Summary, etc. <p style="text-align: justify;">Benthic foraminiferal abundance from three sites at Nana Layja from the coast of Kachchh was studied over a period of one year to determine the seasonal variability. All the three sites were dominated by <em>Ammonia beccarii</em> (Brunnich, 1772), <em>Pararotalia calcariformata</em> (Le Calvez, 1949), <em>Elphidium advenum</em> (Haynes, 1973), <em>Eponides repandus</em> (Montfort, 1808) and <em>Quinqueloculina bosciana</em> (d'Orbigny, 1826). These showed considerable seasonal variability at the studied three sites. The maximum total foraminiferal abundance was found on December 2016 while the minimum was observed on June 2017. <em>A. beccarii</em>, <em>P. calcariformata</em>, and <em>E. repandus</em> exhibited a seasonal pattern similar to the total foraminiferal abundance. Whereas, <em>E. advenum</em> and <em>Q. bosciana</em> showed a different pattern of abundance with the minimum and maximum abundances found in December 2016 and June 2017, respectively. Other two rare species recorded were <em>Spiroloculina </em>sp. 1 (Alcide d'Orbigny, 1826) and<em> Rosalina globularis</em> (Alcide d'Orbigny, 1826) in all the seasons. Species diversity analysis showed that the three sites are rich in species variability with a high Shannon−Weiner Index and low Evenness Index. The physicochemical characterization of seawater collected from three sites showed distinct seasonal variations.</p>
