Leucila
Leucila is a genus of small marine sponges that belongs to the class Calcarea, a group characterized by spicules made of calcium carbonate. These sponges are typically found in shallow coastal waters, where they attach to rocks, shells, or other submerged surfaces. It feeds by filtering microscopic particles and organic matter from seawater, helping maintain water quality and contributing to marine nutrient cycles. Despite their simple body structure, they play an important ecological role in supporting biodiversity within coastal ecosystems.
Classification of Leucila
- Phylum :- Porifera (Pore bearing, cellular grade, asymmetrical or radially symmetrical)
- Class :- Calcarea (Calcareous spicules present)
- Order :- Heterocoe (Syconoid sponges with internal folds)
- Genus :- Leucila
Habit and habitat
- It is a small solitary and marine sponge.
Distribution
- Found in Europe and U.S.A.
General Characterstics of Leucila
- Anterior apical portion is narrow.
- Posterior basal portion is broad and attached to substratum.
- Osculum is situated at the anterior extremity and is surrounded by oscular fringe of monaxon spicules.
- Canal system is of primitive leuconoid type.
- Each radial canal is subdivided into elongated flagellated chambers, grouped around a common excurrent channel.
- Skeleton is of inarticulate type.
Identification
- Since the specimen has narrow anterior end with pores, oscular fringe and all above features hence it is Leucila.
