators, such as North Pacific right whale and least auklet.
