OPHIUROID Meaning and
Definition
-
An ophiuroid is a marine invertebrate belonging to the class Ophiuroidea within the phylum Echinodermata. Ophiuroids, commonly known as brittle stars or serpent stars, are characterized by their sleek and elongated body structure, which resembles a small serpent. They are distinct from true starfish (asteroids) due to their flexible arms that can be gracefully moved and bent, rather than being rigid and immovable.
Ophiuroids typically have five slender and fragile arms, although some species may have more. These arms possess a remarkable ability to regenerate if discarded or damaged, contributing to their remarkable resilience. They exhibit a wide range of colors, including shades of red, brown, yellow, and orange, aiding in their camouflage within their benthic habitats.
Found in oceans across the globe, ophiuroids primarily dwell in shallow to deep waters, from rocky shores to abyssal depths. They are scavengers or filter feeders, using their arms to capture particles from the surrounding water column or sift through sediment in search of organic matter. Ophiuroids can also use their arms for locomotion, as they utilize hundreds of tiny tube feet equipped with adhesive organs allowing them to swiftly crawl on various substrates.
Ophiuroids play an essential role in marine ecosystems as they assist in nutrient recycling and serve as prey for larger marine organisms. Their intricate arm movements and graceful locomotion make them a fascinating subject for scientific study, contributing to our understanding of marine biodiversity and evolutionary adaptations within the animal kingdom.
