)The demosponges originated in the Cambrian period and form the largest class of the phylum Porifera, containing about 85% of all described Holocene species. Their coloring is not very intense; most sponges in this order come in delicate shades of purple, lavender, light brown or blue.

Species of the order Verongida are easily noticed tube-, fan-, or vase-shaped sponges, frequently colored a deep sulphur yellow. The class Demospongiae is divided into three subclasses:1. There are species that are capable of hollowing out limestone, penetrating deep inside rocks, coral heads, and shells. The reason for that - we have demos, please review a demo product carefully before buying. The Sclerospongiae are hard, stony sponges with a rigid calcareous basal skeleton in addition to an otherwise "normal" demosponge type of skeleton and spicule complement. Carnivorous sponge (Asbestopluma hypogea); 7. Since 1985 the class name Sclerospongiae has been discarded and its familiesreassigned to different orders on the basis of characteristics reflecting common ancestry.Another polyphyletic group is the former order Lithistida, which included many fossil and several Holocene species characterized by a special type of spicules called desmas. Occasionally reproduces by means of asexual buds.German: Meerschwamm; Greek: Fino, Matapas; Italian: Spugna da bagno.Globular-massive sponges, usually over 4 in (10 cm) in diameter, varying in color from white to black depending on environmental circumstances, with a finely conulose (cone-shaped) surface and spongy-elastic consistency.On rocks and in caves from the shoreline to the edge of the Little is known besides feeding ecology and reproductive biology.Viviparous; separate sexes. Asexual reproduction occurs by means of budding, fragmentation, or the production of resistant globular bodies called gemmulae. When these sponges are damaged or exposed to air, their color changes rapidly to a deep purple or black.The Astrophorida, Chondrosida, Hadromerida, Halichondrida, both the marine and freshwater Haplosclerida, the Homoscleromorpha, Poecilosclerida and most Spirophorida have a worldwide distribution. Because they are so delicate that… whale, aquatic mammal of the order Cetacea, found in all oceans of the world. In general, sponges in this subclass have skeletons made of spon-gin and spicules in different proportions, with a variety of skeletal structures. As of 2002, however, with the publication of Systema Porifera, several changes in classification have been made and definitions refined. Asexual reproduction occurs occasionally by means of gemmules attached to the base of the stalk.An elegant, attractive sponge; as such, a pleasure for snorklers and divers to collect.English: Great vase sponge, volcano sponge; German: Grosser Vasenschwamm.A large erect reddish brown, barrel- or cup-shaped, thick-walled sponge as much as 4.92 ft (1.5 m) high, with prominent ridges or knobs at the surface. They are frequently cushion-shaped; however, encrusting, branching, tubular, vase-, and fan-shaped forms are also quite common. The axial filament is embedded in a triangular or hexagonal cavity. They include 76.2% of all species of sponges with nearly 8,800 species worldwide (World Porifera Database). The new species is a
