Identification:
Paraplanocera sp.02 A is a large and flamboyant flatworm with a broad, oval body shape. It is characterized by an intense light base color, often white or light brown, adorned with iridescent lines across the dorsum. The margin is subtly undulating and usually edged with a thin contrasting band that may shimmer under light. The body is thick and muscular compared to many other flatworm species, with short, rounded pseudotentacles formed by rolled anterior margins.

Size:
Up to 6 cm in length.

Habitat:
Typically found crawling over sandy patches near coral reefs, under rocks, or hidden in crevices. It can also be spotted on coral rubble or occasionally on reef slopes during night dives.

Depth Range:
5 – 30 meters

Diet:
Carnivorous. Likely feeds on small invertebrates, such as crustaceans or mollusks, using its eversible pharynx to capture and digest prey.

Reproduction:
Simultaneous hermaphrodite. Like other polyclad flatworms, it engages in reciprocal mating and lays gelatinous egg masses on hard substrates. Larvae are free-swimming before settling and metamorphosing into benthic adults.

Fun Fact:
The bold coloration and iridescence of Paraplanocera sp. may serve as a warning signal (aposematism), deterring potential predators by suggesting it could be toxic or distasteful. Its confident, gliding movements only enhance this impression.
