Radiolaria Polycistina Acantharea 3D-modell

Name of the specimen: Acantharea model Triangles: 1175552 Vertices: 586296 Information: The Radiolaria, also called Radiozoa, are protozoa of diameter 0.1–0.2 mm that produce intricate mineral skeletons, typically with a central capsule dividing the cell into the inner and outer portions of endoplasm and ectoplasm. The elaborate mineral skeleton is usually made of silica. They are found as zooplankton throughout the ocean, and their skeletal remains make up a large part of the cover of the ocean floor as siliceous ooze. Due to their rapid change as species, they represent an important diagnostic fossil found from the Cambrian onwards. Age: Cambrian to Recent Habitat: Marine
