    綠海龜

    Chelonia mydas, commonly known as the green turtle is a large sea turtle belonging to the family Cheloniidae. It is the only species in the genus Chelonia. The range of the species extends throughout tropical and subtropical seas around the world, with two distinct populations in the Atlantic and Pacific Oceans. They are green because of their fat underneath their shell.

    As a species recognized as endangered by the IUCN and CITES, Chelonia mydas is protected from exploitation in most countries worldwide. It is illegal to collect, harm or kill individual turtles. In addition, many countries have implemented various laws and ordinances to protect individual turtles and turtle nesting areas within their jurisdiction. However, the turtles' populations are still in danger because of several human practices. In some countries, the turtles are still hunted for their flesh and their eggs are collected from nests and eaten as a delicacy. Pollution indirectly harms the turtle populations both on the population and the individual scale. Many turtles die as a result of being caught in fishermen's nets and drowning. Finally, habitat loss due to human development is a major reason for the loss of green turtle nesting beaches.

    綠蠵龜(學名Chelonia mydas),又名綠海龜,是海洋中的爬蟲類動物。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,所以必須回到陸地上產卵,繁育後代,形成了一種較獨特的生活習性。

    綠蠵龜廣泛分佈在熱帶及亞熱帶海域中,即約南北緯度20℃等溫線之間的海域[1],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;背甲顏色則是從棕色有扇形的大花斑到接近墨綠黑等顏色不等。

    綠蠵龜已瀕臨絕種,全世界僅剩下約20萬頭產卵母龜,為避免因人類的捕殺及棲地之破壞,在世界自然保護聯盟瀕危物種紅色名錄中,所有海龜被列為瀕危野生動植物種國際貿易公約(或簡稱華盛頓公約)附錄一中的物種。

    2007年11月15日世界自然基金會香港分會公佈「我最喜愛海洋10寶」公眾網上投票結果,此網上投票為期4個月選出最受歡迎十種本地海洋生物。綠海龜得1695票榮獲「我最喜愛海洋10寶」第二位。
