According to Wikipedia Radiolaria 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.
What techniques did Ernst Haeckel use?
Rendered with graphic precision and delicate shading, Haeckel’s work embraced the Darwin theory of evolution and helped to educate the world about microscopic organisms that were previously unseen.
What is Ernst Haeckel’s art style?

Haeckel’s images quickly spread across the globe and would influence many artists and architects of the era, so much so that they became an inspiration for Art Nouveau.
Why was Ernst Haeckel artwork important?
Haeckel made hundreds of such renderings during his lifetime, works which were used to explain his biological discoveries to a wide audience. In addition to these visual masterpieces, Haeckel also discovered many microbes, and coined several scientific terms commonly known today, such as ecology, phylum, and stem cell.

How do Radiolaria eat?
When feeding as predators, Radiolaria may capture diatoms, tintinnids, and other calcareous organisms by ingesting them into their central cavity. They trap their prey on the peripheral network of rhizopodia.
Where are radiolarians found?
open-ocean
Radiolarians are silica-secreting, single-celled protists that dwell in open-ocean locations. They occur throughout the water column from near surface to great depths.
Why are the Ernst Haeckel so famous?

Ernst Haeckel was a German biologist, naturalist, and artist who pioneered the practice of using artistic illustrations to capture the likenesses of animals in the wild during the 19th century.

Are Radiolaria extinct?
Ninety percent of radiolarian species are extinct.
How many types of radiolarians are there?
There are more than 15,000 living and fossil species of radiolaria, of which 800 to 1,000 species live in the world’s oceans. Radiolarians have captivated scientists since these single-celled organisms were first observed under the microscope in the 19th century.
What are radiolarians used for?
Radiolarians are also an important food source for a number of organisms in their environment. They provide nutrition for such organisms as salps. As such, they are part of the food chain in their respective habitats.
What did Ernst Haeckel’s drawings show?
vertebrate embryos
Ernst Haeckel (1834–1919)
Haeckel’s illustrations show vertebrate embryos at different stages of development, which exhibit embryonic resemblance as support for evolution, recapitulation as evidence of the Biogenetic Law, and phenotypic divergence as evidence of von Baer’s laws.
What is discovered by Ernst Haeckel?
biogenetic law, also called Recapitulation Theory, postulation, by Ernst Haeckel in 1866, that ontogeny recapitulates phylogeny—i.e., the development of the animal embryo and young traces the evolutionary development of the species.

What are the examples of radiolarians?
For the most part, Radiolarians are free-living organisms that feed on a variety of food sources in their environment.
…
Some of the species that fall under the subclass Radiolaria include:
- Acanthosphaera actinota.
- Acrobotrys cribosa.
- Acrosphaera cyrtodon.
- Acrosphaera australis.
- Acanthodesmia vinculata.
- Acrosphaera spinosa.
How are radiolarians classified?
Extant radiolaria are classified using features of both the preservable skeleton and the soft parts, which makes the classificaiton of fossil forms extremely difficult.
Are Haeckel’s drawings still used?
Ironically, although Haeckel’s drawings are used only as relics now, modern molecular genetic studies show that his fundamental point – that there are important similarities between different vertebrate embryos – seems less mistaken, even though his diagrams are profoundly wrong.
