The persian carpet flatworm typically measures between 3.1 and 3.9 inches in length.

The persian carpet flatworm is primarily found in the tropical and subtropical waters of the Indo-Pacific region.

The persian carpet flatworm is mainly found in the shallow waters of coral reefs and rocky areas, typically between 16 and 98 feet deep.

The patterns of the persian carpet flatworm serve as a defense mechanism to signal its toxicity to potential predators and deter them from attacking.

The flatworms of this species often hide in crevices and rocky recesses during the day, emerging at night to feed.

The persian carpet flatworm is hermaphroditic, possessing both male and female reproductive organs. During mating, two individuals engage in a fight where each attempts to inject sperm into the other while avoiding being fertilized.

This behavior, observed in several species of flatworms, is a form of sexual competition aimed at maximizing the reproductive success of individuals.

Like many planarians, the persian carpet flatworm has a remarkable ability to regenerate. If a part of its body is separated, the animal can regenerate the missing part, which is a characteristic trait of flatworms in general.
