Notes on Violet Sea Snails in Ayeyarwady Intertidal Waters, Myanmar
Keywords:
Ayeyarwady Intertidal Waters, genus Janthina, Myanmar, notes, violet sea snailsAbstract
A total of 5 species of violet sea snails Janthina exigua, J. globosa, J. janthina, J. pallida, and J. umbilicata were collected from the intertidal shoal of Ayeyarwady coastal waters from January to December 2024. The shell appearance, habitat, buoyancy, feeding system, and local ecological adaptation (bubble raft for buoyancy, dietary specialization, reduced and modified shell and foot, reproduction, pelagic lifestyle) of the genus Janthina were studied. Some ecological aspects of the distribution, occurrence, composition, and abundance of violet sea snails in different sampling sites of the Ayeyarwady intertidal waters were also studied with species and station-wise correlation.
