Abstract
The distribution, habits and ecology of Iphigenia truncata in Lagos lagoon are described. The bivalve’s response to varying salinities, temperature and dissolved oxygen content were studied. I. turncata occurs in large densities in the shallow muddy sand deposits of the Southeast of the lagoon where water currents are low. I. truncata is stenohaline, abundant in salinities between 0.5 and 23 ‰ but absent in higher salinity areas. It rarely burrows below 3.5 cm below the surface. When completely burrowed, the siphons extend about 13 mm above the sediment surface. The quiescent temperature is 42 °C.
