Haplosclerida is an order of demosponges. It contains the following families: [1]
Soest is a municipality and a town in the central Netherlands, in the province of Utrecht. It is about 6 km (4 mi) west of Amersfoort.
Demosponges are the most diverse class in the phylum Porifera. They include 76.2% of all species of sponges with nearly 8,800 species worldwide. They are sponges with a soft body that covers a hard, often massive skeleton made of calcium carbonate, either aragonite or calcite. They are predominantly leuconoid in structure. Their "skeletons" are made of spicules consisting of fibers of the protein spongin, the mineral silica, or both. Where spicules of silica are present, they have a different shape from those in the otherwise similar glass sponges. Some species, in particular from the Antarctic, obtain the silica for spicule building from the ingestion of siliceous diatoms.
The Clathrinida are an order of calcareous sponges found in marine environments. These sponges have an asconoid structure and lack a true dermal membrane or cortex. The spongocoel is lined with choanocytes.
Clathrina is a genus of calcareous sponge in the family Clathrinidae. Several species formerly in Clathrina were transferred to the newly erected genera Arturia, Ernstia, Borojevia, and Brattegardia in 2013. The name is derived from the Latin word "clathratus" meaning "latticed".
Pieter Cornelisz van Soest was a Dutch marine artist, especially prolific in battle-pieces.
Amphimedon queenslandica is a sponge native to the Great Barrier Reef. Its genome has been sequenced. It has been the subject of various studies on the evolution of metazoan development.
Haliclona is a genus of demosponges in the family Chalinidae.
Petrosia ficiformis, commonly known as the stony sponge, is a species of petrosiid sea sponge in the order Haplosclerida.
Agelas is a genus of sea sponge in the class Demospongiae.
Callyspongia is a genus of demosponges in the family Callyspongiidae.
Tiffany Lynn van Soest is an American Muay Thai kickboxer who competes in the bantamweight division. She is the current Glory Super Bantamweight Championship. In 2019, Combat Press voted her the Female Fighter of the Year.
Xestospongia is a genus of sponges in the family Petrosiidae. It contains the following species:
Niphatidae is a family of demosponges in the order Haplosclerida. It contains the following genera:
Neopetrosia proxima is a species of marine petrosiid sponge native to the tropical and subtropical waters of the western Atlantic Ocean.
Neopetrosia subtriangularis is a species of marine petrosiid sponges native to the waters off Florida and the Caribbean Sea. They superficially resemble staghorn corals.
Agelasida is an order of sea sponges in the class Demospongiae.
Anheteromeyenia is a genus of freshwater sponge. It has been recorded in the Nearctic, the Neotropics. This taxon was initially a subgenus of Heteromeyenia when K. Schöder circumscribed it in 1927, but W. M. de Laubenfels made it a genus in its own right in 1936.
Soest is an electoral constituency represented in the Bundestag. It elects one member via first-past-the-post voting. Under the current constituency numbering system, it is designated as constituency 146. It is located in eastern North Rhine-Westphalia, comprising the district of Soest.
