Schematic drawing of a generalized octolasmid (stalked barnacle) illustrating morphological characters and measurements. LC, length of capitulum; LP, length of peduncle; WC, width of capitulum; WP, width of peduncle. Scale = 1 mm.
Five species of Octolasmis found in present investigation. Scale= 1mm.
Portunus pelagicus. (A) Bar- diagram showing number of infested and non- infested crabs. (B) Pi-diagram showing percentage of infested male and female crabs. (C) Relationship between number of the octolasmids and the size of the crab. (D) Bar-diagram showing seasonal abundance of the infested crabs.
Portunus sanguinolentus. (A) Bar- diagram showing number of infested and non- infested crabs. (B) Pi-diagram showing percentage of infested male and female crabs. (C) Relationship between number of the octolasmids and the size of the crab. (D) Bar-diagram showing seasonal abundance of the infested crabs.
