Seven species of galatheoid crustaceans, including five new species, are reported from the southeastern Arabian Sea, southwestern Bay of Bengal, and western Andaman Sea, India, based on material collected from 56 to 113 m depths. Distinctions between the five new species (Galathea bharata sp. nov., G. kalingasagara sp. nov., G. quadrangularis sp. nov., Nanogalathea longispina sp. nov., and Sadayoshia brevirostrum sp. nov.) and their morphological close congeners are given in detail. The genus Nanogalathea Tirmizi & Javed, 1980 is rediagnosed to include N. longispina sp. nov. Trapezionida latior Baba, 2005 is recorded for the first time from Indian waters, indicating northward extension of its known geographical range. A specimen tentatively referred to Galathea aff. nasimae Karasawa, 2019 is also reported from the Andaman Sea.

The present study provides a comprehensive overview of the taxonomic diversity of flatfish in Indian waters. Flatfish play a significant role in artisanal and commercial fisheries in India and are frequently caught as by-catch in trawling operations. However, their benthic nature makes them particularly vulnerable to the pressures of overfishing and bottom trawling practices.

This study investigates Hg, Cd, Cu, Zn, and Pb concentrations in 324 fish samples from 43 species, including two cephalopod species, in the Andaman Sea. The fish were categorized into pelagic and demersal groups. The findings revealed average heavy metal concentrations in the order: Zn > Cu > Hg > Pb > Cd, with pelagic fish showing higher levels than demersal fish.
