  1. Data in the same column having different lower case letters indicate significant difference (P < 0.05) among different time periods and data in the same row having different capital letters indicate significant difference between coelomic fluid and sea water (n = 3). Values are mean ± SE (n = 3)
  2. CF coelomic fluid, SW sea water
