Elongated Violet Snail

Janthina umbilicata

Elongated Violet Snail is a small, holoplanktonic sea snail that can reach a maximum shell length of 9.5 mm. This species is characterized by its elongated shape and violet coloration, which helps distinguish it from other marine gastropods. Its small size makes it less noticeable, but divers may spot it floating in the water column or washed up on beaches. The snails are adapted to a pelagic lifestyle, often found in open water rather than on the sea floor. This species inhabits tropical regions, specifically between latitudes 26°N and 16°S and longitudes 69°E to 0°E, including the Atlantic Ocean and Indo-Pacific. The Elongated Violet Snail is typically found at depths ranging from 0 to 0 meters, indicating its preference for surface waters. It is commonly associated with marine environments where it can drift with currents. Elongated Violet Snails primarily feed on plankton, which they capture while floating in the water column. They reproduce through a process known as broadcast spawning, where eggs are released into the water, allowing embryos to develop into planktonic larvae before maturing into adults. Encounters with this species during dives may be rare, as they are often found in open water rather than near the reef. The conservation status of Elongated Violet Snail has not been evaluated by the IUCN, leaving its population status uncertain.
