Size–mass relationships for four marine nerite snails (Gastropoda: Neritidae) from the northern coast of Persian Gulf, Iran

The size–mass relationships were estimated for four Nerita snail species, viz. N. adenensis, N. longii, N. orbignyana, and N. textilis, collected from the middle and upper intertidal rocky pools of Bandar Lengeh shore line, the northern coast of the Persian Gulf, Iran, during January–April 2015. Estimates of parameter b of the size–mass relationship (W = aLb) ranged between 2.569 (N. adenensis) and 3.205 (N. textilis), while parameter a ranged between 0.0012 (N. textilis) and 0.0047 (N. adenensis). Three of four studied species (except N. textilis) revealed negative allometric relationships. Results could be useful for ecological studies and coastal management activity in future.
