Coastal upwelling in the south eastern Arabian Sea (SEAS) leads to oxygen depletion over the continental shelf during the summer monsoon season (June-September), with latitudinal gradients in intensity. Based on two surveys in the onset (June) and peak (August) phases of the summer monsoon, the present study evaluates the response of macrozoobenthic communities (size >500 μm) to upwelling and consequent hypoxia (dissolved oxygen <0.2 ml/l) in the central sector of the SEAS shelf (10-12°N, 30-200 m).

Article Synopsis
  • The paper reports three new records of brittle stars discovered in the Lakshadweep atolls, including Ophiarachnella septemspinosa, Ophiocoma cynthiae, and Ophiomoeris obstricta.
  • It evaluates the legitimacy of the genus Indophioderma and its species Indophioderma ganapatii, which were recently described from the same region.
  • Additionally, a checklist of 40 valid brittle star species from the Lakshadweep Islands is included, with 32 species found in shallow reef areas and 8 in deep-sea environments.
