Description & Characteristics

Leptoplana tremellaris is characterized by its flattened, ribbon-like body, typically measuring up to 10 cm in length. It exhibits a distinct coloration, often displaying a mottled brown or grayish-brown pattern. The dorsal surface of the worm is covered in numerous small papillae, while the ventral side features a prominent mouth located at the anterior end.

Habitat and Occurrence

Leptoplana tremellaris is a marine species that primarily inhabits intertidal zones and shallow coastal waters. It is commonly found attached to rocks, algae, and other submerged surfaces. This flatworm’s distribution encompasses a range of marine zones, including the infralittoral and circalittoral zones. This species thrives in environments with moderate salinity and temperatures, often displaying a preference for areas with ample food sources.

Taxonomy

Leptoplana tremellaris belongs to the order Polycladida, which encompasses a diverse array of flatworms characterized by their branched digestive systems. This species is further classified within the family Leptoplanidae, a group of flatworms known for their simple, elongated bodies and the presence of a single opening that serves as both mouth and anus.

Feeding

Leptoplana tremellaris is a carnivorous predator, feeding primarily on smaller invertebrates like polychaetes, crustaceans, and other flatworms. It captures its prey using a muscular pharynx, a specialized feeding structure that can extend from the mouth to engulf and ingest food. The digestive system of Leptoplana tremellaris, though simple, is highly efficient, allowing the flatworm to extract nutrients from a variety of prey items.
