Naytia granulosa is a species of sea snail, a marine gastropod mollusk in the family Nassariidae, commonly referred to as the Nassa mud snails or dog whelks. [1]

Contents

Description

Naytia granulosa exhibits a moderately thick and ovate shell. The shell size varies between 16 mm and 34 mm. Its coloration ranges from pale to dark brown, often with distinctive patterns of granular ridges that enhance its structural rigidity. The aperture is ovate, with a sharp outer lip and a siphonal canal that is short but distinct. The shell’s overall structure is adapted to its habitat in muddy and sandy marine environments. [2]

Distribution

This species occurs in the Atlantic Ocean, specifically off the coasts of Gabon and Angola. Its presence is commonly associated with shallow waters in tropical and subtropical regions, where it inhabits muddy and sandy substrates. [3]

Ecology

Naytia granulosa is a scavenger, feeding primarily on detritus and decaying organic matter. Its behavior contributes significantly to the ecosystem by aiding in the decomposition process and nutrient recycling in marine sediments. The species is well-adapted to low-oxygen environments often found in muddy substrates.

Taxonomy

Originally described by Jean-Baptiste Lamarck in 1822 as Terebra granulosa, the species has undergone various taxonomic revisions. Modern molecular studies have clarified its placement within the family Nassariidae, emphasizing its close relationship to other species in the genus Naytia. [4]

Conservation

While no specific conservation measures are in place for Naytia granulosa, its habitat is vulnerable to threats such as pollution, coastal development, and habitat degradation. Continued monitoring and environmental management in its distribution range are essential for its sustainability.
