- Radiolaria - Wikipedia
Radiolarians are unicellular predatory protists encased in elaborate globular shells (or "capsules"), usually made of silica and pierced with holes Their name comes from the Latin for "radius" They catch prey by extending parts of their body through the holes
- Radiolarian | Marine Protists, Plankton, Microscopic | Britannica
radiolarian, any protozoan of the class Polycystinea (superclass Actinopoda), found in the upper layers of all oceans Radiolarians, which are mostly spherically symmetrical, are known for their complex and beautifully sculptured, though minute, skeletons, referred to as tests
- Radiolarians Species - Examples, Characteristics, Ecology, Microscopy
Radiolarians species, members of the subclass Radiolaria, are single-celled eukaryotes commonly found in marine environments (with some being colonial) Although some of the species are restricted to a specific region, these organisms are widely spread in major oceanic ecosystems across the world
- Radiolarians: Microscopic Marine Mysteries | AMNH
Radiolarians, single-celled marine organisms with intricate silica skeletons, have existed for at least 550 million years and are found in all the world’s oceans
- Introduction to the Radiolaria
Radiolaria can range anywhere from 30 microns to 2 mm in diameter Their skeletons tend to have arm-like extensions that resemble spikes, which are used both to increase surface area for buoyancy and to capture prey Most radiolarians are planktonic, and get around by coasting along ocean currents
- Diversity and ecology of Radiolaria in modern oceans - PMC
These have existed for millions of years and include the Radiolaria, a group of marine protists, many of which bear delicate mineral skeletons of different natures Radiolaria are well known for their paleontological signatures, but little is known about the ecology of modern assemblages
- Radiolaria. org gt; What are radiolarians
Radiolarians are part of the marine plankton They occur in all oceans, including shallow seas, bays, fjords, etc , but almost invariably at salinities above 30 parts per thousand (slightly lower than normal marine values)
- Radiolarians - Incredible Microplankton ~ MarineBio Conservation Society
Radiolarians are single-celled eukaryotic marine organisms known for their intricate mineral skeletons and important ecological and geological roles in the oceans
