Scientific Name: Odontoglaja mosaica
Common Name: Mosaic odontoglaja

Adult Size: 10 – 20 mm
Depth Range: 5 – 20 m
Biotope / Habitat: Coral reef slopes and sandy areas near reefs, gliding over algae and rubble-covered substrates
Diet: Feeds on small invertebrates and possibly tiny mollusks, using its radula to scrape and consume prey
Reproduction: Hermaphroditic; mates reciprocally, with tiny, coiled egg ribbons laid on reef rubble or algae
Fun Fact: Odontoglaja mosaica’s translucent white body is beautifully decorated with a fine, reticulated pattern of dark lines, giving it a stunning “mosaic” appearance in reef shallows.

This small but striking slug is a master of subtle elegance, its delicate patterns blending perfectly with the reef’s algae and sandy patches. It’s a delightful find for macro photographers and marine enthusiasts!
