This communication gives an account of 18 species of benthic foraminifera collected from the Agatti Island, Lakshadweep. Out of the 18 species, 12 species belong to the calcareous imperforate group and 6 species of calcareous perforate group. Three species, viz., Quinqueloculina reticulata, Lachlanella cooki, Amphistegina lobifera are recorded for the first time from Indian waters. Six species, viz., Adelosina reticulata, Amphistegina lessonii, Neorotalia calcar, Pyrgo murrhina, Quinqueloculina auberiana and Sorites orbiculus are numerically abundant, with usual higher abundance at lower depth. Tests of the benthic foraminifera were found to have larger size possibly due to the higher availability of sunlight in the much shallower coast which preserve typical tropical oceanic conditions.

Abstract


This communication gives an account of 18 species of benthic foraminifera collected from the Agatti Island, Lakshadweep. Out of the 18 species, 12 species belong to the calcareous imperforate group and 6 species of calcareous perforate group. Three species, viz., Quinqueloculina reticulata, Lachlanella cooki, Amphistegina lobifera are recorded for the first time from Indian waters. Six species, viz., Adelosina reticulata, Amphistegina lessonii, Neorotalia calcar, Pyrgo murrhina, Quinqueloculina auberiana and Sorites orbiculus are numerically abundant, with usual higher abundance at lower depth. Tests of the benthic foraminifera were found to have larger size possibly due to the higher availability of sunlight in the much shallower coast which preserve typical tropical oceanic conditions.
