Dwarf Planaxis

Hinea lineata

Dwarf Planaxis, a small marine snail, reaches a maximum shell length of 10 mm. Its shell is characterized by an ovate, conical shape that is smooth and diaphanous, adorned with numerous narrow, transverse lines of blackish brown against a white background. The spire consists of six slightly convex whorls, with the body whorl being larger and more inflated than the others. The aperture is subrounded, showcasing a violet color and external colored lines, while the outer lip is thin and sharp, marked with brown lines. These features help distinguish it from similar species in its habitat. This species is found in various locations across the Atlantic Ocean, including Angola, Cape Verdes, West Africa, and St. Helena, as well as in the Gulf of Mexico and the Caribbean Sea. Dwarf Planaxis typically inhabits offshore and intertidal coral reefs, bays, and coastal lagoons, often residing on algae, gravel, rock, and sand. It has been recorded at depths ranging from 0 to 48 meters, with most occurrences being shallower than 40 meters. Dwarf Planaxis is herbivorous, feeding primarily on algae. The species is gonochoric and reproduces by broadcasting its eggs into the water, where embryos develop into planktonic larvae before maturing into adults. Encountering this snail while diving can be a subtle experience, as their small size makes them easy to overlook among the reef's diverse life. The conservation status of Dwarf Planaxis has not been evaluated.
