Accepted Answer

Dutch Bay in Kalpitiya features extensive intertidal seagrass meadows dominated by spoon-grass (Halophila ovalis) and fiber-strand grass (Halodule uninervis). Green sea turtles (Chelonia mydas) enter these shallows on morning flood tides to graze. Biologists map foraging activity using low-altitude drone photogrammetry flown at 40 meters AGL during calm morning hours (7:30 AM to 9:30 AM). High-resolution aerial mosaics reveal distinctive turtle grazing tracks—clean zig-zag channels cropped through the green seagrass canopy where turtles crop leaf blades, leaving subterranean rhizome roots intact to regenerate.

High-speed motorboat tourism across shallow seagrass flats risks catastrophic hull impacts and propeller lacerations to surfacing green sea turtles.

Seagrass meadows trap suspended terrigenous silt, filtering water before it washes over offshore live coral reefs along the outer maritime shelf.
