一 | 据媒体报道，夏威夷最后一棵金冠树耳蜗（Achatinella apexfulva）最近死亡，这意味着该物种也已经灭绝。    During a training exercise in the ocean on Sunday, a lifeguard from Long Island, who was playing a victim, was attacked by a shark, the local media reported.,The lifeguard reportedly fought the animal off with his bare hands. During his scary encounter with the 4- to 5-foot-long (1.2-1.5 m) shark, Smith Point Beach lifeguard Zack Gallo was bit in the chest and right hand, Suffolk County Executive Steve Bellone reportedly stated at a news conference.,"He was playing the role of a victim, and in the midst of that, actually became a victim when this shark bite occurred,” the official noted.,Bellone reportedly claimed that Gallo defeated the shark by "punching down" on it. According to the report, the lifeguard's hand injuries "occurred as he was beating off the shark," and after that interaction ended.",The lifeguard reportedly was "bleeding significantly" when other guards who were already in the water for the exercise raced to aid him, but the victim surprisingly managed to get out of the water unaided.,After being bandaged, the injured lifeguard was brought to a nearby hospital.,“Fortunately, he is doing well,’’ the official said. “He’s in very good spirits at Southside Hospital … getting some stitches.",The attack caused the beach to be closed. Later, the same shark may have been spotted by police using a drone to monitor the ocean, according to the report, but the authorities could not determine if it was the same shark or not.,Even more to the news about sharks getting dangerously close is that Cupsogue, a second beach east of Smith Point, was also reportedly closed on Sunday "due to dangerous marine activity.",On July 1, a 57-year-old swimmer in the area of Jones Beach in Nassau County experienced a "possible shark bite," the police said. This incident prompted the authorities to increase beach patrols ahead of Fourth of July.,Shark attacks on Long Island are "very rare," but recently they have reportedly become more frequent. More shark sightings have occurred in the last two years than in the prior ten years combined.,Two Women Killed in Shark Attack Off Egypt's Red Sea CoastYesterday, 13:00 GMT。据报道，这只名叫“乔治”的夏威夷树蜗牛于今年1月1日死亡，享年14岁。14年来，“乔治”没有找到配偶，“乔治”的死意味着我们目睹了另一个物种的灭绝。夏威夷树蜗牛最明显的特征之一是蜗牛壳顶部的金黄色区域。该物种最初分布在夏威夷群岛的瓦胡岛上。它在夏威夷的繁荣时期非常丰富。1995年以后，夏威夷蜗牛在外来蜗牛的入侵下几乎灭绝。维基百科的图片显示，人口减少的主要原因之一是“玫瑰卷”（玫瑰橡实蜗牛），一种中等大小的蜗牛，属于橡实蜗牛属，原产于美国。

二 | 本种是捕食其他蜗牛的食肉动物。

三 | 玫瑰卷之所以被引进，是因为它想控制入侵非洲蜗牛的数量，但没有考虑。夏威夷蜗牛濒临灭绝。这就是为什么夏威夷至少有8种当地蜗牛灭绝的原因。1997年，最后10只蜗牛被送到夏威夷大学的实验室进行人工繁殖，但最终，除了乔治以外，所有的蜗牛都死了。在此之前，国际自然保护联盟（IUCN）已将该物种列为极度濒危物种。据了解，科学家们已经提取出“乔治”身体组织用于制冷，期待有一天“复活”乔治。一些灭绝物种（百科全书）：1681年的渡渡鸟灭绝；1768年的海牛灭绝；1800年的恐怖鸟类和蓝马羚羊灭绝；1844年的海鸟灭绝；1875年的南极狼灭绝（生活在地球最南端的犬科动物）；1880年的美国缅因州黄鼠狼灭绝；1880年的牙买加仓鼠灭绝（关于区域性灭绝；3年内灭绝；1890年澳大利亚兔子灭绝；1900年昆士兰毛鼻袋熊区域性灭绝；1900年圣诞岛虎头鼠灭绝；1901年艾米旱獭灭绝；1902年澳大利亚白足旱獭灭绝；1903年加利福尼亚南部猫和狐狸灭绝。利福尼亚；1910年西部袋鼠灭绝；东部袋鼠灭绝；1911年白狼绝对灭绝（唯一的纯白狼）；1918年卡罗莱纳鹦鹉灭绝（北美鸽子）；1914年（十亿不到一个世纪）；1915年基奈山狼灭绝（最大的狼亚种）；佛罗里达黑狼1917年灭绝的狼；1920年灭绝的新墨西哥狼；1922年灭绝的野蛮狮；1922年灭绝的中国犀牛（区域灭绝）；1926年澳大利亚海豚脚袋鼠灭绝；1927年澳大利亚袋鼠灭绝；1930年澳大利亚大兔袋鼠灭绝；灭绝1930年的新南威尔士白袋鼠；1937年的巴厘虎灭绝（最小的虎亚种）；1948年的印度亚洲猎豹灭绝（区域灭绝）；1950年的喀斯喀特棕狼灭绝；墨西哥灰熊绝对灭绝；1970年的德克萨斯红狼灭绝；台湾云豹灭绝1983年；1987年危地马拉鹦鹉灭绝；1997年左右欧亚貂灭绝。
