| 説明 | Protoreaster linckii (Blainville, 1834) - live red knob starfish (aboral side). (captive, Columbus Zoo, Ohio, USA; July 2008)Starfish are vagrant, benthic, mostly-predatory echinoderms. They have a multielement skeleton composed of numerous, small, calcitic plates. Most starfish are pentaradial (they have 5 arms), but some species have 6 or more arms. Many starfish are predators, although some can deposit feed. Predatory starfish include forms that consume prey, usually bivalves, by everting their stomachs through their mouths (= centrally located on the underside) and digest food externally.Classification: Animalia, Echinodermata, Asteroidea, Valvatida, Oreasteridae------------------More info. at:en.wikipedia.org/wiki/Starfishanden.wikipedia.org/wiki/Protoreaster_linckii |
