[編輯] 分布 熱帶
同亞熱帶海洋水域。響中國,由山東省到台灣海域,以至中越之間嘅北部灣,都可以發現綠海龜蹤影。


[編輯] 特徵
圖片參考:http://zh-yue.wikipedia.org/skins-1.5/common/images/magnify-clip.png
綠海龜的龜甲 成年綠海龜殼呈黃綠色或者深啡色,長約70至150厘米
,體重約200公斤,也有紀 錄逾400公斤。因為體內脂肪係淺綠色,所以先畀人叫做綠海龜。


[編輯] 食啲乜 綠海龜係雜食性動物
。成年龜以海草同藻類等植物為主,佢哋啲腸特殊細菌,幫助消化食物。成龜間中亦會海綿,水母,墨魚同蝦等海洋無脊椎動物同魚類。海龜仔就鍾意食魚卵,軟體動物,蝦同水母等小動物。

每年六月至十月為綠海龜的繁殖季節。在繁殖季節,綠海龜從數千里以外的棲息地迴游到出生地附近的淺海區交配。母龜會在晚上爬上沙灘,選擇合適的地點挖洞作巢,產下海龜蛋並以沙覆蓋著,然後回到大海中。



海龜蛋在巢中會自然地孵化,通常兩個月左右便會孵出小海龜。溫度對海龜的性別有決定性的影響,溫度較高會孵出較多雌性,反之則會孵出較多雄性的。初生的小海龜只有五厘米長,它們會在陰涼的晚上傾巢而出,一起努力地奔向大海,然後依附在大幅漂浮的海草上隨水漂流。小海龜大約一年後便會游到淺海的棲息地生活。



由於香港的環境不斷改變,近年來已很少發現海龜的蹤跡,因此大家更應珍惜及愛護本港現存的海龜產卵地。若海龜受到干擾而不能在南丫島繼續繁殖,在這一代的成龜死亡後,這種稀有的動物將會在本港消失。



為了保護海龜的產卵地,深灣的沙灘已於一九九九年列為 "限制地區" 。每年由六月一日至十月三十一日,即海龜的產卵季節,禁止未持有許可證人士進入或在該區內逗留。在產卵季節,本署的自然護理員會經常在深灣進行日夜巡邏,以保護上岸產卵的綠海龜及海龜蛋。

 

另外,為了辦認每隻來港的海龜身份及遷游路線,我們去年開始進行標誌放流的研究。在海龜產卵後,我們會以一個刻有獨立編號及地址的細小合金環標誌夾在海龜的鰭狀肢上。標誌放流的研究可使護理人員更容易辦認海龜的身分,有助瞭解來港海龜的種群大小及產卵習性。另外,若當其他人士在外地見到有該標誌的海龜而通知我們,我們便可以得悉海龜棲息地的位置。本港第一隻被標誌的綠海龜編號為 "HK-001" 。我們亦曾將位於不適合自然孵化地點的海龜蛋移走進行人工孵化,並成功孵出超過 100 隻小海龜,大部份人工孵化的小海龜已放回大自然。

漁農自然護理署去年與內地合作追蹤綠海龜,於母龜前肢夾上小合金標誌作記認。海龜在汪洋暢游數個月後,海外研究人員發現,部分已由香港游到海南島,甚至遠至一千八百公里外的日本沖繩島覓食。面對茫茫大海,綠海龜似乎「未驚過」,專家形容牠們的足部像「螺旋槳」,有能力從香港游逾千公里到日本覓食。

我們相信,龜要有效地保護海龜,必須得到市民的支持和合作才可獲得成功。因此,我們的自然護理員曾到訪南丫島的村落,派發單張、貼出告示及向村民與遊人解釋保護海龜的原因及重要性。為了令市民能更加體會到保護野生動物及護理大自然的重要性,我們亦將部分人工孵化的小海龜暫時放養在海洋公園的水族館內,護市民觀察及加深了解海龜。

Green sea turtles, Chelonia mydas, get their name from the color of their body fat, which is green from the algae or limu they eat. Adult green sea turtles are herbivores, meaning that they eat only plants, and therefore do not pose a threat to any other marine animals. Similar to cows, green sea turtles depend on bacteria in their guts for digestion of plant material. Juvenile green sea turtles on the other hand are carnivorous. Their diet consists of jellyfish and other invertebrates. Adult green sea turtles can weigh up to 500 pounds and are often found living near coral reefs and rocky shorelines where limu is plentiful. Although the carapaces of green sea turtles are mostly dark brown in color, they can be covered with patches of algae on which fishes in turn feed. This type of feeding arrangement is an example of symbiosis. Symbiosis occurs when a relationship forms between individuals of two different species for an extended period of time. This particular relationship of the fish eating algae off the turtle's shell would be considered a form of mutualism, a type of symbiosis in which both species benefit from their association. Here, the fish get a free meal, and the sea turtle gets a clean shell.


