| 説明 | Chelonia mydas (Linnaeus, 1758) - green sea turtle at a small patch reef & swimming over a seagrass bed.The turtles & tortoises (chelonians) are an ancient group of reptiles that have a Triassic to Holocene stratigraphic record. Turtles are most easily recognized by their shell - some forms can retract the head & limbs into the shell when threatened, while other species cannot. Their overall body plan has changed very little since the Triassic - a great example of conservative evolution. Chelonians occur in terrestrial, freshwater, brackish-water, and marine settings.Classification: Animalia, Chordata, Vertebrata, Reptilia, Anapsida, Testudines, CheloniidaeLocality: west of North Point Peninsula, eastern Graham's Harbour, northeastern San Salvador Island, eastern Bahamas |
