description Cidaris rugosa Overview
Cidaris rugosa is a species of cidaroid sea urchin, a marine echinoderm whose body is enclosed by a rigid, calcitic test and protected by movable spines. H. L. Clark described the species in 1907.
It is of interest in zoology and skeletal-material research because echinoid tests are built from a porous calcite framework, and studies of cidaroids use that structure to examine how form and mineral organization work together.
help Cidaris rugosa FAQ
What kind of animal is Cidaris rugosa?
Cidaris rugosa is a species of cidaroid sea urchin, a marine echinoderm. Its body is enclosed by a rigid calcitic test and protected by movable spines.
Who described Cidaris rugosa?
H. L. Clark described the species in 1907. That taxonomic history places its formal scientific description in the early twentieth century.
What is a sea urchin test?
The test is the rigid skeletal shell that encloses a sea urchin's body. In Cidaris rugosa, the test is made of calcite and is accompanied by movable protective spines.
Why is Cidaris rugosa useful in zoological research?
Its echinoid test provides hard skeletal material for studying sea-urchin form and classification. Cidaroid spines and test structure are also relevant to research on echinoderm skeletal materials.
