- 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
- Radiolaria - Geology is the Way
Radiolarians are single-celled protozoa, measuring less than 0 1 – 0 2 mm in diameter, that produce intricate shells (skeletons) of amorphous silica They float as part of the zooplankton in the first 200 meters of water in the Earth’s oceans (photic zone)
- Radiolarians: What They Are Why They Matter - Biology Insights
Radiolarians are ancient, single-celled marine organisms known for their intricate, glassy skeletons These microscopic wonders have existed for hundreds of millions of years, leaving behind a remarkable fossil record
- 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
- 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
- Radiolaria - New World Encyclopedia
The main class of radiolarians are the Polycystinea They include the vast majority of the fossil radiolaria, as their skeletons are abundant in marine sediments, making them one of the most common groups of microfossils
