TETRABRACHIUS Meaning and
Definition
-
Tetrabrachius is derived from the Greek root word "tetra," meaning four, and "brachius," meaning arm or branch. Literally translated, tetrabrachius refers to an organism or being with four arms or branches. However, within the realm of zoology and biology, the term holds a more specific meaning.
Tetrabrachius is a taxonomic term that refers to a particular class within the phylum Echinodermata, which includes a diverse group of marine animals such as starfish, sea urchins, and sand dollars. Specifically, it describes the members of the class Asteroidea, commonly known as starfish or sea stars, due to their distinct arm-like structures.
Starfish are identified by their radial symmetry, with their body divided into multiple arms extending from a central disk. These arms, or branches, are typically arranged in a pentagonal or star-shaped pattern and can vary in number from species to species. While most starfish have five arms, those belonging to the class Tetrabrachius are characterized by having four arms.
The term tetrabrachius is primarily used by scientists and researchers to classify and describe these particular starfish species. It allows for clear differentiation from other members of the Asteroidea class, assisting in the organization and understanding of their evolutionary history, anatomy, behavior, and ecological relationships.

Etymology of TETRABRACHIUS
The word "tetrabrachius" is derived from two roots: "tetra" and "brachius".
The prefix "tetra-" comes from the Greek word "tétra", meaning "four". It is commonly used to refer to the number four or something consisting of four parts.
The root "brachius" is derived from the Greek word "brakhýs", which means "short" or "brief". It is often used in biology to describe various species with short limbs or appendages.
When combined, "tetra-" and "brachius" in "tetrabrachius" form a word that suggests something with four short limbs or appendages.
