West Maas en Waal is a municipality in the Dutch province of Gelderland.
Tube-dwelling anemones or ceriantharians look very similar to sea anemones but belong to an entirely different class of anthozoans. They are solitary, living buried in soft sediments. Tube anemones live inside and can withdraw into tubes, which are composed of a fibrous material made from secreted mucus and threads of nematocyst-like organelles known as ptychocysts. Within the tubes of these ceriantharians, more than one polyp is present, which is an exceptional trait because species that create tube systems usually contain only one polyp per tube. Ceriantharians were formerly classified in the taxon Ceriantipatharia along with the black corals but have since been moved to their own class, Ceriantharia.
Notoplax is a genus of chitons in the family Acanthochitonidae.
Mesocetus is an extinct genus of baleen whale from the Miocene of Europe and North America.
Protororqualus is a genus of extinct rorqual from the late Pliocene of Mount Pulgnasco, Italy.
Plesiocetus is a genus of extinct balaenopterids found worldwide. It has had a chequered taxonomic history, having served as a wastebasket genus for a handful of mysticete species.
The Diphyidae are a family of siphonophores. These are colonial siphonophores with two nectophores arranged one behind the other. The front one includes a somatocyst, while the hind one does not. The somatocyst often contains an oil droplet for buoyancy control. A nectosac in each nectophore allows the organism to swim efficiently.
Cerianthidae is a family of tube-dwelling anemones in the order Spirularia of the subclass Ceriantharia.
Arachnactidae is a family of tube-dwelling anemones in the order Ceriantharia. It is the only family in the monotypic order Penicillaria and comprises around 38 species. They differ from other ceriantharians in the makeup of their cnidome, the relative sizes of the oral discs and the shape and structure of the mesenteries. These tube anemones dwell in parchment-like tubes immersed in soft sediment, and have two whorls of tentacles, the outer ones being much longer than the inner ones.
Nanophoca is an extinct genus of earless seals from the middle Miocene of Belgium.
Isodactylactis is a genus of cnidarians belonging to the family Cerianthidae.
Hensenanthula is a genus of cnidarians belonging to the family Botrucnidiferidae.
Botrucnidiata is a genus of cnidarians belonging to the family Botrucnidiferidae.
Apiactis is a genus of cnidarians belonging to the family Cerianthidae.
Gymnanthula is a genus of cnidarians belonging to the family Botrucnidiferidae.
Calpanthula is a genus of cnidarians belonging to the family Botrucnidiferidae.
Atractanthula is a genus of cnidarians belonging to the family Botrucnidiferidae.
Cerianthula is a genus of cnidarians belonging to the family Botrucnidiferidae.
Scrupocellaria is a genus of bryozoans belonging to the family Candidae.
