Sponges in the sea near the Caribbean isle Saba in the Netherlands Antilles
Sponges in the sea near the Caribbean isle Saba in the Netherlands Antilles. The sponges or poriferans are animals of the phylum Porifera. Their bodies consist of jelly-like mesohyl sandwiched between two thin layers of cells. While all animals have unspecialized cells that can transform into specialized cells, sponges are unique in having some specialized cells that can transform into other types, often migrating between the main cell layers and the mesohyl in the process. Sponges do not have nervous, digestive or circulatory systems. Instead most rely on maintaining a constant water flow through their bodies to obtain food and oxygen and to remove wastes, and the shapes of their bodies are adapted to maximize the efficiency of the water flow. All are sessile aquatic animals and, although there are freshwater species, the great majority are marine (salt water) species, ranging from tidal zones to depths exceeding 8,800 metres ( mi). Saba is the smallest island of the Netherlands Antilles. It consists largely of the sleeping volcano, Mount Scenery (877 m or 2855 feet), the highest point of the Netherlands and has a total land area of 5 sq miles or 13 km2. The major settlements on Saba include The Bottom, Windwardside, Hell's Gate and St. Johns.
