Brittle star - Wikipedia Brittle stars, serpent stars, or ophiuroids (from Latin ophiurus 'brittle star'; from Ancient Greek ὄφις (óphis) 'serpent', and οὐρά (ourá) 'tail'; referring to the serpent-like arms of the brittle star) are echinoderms in the class Ophiuroidea, closely related to starfish.They crawl across the sea floor using their flexible arms for locomotion. Wildlife Fact Sheets: Brittle Star - Ocean Conservancy Although brittle stars and starfish are closely related, they are completely different species. Each brittle star has a distinct central disk and five skinny, flexible arms. The central disk is made up of a skeleton of calcium carbonate and contains all the internal organs. Brittle stars' arms twist and coil to help them move across the seafloor.

Body Systems - Brittle Stars Cross-section of a brittle star arm Brittle Stars pocesses a skeleton made of calcium-cabonate in the form of calcite. These calcite ossicles are fused together to form armor plates. These plates are covered with epidermis (skin) to create a smooth, strong covering.

Brittle Star: Fascinating Sea Life - ThoughtCo The largest known brittle star is Ophiopsammus maculata, with a disk measuring 2-3 inches across, and arm length between 6-7 inches. They weigh between 0.01-0.2 ounces and come in a wide variety of colors. Some are even capable of bio-luminescence, generating their own light.

Sea Star Anatomy 101 - ThoughtCo Sea stars are echinoderms, which means they are related to sea urchins, sand dollars, basket stars, brittle stars, and sea cucumbers. All echinoderms have a calcareous skeleton covered with skin. They also usually have spines. Here you will learn about the basic aspects of sea star anatomy. Phylum Echinodermata | Biology for Majors II - Lumen Learning Brittle stars belong to the class Ophiuroidea. Unlike sea stars, which have plump arms, brittle stars have long, thin arms that are sharply demarcated from the central disk. Brittle stars move by lashing out their arms or wrapping them around objects and pulling themselves forward.

Larval specimens of the common starfish Asterias rubens (phylum Echinodermata) occur in the plankton among those of sea urchins, sea cucumbers, and brittle stars. A majority of the starfish species disperse exceedingly large numbers of their gametes (eggs and sperm) freely into the water in the hope of an external fertilization event.

The Difference Between Sea Stars and Brittle Stars Brittle stars, on the other hand, have much thinner arms that appear more "whip-like" than those of sea stars. The arms connect to a central disk, and it's relatively easy to tell where the arm ends and the disk begins. Next, look at how they move. Sea stars rely on their water vascular system to move.

Ophiuroidea (Brittle and Basket Stars) | Encyclopedia.com A large brittle star with a disk as much as 0.9 in (23 mm) in diameter. The arms are long, about 13.7 in (350 mm) and broken near the tip. A soft, smooth skin covers both the disk and the arms. The spines are shorter than the arm width; the distal spines are flattened, turning into compound hooks with 2-4 lateral teeth.
