Lineated Cominella

Cominella lineolata

Cominella lineolata is a predatory sea snail characterized by its spindle-shaped smooth shell, which can range in length from 20 mm to 39 mm. The shell features an elongated and pointed spire, a short siphonal canal, and a large oval aperture. Its outer lip is adorned with deep violet lines intersected by white lines, while the ground color is a greenish brown with black bands. The columella is smooth and bright yellow, and the operculum is small and pointed, with a reddish brown hue. This species inhabits marine environments off the coasts of New Zealand and Australia, including New South Wales, South Australia, Tasmania, Victoria, and Western Australia. It is typically found in shallower waters, with recorded depths all under 40 meters, and most occurrences at depths of about 10 meters or less. As a benthic organism, it prefers habitats such as rocky reefs and sandy bottoms. Cominella lineolata is a non-broadcast spawner, meaning it does not release its eggs into the water column. Instead, it has a direct development life cycle that excludes a trocophore stage. Encounters with this species during dives can be intriguing, as divers may observe its unique shell patterns and feeding behavior, which involves preying on small invertebrates. The conservation status of this species is not evaluated, indicating a lack of current data on its population trends.
