00:17While Mother Turtle bides her time, the Cuttle is ready to head in.
00:25Along sandy shores lie one of the most important coastal habitats, seagrass beds.
00:34This is where the cuttlefish are headed.
00:39In it lives a myriad of creatures, and the ones with shell and bone are in danger.
00:48With carbon dioxide increasing in the atmosphere, our oceans turn acidic.
00:53Less carbonate is available to shell builders.
00:57And the acidic water can even dissolve some shells and skeletons.
01:03But seagrass meadows are islands of survival.
01:08They decrease local acidity through photosynthesis and are a last refuge for many in the acidic environment.
