Verongia fistularis (Pallas, 1766) Aplysina fistularis (A. fistularis), also known as the yellow tube sponge or yellow sponge , [1] is a species of sea sponge in the order Verongiida. [2] Aplysina fistularis is a golden or orange-brown color with a conulose surface. The animal is abundant in the Caribbean, where it is commonly found in reefs of ...
Aplysina aerophoba. Aplysina aerophoba is sometimes heavily infested with Nausithoe polyps. In more tropical areas like the Canary Islands Aplysina aerophoba tends to take on a smoother appearance. Aplysina aerophoba is a species of sponge in the family Aplysinidae. It is a yellow, tube-forming or encrusting sponge and is native to the eastern ...
Aplysina insularis is a large sponge and consists of one or more cylindrical tubes united at the base. Each one narrows at the apex into a large osculum and this may be surrounded by small, finger-like projections. Slender tendrils and larger rope-like projections may also occur, and in areas with high levels of sedimentation, these may exceed ...
Aplysina archeri, also known as a stove-pipe sponge because of its shape, is a species of tube sponge that has long tube-like structures of cylindrical shape. Although they can grow in a single tube, they often grow in large groups of up to 22 tubes. [ 2] A single tube can grow up to 5 feet (1.5 m) high and 3 inches (7.6 cm) thick.
About 311 million years ago, in the Late Carboniferous, the order Spongillida split from the marine sponges, and is the only sponges to live in freshwater environments. [7] Some species are brightly colored, with great variety in body shape; the largest species are over 1 m (3.3 ft) across. [ 5 ]
Included are the yellow tube sponge, Aplysina fistularis, the purple vase sponge, Niphates digitalis, the red encrusting sponge, Spirastrella coccinea, and the gray rope sponge, Callyspongia sp. Sponges are similar to other animals in that they are multicellular, heterotrophic, lack cell walls and produce sperm cells.
Cliona celata, occasionally called the boring sponge, is a species of demosponge belonging the family Clionaidae. [1] It is found worldwide. This sponge bores round holes up to 5 millimetres (0.20 in) in diameter in limestone or the shells of molluscs, especially oysters. The sponge itself is often visible as a rather featureless yellow or ...
The calcareoussponges[ 2 ][ 3 ] (class Calcarea) are members of the animal phylum Porifera, the cellular sponges. They are characterized by spicules made of calcium carbonate, in the form of high- magnesium calcite or aragonite. While the spicules in most species are triradiate (with three points in a single plane), some species may possess two ...
