The giant shovelnose ray is a benthic cartilaginous fish species found in tropical and subtropical coastal waters and plays an important role in maintaining marine ecosystem balance. Listed as "Critically Endangered" on the IUCN Red List of Threatened Species, its wild population has declined by more than 80 percent over the past 45 years due to habitat degradation, overfishing and accidental capture.
Captive breeding of the species is highly challenging. In Sanya, the conservation team uses a 13,500-ton aquarium tank, natural seawater and a 24-hour life-support system to recreate its marine environment. Since 2018, the team has conducted long-term scientific care with minimal disturbance to reduce stress on breeding adults.
After continuous monitoring, the team discovered in May that a female giant shovelnose ray was pregnant. The mother ray was carefully transferred to an isolated breeding pool shortly before giving birth, resulting in the successful birth of 12 healthy juveniles.
The young rays can swim normally and feed independently, and are now receiving individual monitoring. Experts said that fully documenting the growth process of giant shovelnose rays from juvenile to adult stages is extremely rare worldwide, adding that the success came from long-term scientific conservation following the species' natural habits.

北京时间7月28日，IFAB（国际足球联合会理事会）站出来为瑞士前锋恩博洛“说话了”。时间回到7月12日，堪萨斯城，世界杯1/4决赛，阿根廷对阵瑞士。第72分钟，阿根廷中场帕雷德斯上前防守，恩博洛腾空倒地。

二 | 葡萄牙籍主裁皮涅罗果断向帕雷德斯出示黄牌，但VAR随即介入。

三 | 慢镜头显示：两人几乎无实质性接触，恩博洛在对方伸腿前已主动起跳。皮涅罗到场边回看后改判：取消帕雷德斯黄牌，转而向恩博洛出示黄牌。恩博洛两黄变一红，被罚下场。最终少一人作战的瑞士加时赛1比3饮恨出局。主帅雅金赛后怒不可遏：“我们因为一条完全无法理解的规则而受罚。”今天，IFAB官方发布文件，对VAR在比赛中介入“误认身份”的规则进行了更为明确的界定要求。

四 | IFAB官方文件原文如下：“非第二张黄牌的判罚，VAR回看仅限于确认犯规球员的身份；犯规本身不能被审查或改判。”换句话说，世界杯上类似恩博洛事件这种“取消防守球员黄牌、把黄牌给到假摔的进攻球员”的操作，以后被禁止了。世界杯开赛前，IFAB扩大VAR权限，新增"误认身份"条款——裁判把牌给错人时，VAR可介入纠正。这本来是为简单场景设计的，裁判认定犯规成立，只是罚错了人。例如：两名同队球员争抢中出现手球，裁判误将黄牌出示给没有触球的球员，VAR回看后，仅把黄牌转移给真正实施手球的队员，犯规性质 “手球” 不会发生改变。但恩博洛事件的实际情况是，原来判的是阿根廷球员帕雷德斯犯规，VAR复核后认定不存在犯规，改判为对方球员恩博洛假摔。犯规性质从防守犯规变成进攻方假摔，领牌方也从防守方换成了进攻方。类似争议事件还在6月13日小组赛美国对阵巴拉圭的比赛中出现：荷兰主裁马克利向美国后卫里姆出示黄牌，VAR回看后确认无接触，撤销里姆黄牌，改判巴拉圭前锋阿尔米隆假摔，并出示了黄牌。IFAB承认世界杯期间这种用法“反响良好”，但在正式修改规则前不能再这么用。未来如何制定，取决于对本届世界杯VAR规则的全面复盘。
