Paraplanocera sp. (unidentified)

Identification:
This unidentified Paraplanocera species is a strikingly elegant flatworm with a broad, oval body and slightly ruffled margins. Its base color is a rich cream or pale beige, adorned with fine iridescent lines that shimmer under light. The edge is marked by a thin, contrasting band that accentuates its graceful shape. Its body appears robust and muscular compared to many other flatworms, with rounded pseudotentacles formed by rolled anterior margins.

Size:
Up to 5–7 cm in length.

Habitat:
Typically found gliding across sandy patches near coral reefs, under rubble, or tucked into crevices. It is most often spotted on shallow to moderately deep slopes, especially during night dives.

Depth Range:
5–25 meters

Diet:
Carnivorous. Likely preys on small invertebrates such as crustaceans and mollusks, using its eversible pharynx to engulf and digest its meals.

Reproduction:
A simultaneous hermaphrodite, this species reproduces through reciprocal mating and lays gelatinous egg ribbons on hard surfaces. The planktonic larvae settle and metamorphose into benthic adults.

Fun Fact:
The bold, iridescent patterns of this Paraplanocera species may serve as a warning to potential predators, hinting that it might be unpalatable or toxic. Its confident, gliding motion across the reef only adds to its captivating presence.
