Underwater Strombid Conch Shell Among Encrusting Reef Algae Andaman Sea - 4K 影片檔

A strombid conch shell (Strombidae sp.), likely a spider conch, lies camouflaged among encrusting coralline algae and reef rubble, its form almost indistinguishable from the surrounding substrate. Unlike most molluscs, strombid conchs move using a muscular foot in a distinctive leaping motion rather than a slow crawl, making them among the more mobile reef grazers in the Indo-Pacific. Pink and red encrusting algae and fine sediment cover the surrounding reef structure. 4K, horizontal frame, medium shot, scuba diver POV. Andaman Sea, Krabi Province, Thailand.
