Identification:
Pseudoceros sp.32 D is a striking and visually distinctive flatworm belonging to the Pseudoceros genus. This unidentified species features a dark brown to black background adorned with fine yellow lines and sometimes faint color streaks along the margins. Like many Pseudoceros, it glides smoothly over the reef with its broad, undulating body and rudimentary pseudotentacles at the front.

Size:
Approximately 2.5 – 4 cm in length.

Habitat:
Often observed on reef flats, coral rubble, or algal-covered rocks, especially in shallow tropical waters.

Depth Range:
Usually found between 3 – 15 meters depth.

Diet:
Feeds on colonial ascidians and other small sessile invertebrates by everting a pharynx to digest prey externally.

Reproduction:
Hermaphroditic, with partners engaging in the fascinating behavior known as penis fencing to determine sexual roles. Fertilized individuals lay gelatinous egg ribbons on solid substrates.

Fun Fact:
Despite being undescribed, Pseudoceros sp.32 D is instantly eye-catching thanks to its leaf-like pattern of yellow lines—a perfect camouflage against sandy or encrusted reef surfaces.
