To understand physical structures in the Korean waters, we investigated the spatio-temporal distribution ofPontella species known as indicator species of water mass using a David-Hempel neuston net from April 2002 to March 2003. FivePontella species (P. chierchiae Giesbrecht,P. fera Dana,P. latifurca Chen and Zhang,P. securifer Brady andP. sinica Chen and Zhang) were found. Their abundance increased...
The neustonic calanoid copepodsPontella securifer Brady, 1883 andP. sinica Chen and Zhang, 1965 are first recorded in Korea. These species occur in high temperatures over 23 °C and in a range of salinity from 26.6 to 31.2 psu. We provide full descriptions of the two species and discuss their zoogeography.
