The Violet Sponge – Chelonaplysilla violacea is a captivating species of marine sponge with a vibrant purple hue. This sponge exhibits a unique morphology and plays a vital role in the marine environment, contributing to the diversity and ecological balance of its habitat.
Description & Characteristics
Chelonaplysilla violacea, as its name suggests, is characterized by its striking violet color, which can range from deep purple to a lighter lavender shade. Its surface is typically smooth, with a slightly bumpy texture. It grows in a variety of shapes, including encrusting, massive, and branching forms, and can reach a maximum size of up to 30 cm in diameter.
Habitat and Occurrence
The Violet Sponge – Chelonaplysilla violacea – is commonly found in the intertidal and subtidal zones of the tropical and subtropical regions of the Indo-Pacific. It is a prevalent inhabitant of coral reefs, rocky shores, and seagrass beds. It is often observed growing on a variety of substrates, including rocks, coral, and shells. This species thrives in a wide range of depths, typically residing between the surface and 30 meters below the waterline. It is an integral part of the coastal marine ecosystem, contributing to the biodiversity and ecological balance of these diverse habitats.
Taxonomy
The Violet Sponge – Chelonaplysilla violacea – is classified under the phylum Porifera, which encompasses all sponges. This remarkable species belongs to the Class: Demospongiae, which comprises the majority of sponge species, characterized by their siliceous spicules (skeletal elements). Chelonaplysilla violacea further falls under the Order: Dendroceratida, known for their branching and tree-like forms, and the Family: Darwinellidae, a diverse group of sponges found in a variety of marine environments.
Feeding
The Violet Sponge – Chelonaplysilla violacea – is a filter feeder, meaning it obtains its nourishment by filtering microscopic organisms and organic matter from the surrounding water. It accomplishes this by pumping water through its body, capturing food particles using specialized cells called choanocytes, which line its internal chambers. This feeding mechanism plays a crucial role in the marine ecosystem, contributing to the cycling of nutrients and the overall health of the habitat.
