Seasonal variation of Chaetognaths in the coastal waters off Kori, was studied. Samples were collected monthly during the period from March 1988 to February 1989 at 30 stations. Ten species belonging to three genera were identified: Sagitta crassa, S. nagae, S. enflata, S. minima, S. regularis, S. robusta, S. neglecta, S. ferox, Pterosagitta draco and Krohnitta pacifica. Mean abundance of chaetognaths changed monthly from 0 to 165 individuals m^-3. The predominant species varied with month; Sagitta crassa occurred abundantly from April to July, S. enflata from August to November and S. nagae occurred throughout the year except for March.
