OPHIUROIDS Meaning and
Definition
-
Ophiuroids, also known as brittle stars, are a class of echinoderms characterized by their long, slender arms that radiate from a central disk-shaped body. They belong to the phylum Echinodermata, which includes other marine organisms such as sea stars, sea urchins, and sea cucumbers. Ophiuroids can be found in various marine habitats, ranging from shallow coastal waters to the deep ocean.
The arms of ophiuroids are highly flexible and can exhibit remarkable movements, allowing them to crawl, walk, and even swim through water. They are covered with small calcite plates called ossicles, which provide support and protection to the fragile internal organs. The body structure of ophiuroids is more delicate compared to sea stars, as they lack the distinctive tube feet present in other echinoderms.
Ophiuroids are considered benthic, meaning they primarily inhabit the seafloor, where they scavenge for organic matter and small organisms. They have a well-developed water vascular system that helps in feeding, respiration, and locomotion. While some species are filter feeders, others are predators, using their long arms to catch prey like small crustaceans and plankton.
Ophiuroids exhibit both sexual and asexual reproduction. Sexual reproduction involves the release of sperm and eggs into the water, where fertilization occurs externally. The larvae undergo a period of development in the plankton before settling to the seafloor and growing into adult ophiuroids.
These fascinating creatures play a vital role in marine ecosystems as they serve as prey for other organisms and contribute to nutrient cycling. Ophiuroids have existed on Earth for millions of years and have adapted to a wide range of environmental conditions, making

Etymology of OPHIUROIDS
The word "Ophiuroids" has its etymology rooted in Greek. It is derived from the Greek words "ophis" meaning "snake" and "oura" meaning "tail". Combining these two elements, "ophis" and "oura", results in "Ophiuroids", which refers to a class of echinoderms commonly known as brittle stars or serpent stars. These marine animals have long, slender arms that resemble snake-like tails, hence the derivation of the term from Greek.
