Scientific Name: Caloria indica
Common Name: Indica aeolid, Indian Caloria

Size: Up to 3 cm
Depth Range: 1 – 30 m
Habitat: Coral reefs, rocky substrates, and algal-covered areas, often in shallow lagoons and reef flats
Diet: Feeds primarily on hydroids, from which it may sequester nematocysts for its own defense
Reproduction: Hermaphroditic; individuals exchange sperm and lay coiled, ribbon-like egg masses on hard surfaces
Fun Fact: Caloria indica is known for its brilliant colors—bright orange or reddish cerata with iridescent blue or white tips—which serve as a warning to potential predators. These vibrant hues also make it a favorite among underwater macro photographers.

Observation Tip: Look for this striking nudibranch crawling delicately among hydroids or algae, especially on night dives or during calm daylight conditions. Its elongated body and vivid colors make it stand out, despite its small size.
