🐢Green sea turtle
绿蠵（xī）龜（學名：Chelonia mydas、英語：green sea turtle），又稱綠海龜、青海龜、石龜（臺羅：tsio̍h-ku）、龜鼊（臺羅：ku-piah）、龜蟞（臺羅：ku-phi̍ah），是海洋中的爬行類動物，是海龟属下的唯一一种。一生中大多的時間都在海中生活，但演化過程中仍然保留了部分祖先的生活方式，所以必須回到出生地上產卵，繁育後代，形成了一種較獨特的生活習性。 綠蠵龜廣泛分布在熱帶及亞熱帶海域中，即約南北緯度60等溫線之間的海域，並在水溫逾攝氏25度的沙灘上產卵。由於牠用肺呼吸，於海中的潛水深度極限約一、兩百公尺。綠蠵龜的主食為海中的海草與大型海藻，因此體內脂肪累積了許多綠色色素，呈現淡綠色，也因而得名。 綠蠵龜已瀕臨絕種，全世界僅剩下約20萬頭產卵母龜，在世界自然保護聯盟瀕危物種紅色名錄中列為瀕危物種。為避免因人類的捕殺及棲地之破壞，所有海龜被均列為瀕危野生動植物種國際貿易公約（或簡稱華盛頓公約）附錄中的物種，也被選為世界自然基金會的海洋十寶之一。
