A new species of Calanoid Copepod from southwest Korea.


Calanoid Copepods are small (at most millimetres in length) Arthropods found living in the marine water column across the world. They are a major component of the zooplankton, and as primary consumers of phytoplankton (single-celled planktonic algae), they play an important role in marine food chains. Due to the vast numbers of these organisms found in vast marine swarms they are contenders for the most numerous group of animals; though not the most diverse or specious.

In a paper published in the journal ZooKeys on 21 November 2014, Seong Yong Moon and Seok-Hyun Youn of the Fisheries and Ocean Information Division at the National Fisheries Research and Development Institute of South Korea and Ho Young Soh of the Faculty of Marine Technology at Chonnam National University describe a new species of Calanoid Copepod from shallow waters in the Yellow Sea off the coast of Mokpo in southwest Korea.

The new species is placed in the genus Parvocalanus, and given the specific name leei in honour of Jungah Lee, the wife of Seong Yong Moon. The species is described from 21 female and 11 male specimens. The females were larger than the males, at 0.75–0.92 mm in females and 0.49–0.69 mm in males. The species was found in mixed swarms with other species of Copepods, in shallow waters with a temperature above 20˚C.

Parvocalanus leei, female, in (A) dorsal and (B) lateral views. Scale bar is 0.1 mm. Moon et al. (2014).
