Abstract
A research on the seasonal activities of medusae was conducted from January 1999 to September 2000 in Enoshima-Shonan Port located at the innermost corner of the Sagami Bay. The research confirmed nineteen species of hydroid (HYDROZOA), one species of box jellyfish (CUBOZOA), and three species of scyphomedusae (SCYPHOZOA). Four species of comb jellies (CTENOPHORA) were also confirmed.
