GROWTH OFOCTOLASMIS COR(AURIVILLIUS, 1892) ON THE GILLS OFSCYLLA SERRATA(FORSKAL, 1755)

Abstract
A unique experimental procedure to determine the growth of Octolasmis cor used to advantage the suspended crab cage operation in the Straits of Johore, Singapore. This allowed growth measurements of a previously inaccessible symbiotic organism in a natural situation. The resulting data suggest that growth to sexual maturity is rapid, occurring within a two-week period. It is speculated that this is an adaptation to an ephemeral substrate which allows O. cor to maximize its reproductive capacity by increasing egg production and the number of potential hosts.
