The geographical distribution of Septaria porcellana includes India, the Philippines, Indonesia, New Guinea and New Caledonia, found in still and swift currents on stones anywhere from a few meters from he sea to 5-6 kilometers inland.[3]
The length of the shell attains 13.1mm. The shell is symmetrical, cap-like and relatively deep and wide. The outside base color is yellow-brown with a black or purple-pink pattern of triangles and horizontal lines. Inside is white to light gray, septum narrow, and its edge curved and tinged yellow.[3]
Sexual dimorphism in the species presents as males being generally smaller than females. Male reproductive organs consist of a large flap-like penis with a papilla and a small auxiliary gland. Females have a ventral remnant of a spermatophore sac without spermatophores.[3]
