Identification:
Pseudoceros zebra is a distinctive flatworm recognized by its black body with prominent white longitudinal stripes, reminiscent of a zebra's coat. The wavy edges of its broad body undulate elegantly as it glides across the substrate, while a pair of small pseudotentacles at the anterior help it sense its surroundings. This species is easy to spot due to its bold patterning and confident movement.
Size:
Typically ranges from 2.5 to 5 cm in length.
Habitat:
Commonly found on coral reefs, especially around coral rubble, dead coral heads, and algae-covered rocks, where its prey is most abundant.
Depth Range:
Usually encountered between 3 and 20 meters deep.
Diet:
Feeds mainly on colonial ascidians and other small sessile invertebrates. It uses an eversible pharynx to digest prey externally.
Reproduction:
As with most flatworms, Pseudoceros zebra is simultaneously hermaphroditic. Reproduction involves penis fencing, a competitive behavior where each worm attempts to inseminate the other.
Fun Fact:
The striking zebra-like stripes may serve both as a warning coloration to potential predators and as a form of disruptive camouflage among the reef’s textures and shadows.
