Description

The shell of an adult Jagora asperata can be as long as 50–80 millimetres (2.0–3.1 in) and has a width of about 18 millimetres (0.71 in). This shell is solid, dark brown to yellowish brown, highly tower–shaped, comprising up to twelve whorls. The apical whorl is truncated. The sculpture of the shell shows closely spaced axial ribs and spiral elements with tiny nodules.

The body of these snails is gray to black with filiform antennae. They are characterized by a unique reproductive system, including a long sperm gutter, a very short a spermatophore bursa and a prominent lateral ridge working as a seminal receptacle. Females carry eggs and juvenile stages within their mantle cavity. These snails feed on detritus and algae.

Distribution and habitat

This species occurs in the northern part of the Philippines, on Luzon, Leyte Island, Samar Island and several other small islands. They live in small mountain rivers with stony or sandy bottoms.
