Gujarat is a leading maritime state in the production of marine finfish and cephalopods India. The are one major fishery resources along region having good domestic export demand. These exploited majorly by bottom trawls region. Sepia pharaonis contributes nearly 20 % to cephalopod landings Gujarat. However, reproductive biology cephalopod, poorly known from specimens for biological analysis wi...

Arginine kinase is an essential enzyme which is closely related to energy metabolism in marine invertebrates. Arginine kinase provides a significant role in quick response to environmental change and stress. In this study, we simulated a tertiary structure of Sepia pharaonis arginine kinase (SPAK) based on the gene sequence and conducted the molecular dynamics simulations between SPAK and Zn(2+...

Although cuttlefish are capable of showing diverse camouflage body patterns against a variety of background substrates, whether they show background preference when given a choice of substrates is not well known. In this study, we characterized the background choice of post-embryonic cuttlefish (Sepia pharaonis) and examined the effects of rearing visual environments on their background prefere...
