Abstract

Two species of Portunid crabs namely Portunus pelagicus and P. sanguinolentus were examined for the presence of octolasmids which belong to four species; namely Octolasmis angulata (Aurivillius, 1894), O. cor (Aurivillius, 1894), O. lowei (Darwin, 1851), and O. tridens (Aurivillius, 1894). Number of infested P. sanguinolentus was 114 (10.8% of the total P. sanguinolentus) while total number of octolasmids hosted by these crab was 5165. The average number of octolasmids found in the right and left gill chambers was 17.74 ± 37.22 S.D and 16.26 ± 38.85 S.D respectively, which is not different significantly (t = 0.265, α = 0.05). In P. pelagicus, 188 octolasmids were found in the gill chambers of 48 infested crabs. The average number of octolasmids found in the right and left branchial chambers was 2.38 ± 3.1 S.D and 1.54 ± 2.0 S.D, respectively, which is not significantly different (t = 1.48; α = 0.05).
