Abstract
A total of 45 seafloor sediments procured from shelf-slope region off Chennai–Cuddalore in the Bay of Bengal and analyzed for ostracod population revealed the presence of 41 species in 30 genera. Based on the results, the dominant species include Cushmanidea spp., Actinocythereis scutigera, Caudites javanus, Neomonoceratina iniqua, Spinoceratina spinosa, Stigmatocythere spp., Tanella gracilis and Lankacythere spp. Shapes, sizes and sculpture of ostracod carapaces/valves reflect the textural characteristics of substrates displaying their preference of habitats along with other ecological factors such as temperature, salinity, pH and dissolved oxygen content which seem to positively influence the abundance of diverse ostracod population at various depths.
Research highlights
-
1.
The study conducted in this region for the first time revealed the presence of 41 species.
-
2.
The ostracod population is dominantly benthic preferring sandy sediment substrates.
-
3.
Ornamentation of ostracod valves is influenced by the energy conditions prevailing in the shelf-slope region.
-
4.
Overall, environmental factors play a role in the spatial distribution of ostracods.