Green sea turtles are found throughout the world's oceans. Like the other six species of sea turtles, green sea turtle populations are considered either endangered or threatened. Hawaii's population of green sea turtles is listed as threatened under the federal Endangered Species Act, indicating that they may become endangered in the near future. Some populations of green sea turtles in other parts of the world are not as lucky; the populations off the coast of Florida and the Pacific coast of Mexico are already listed as endangered. While tiger sharks are known to feed upon the green sea turtles, man it seems, may pose a greater threat to the animal's survival.

千隻小龜只能活一隻

對 綠 海 龜 而 言 , 生 育 從 古 到 今 都 是 神 聖 的 , 千 隻 只 能 活 一 隻 。 幼 年 綠 海 龜 要 用 上 約 30 年 才 成 熟 , 2 至 3 年 才 繁 殖 一 次 , 平 均 壽 命 50 至 80 歲 。

因 受 發 展 及 捕 獵 威 脅 , 綠 海 龜 數 量 銳 減 , 牠 在 香 港 受 保 護 , 更 是 國 家 二 級 保 護 動 物 。 南 丫 島 深 灣 是 牠 們 在 香 港 的 唯 一 繁 殖 地 , 因 此 1999 年 列 為 「 具 特 殊 科 學 價 值 地 點 」 , 禁 止 市 民 於 6 至 10 月 的 繁 殖 季 節 進 入 , 違 例 者 最 高 罰 款 5 萬 元 。

現 時 全 世 界 有 260 種 龜 鱉 , 海 龜 只 佔 8 種 , 香 港 有 紀 錄 的 則 有 4 種 , 其 中 綠 海 龜 選 擇 在 香 港 繁 殖 。 雄 龜 在 海 中 與 母 龜 交 配 後 並 不 上 岸 , 晚 上 長 達 個 半 小 時 的 挖 洞 產 蛋 過 程 由 母 龜 獨 力 承 擔 。 母 龜 每 次 產 逾 百 隻 蛋 , 每 季 繁 殖 3 至 5 次 , 即 每 年 最 少 也 產 數 百 甚 至 近 千 隻 蛋 , 但 小 龜 存 活 率 低 , 在 自 然 環 境 中 , 千 隻 只 得 一 隻 順 利 長 大 。 不 少 海 龜 蛋 便 被 人 挖 走 , 部 分 小 龜 則 被 捕 食 或 捕 捉 作 標 本 。


Sea turtles are large, air-breathing reptiles that inhabit tropical and subtropical seas throughout the world. Their shells consist of an upper part (carapace) and a lower section (plastron). Hard scales (or scutes) cover all but the leatherback, and the number and arrangement of these scutes can be used to determine the species.

Sea turtles come in many different sizes, shapes and colors. The olive ridley is usually less than 100 pounds, while the leatherback typically ranges from 650 to 1,300 pounds! The upper shell, or carapace, of each sea turtle species ranges in length, color, shape and arrangement of scales.

Sea turtles do not have teeth, but their jaws have modified "beaks" suited to their particular diet. They do not have visible ears but have eardrums covered by skin. They hear best at low frequencies, and their sense of smell is excellent. Their vision underwater is good, but they are nearsighted out of water. Their streamlined bodies and large flippers make them remarkably adapted to life at sea. However, sea turtles maintain close ties to land.

Females must come ashore to lay their eggs in the sand; therefore, all sea turtles begin their lives as tiny hatchlings on land. Research on marine turtles has uncovered many facts about these ancient creatures. Most of this research has been focused on nesting females and hatchlings emerging from the nest, largely because they are the easiest to find and study.

Thousands of sea turtles around the world have been tagged to help collect information about their growth rates, reproductive cycles and migration routes. After decades of studying sea turtles, much has been learned. However, many mysteries still remain.

Most females nest at least twice during each mating season; some may nest up to ten times in a season. A female will not nest in consecutive years, typically skipping one or two years before returning.

Growth & Development

They grow slowly and take between 15 and 50 years to reach reproductive maturity, depending on the species. There is no way to determine the age of a sea turtle from its physical appearance. It is theorized that some species can live over 100 years.

Status of the Species
The earliest known sea turtle fossils are about 150 million years old. In groups too numerous to count, they once navigated throughout the world's oceans. But in just the past 100 years, demand for turtle meat, eggs, skin and colorful shells has dwindled their populations. Destruction of feeding and nesting habitats and pollution of the world's oceans are all taking a serious toll on remaining sea turtle populations.
