The Leech – Branchellion torpedinis is a species of parasitic leech belonging to the family Piscicolidae. This fascinating creature is characterized by its unique morphology and adaptations for a parasitic lifestyle.
Description & Characteristics
Branchellion torpedinis possesses a distinct appearance, with a flattened body and a prominent sucker at each end. These suckers are essential for attachment and feeding on its host. The leech’s body is typically brown or grayish in color, with a slightly segmented appearance. They can reach a maximum size of approximately 10 centimeters in length, making them relatively large compared to other leech species.
Habitat and Occurrence
Branchellion torpedinis primarily inhabits the marine environment, with a preference for coastal waters. They are commonly found in association with their host, the electric ray (Torpedo spp.), and are often observed attached to the gills or body surface of these fish. Their distribution encompasses the Mediterranean Sea, the Black Sea, and parts of the Atlantic Ocean. This geographic range aligns with the distribution of their preferred host, the electric ray.
Taxonomy
Branchellion torpedinis is classified within the family Piscicolidae, a group of leeches that are primarily parasitic on fish. Piscicolidae belongs to the Order Rhynchobdellida, which encompasses leeches with a protrusible proboscis used for feeding. This order, in turn, falls under the Class Clitellata, a diverse group of segmented worms that includes earthworms and leeches.
Feeding
Branchellion torpedinis is a parasitic leech, meaning it derives its sustenance from the blood of its host. It attaches to the electric ray using its strong suckers and uses its proboscis to pierce the host’s skin and access its bloodstream. This parasitic relationship allows Branchellion torpedinis to thrive in the marine environment.
