Summary
[edit]DescriptionAcanthopleura granulata (West Indian fuzzy chitons) (San Salvador Island, Bahamas) 1 (16131898481).jpg |
Acanthopleura granulata (Gmelin, 1791) - West Indian fuzzy chitons on exposed aragonitic limestone rock surface in the intertidal zone. Chitons are bilaterally symmetrical, dorso-ventrally flattened molluscs having eight overlapping shells (valves) surrounded by a spicule-covered mantle girdle. Most chitons occupy very shallow marine, rocky shore environments, where they graze on benthic algae by scraping the substrate with a radula. Classification: Animalia, Mollusca, Polyplacophora, Neoloricata, Chitonidae Locality: rocky shoreline immediately east of "The Notch", eastern part of the southern margin of San Salvador Island, eastern Bahamas |
