Scientific Name: Tubulophilinopsis pilsbryi
Common Name: Pilsbry’s tubulophilinopsis

Adult Size: 20 – 50 mm
Depth Range: 5 – 30 m
Biotope / Habitat: Sandy bottoms and rubble areas near coral reefs, gliding slowly across sand and algae patches
Diet: Carnivorous; preys on small invertebrates, using its powerful jaws and radula to capture and consume them
Reproduction: Hermaphroditic; reciprocal mating occurs, with small, coiled egg ribbons laid in sandy or rubble areas
Fun Fact: Tubulophilinopsis pilsbryi’s sleek, light white body with fine black markings makes it a stealthy predator of the reef’s sandy edges, blending beautifully with the environment.

This subtly striking slug is a quiet hunter, its light and dark coloration and streamlined shape making it a true master of camouflage in sandy reef zones.
