Haliclona caerulea

Haliclona cearulea is a species of marine sponge in the family Chalinidae.[1] It is an encrusting tubular sponge that grows anchored on rocky surfaces of coral reefs.

Name[edit]

The name of the species relates to its blue color: Latin caeruleus: cerulean blue, like the sky, or the ocean.

Morphology[edit]

Haliclona caerulea takes the form of an encrusting mass of cylindrical to volcano-shaped projections between 2 and 15 cm, with oscula at the high end. The oscula are circular or oval, and between 1.3 and 5.0 mm in diameter.[2] The body has radial symmetry and consists, on the outside, of flattened cells known as pinacocytes. The inner part is formed by cells called choanocytes, equipped with a flagellum. These cells have a dual function: ingesting food particles, and maintaining the flow of water through the sponge's body. Between the two layers a more or less gelatinous substance called mesohyl. Sclerocyte cells are responsible for secreting a kind of skeleton for supporting the sponge's body, formed of spongin fibers.

As its name suggests, the most common color is blue, but individuals may be beige or white.

Distribution[edit]

It's geographic distribution includes the western tropical Atlantic, from Florida and the Gulf of Mexico, to the Caribbean Sea, reaching the West Indies and the Pacific coast of Mexico and Panama.[2] is also found on the islands of Hawaii and Guam, and its unintended introduction that reached these islands from biofouling on the hulls of ships.[3]

Habitat and Ecological roles[edit]

It is commonly seen growing in beds of the seagrass Thalassia, and in rocky coral rubble habitats.[4] Studies reported their symbiosis with calcareous alga Jania adhaerens.[5]

Aquaria[edit]

Haliclona cerulea can sometimes be found in the aquarium trade, often sold simply as "Haliclona sp."
