Ophiurida - English Definition & Meaning

Definition

Ophiurida is an order within the class Ophiuroidea, encompassing most of the brittle star species. Essentially, it's a more specific grouping within the broader category of brittle stars. These creatures are characterized by their distinct central disc and long, flexible arms used for locomotion. Many familiar types of brittle stars fall into this classification. Think of Ophiurida as a popular sub-group within the brittle star family. They thrive in various marine habitats, contributing to the biodiversity of seafloor ecosystems.

Etymology

The name "Ophiurida" is derived from the same Greek roots as "Ophiuroidea." "Ophis" means serpent, and "oura" means tail. The suffix "-ida" is a taxonomic suffix used to denote an order within biological classification. Therefore, Ophiurida literally means "snake-tailed order." It signifies a group of animals that share the characteristic snake-like arms within the larger class of brittle stars. This naming convention helps organize and classify these marine invertebrates.
