Biology of the spineless cuttlefish Sepiella inermis (Orbigny, 1848) from Mumbai waters
The relationship between dorsal mantle length (DML) and body weight (TW) of Sepiella inermis was Log TW = -2.8217 + 2.4474 log DML and Log TW = -3.1712 + 2.6808 log DML for males and females respectively. The species showed allometric growth and the regression coefficients were highly significant at...
