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 ...
Brittle star | Deep-Sea, Segmented Arms, Radial Symmetry
Brittle star, any of the 2,100 living species of marine invertebrates constituting the subclass Ophiuroidea (phylum Echinodermata). Their long, thin arms—usually five and often forked and spiny—are distinctly set off from the small disk-shaped body.
Brittle star genome provides information on the evolution of ...

Brittle Star: Fascinating Sea Life - ThoughtCo
2019年6月15日 · Brittle stars (Ophiurida) are echinoderms, the same family that includes sea stars (commonly called starfish), sea urchins, sand dollars, and sea cucumbers. Compared to sea stars, brittle stars' arms and central disk are much more distinctly separated, and their arms allow them to move gracefully and purposefully in a rowing movement.

2024年7月19日 · Brittle stars are a species-rich class of echinoderms with outstanding regenerative abilities, but investigations into the genetic bases of regeneration in this group have been hindered by the...
Diving Into the Brittle Star Genome to Understand the Evolution …
2024年11月22日 · They’re after brittle stars—marine animals with long, slender, serpent-like arms—to peek into the genes that give them distinct characteristics, including the power of regeneration. Brittle stars belong to the phylum Echinodermata, which includes sea stars, sea urchins, sea cucumbers, and sea lilies.
Brittle Stars - University of Washington
Brittle stars belong to Class Ophiuroidea (Phylum Echinodermata) and have radial symmetry, with five elongate, skinny arms extending from their central disc, or body. The lava rocks at Axial Seamount are typically covered with many members of …
Global Diversity of Brittle Stars (Echinodermata: Ophiuroidea)
The Ophiuroidea or brittle stars, basket stars (euryalids with branching arms) and snake stars (euryalids with non-branching arms), are the largest group among extant echinoderms, with 2064 described species [1], found in all oceans from the intertidal to the greatest depths.
Brittle star - Encyclopedia.com
Brittle stars are starfish-like echinoderms (phylum Echinodermata, class Ophiuroidea), whose star-shaped bodies are radially symmetrical and are supported by a hard endoskeleton made of calcium salts. Brittle stars are closely related to basket stars, and more distantly related to starfish, sand dollars, and sea urchins.
Brittle Star - an overview | ScienceDirect Topics
Brittle stars arguably are the most diverse group of echinoderms, exhibiting an extensive array of distinct reproductive and developmental modes, which make them difficult to characterize in general terms (reviewed in Byrne & Selvakumaraswamy, 2002; Falkner, Barbarosa, & Byrne, 2013; Hendler, 1991; Mercier & Hamel, 2009; Strathmann & Rumrill ...
