Calliotropis antarctica is a species of sea snail, a marine gastropod mollusk in the family Eucyclidae. ^[1]

Shell Sculpture

• The size of the Calliotropis antarctica shell varies between 8 mm and 10.5 mm. Its thin, iridescent beauty belies the harsh environment it inhabits, the spiral rows of tubercles on its shell create a mesmerizing pattern, reminiscent of ancient glyphs etched by the icy winds.

Taxonomic Journey

• Calliotropis antarctica thrives in the cold embrace of the Southern Ocean. Its habitat extends from the rocky shores to the deeper abyssal plains, The species exhibits remarkable adaptations to survive the extreme conditions. Its thin shell minimizes buoyancy, allowing it to cling to submerged rocks. ^[2]

Feeding Habits

The snail grazes on diatoms, algae, and other microscopic organisms. Its radula—a specialized feeding organ—ensures efficient consumption, The Antarctic currents carry a bounty of planktonic life, sustaining this delicate mollusk. ^[3]

The Ross Sea Connection

• Dr. R. K. Dell’s research on Antarctic mollusks emphasized the fauna of the Ross Sea1, The Ross Sea, a pristine marine ecosystem, shelters countless species, including our unassuming snail. ^[4]

Conservation Status

• While not officially assessed, Calliotropis antarctica faces threats from climate change, ocean acidification, and invasive species, Scientists monitor its population dynamics, hoping to unravel its role in the fragile Antarctic food web. ^[5]
