Bulla_striata

Medium sized mollusc with a hard opaque external shell. Shell is brown mottled with white and thick, but the aperture (opening) is elongated and wide; spire involute. Cephalic shield is mottled a light brown with two paler areas around eyes. A pair of inrolled cephalic tentacles is present and a pair of posterior flaps covers the anterior part of the shell. Parapodia are small and only partially cover the shell. The posterior lobe is reduced and partially visible. Size range of specimens 3-17mm, the smaller specimen was found on algae, but this species is found in fine silt to muddy sand.

Specific characteristics: The size and shape of the shell in this species are sufficient to separate from related taxa.
