🦈今天（7月14日）是「#鯊魚關注日」（Shark Awareness Day），雖是海洋食物鏈頂端霸主，但鯊魚卻得努力和漁船保持比社交距離更遠、更安全的距離，以免和人類產生餐桌上的連結。
《自然（Nature）》期刊有研究指出，具有商業價值的鯊魚和國際保護物種的出沒熱點，與延繩釣的重疊率高達76%與64%，並與捕撈量能成正比。
循著產業足跡，台灣也有鯊魚保育責任，國內沿海約有120種鯊魚活動，其中又以象鮫、巨口鯊和大白鯊處境最為難，已被列為禁捕。少到連捕都捕不到的象鮫，被海保署列為優先關注對象，也有專家建議應列為保育類物種。
鯊魚關注日的發起，雖已無從追溯，但保育鯊魚之路漫長坎坷，仍需要你我持續關注。🦈完整報導請見👉https://e-info.org.tw/node/231668

在邁阿密東邊約92公里的巴哈馬群島比米尼（Binimi）海域，潛水員遇到了一隻霸氣十足的無溝雙髻鯊（great hammerhead shark）。影片中會出現幾次「TURN AROUND」提示，看到後一定要記得回頭!
Footage from Jan.30.2019 at German Channel,
dead manta eaten by Tiger sharks and lots of blacktip reef sharks.
Video by Mandy Etpison and Edwin Maidesil
"The adult female manta (F171 Simone) seen dead in the video was first identified early December 2018. She was seen regularly around German Channel since cleaning and feeding, so it is unlikely she died from natural causes. A Japanese liveaboard was first on the scene early morning Jan 30, and the manta was already dead in the shallows. We do not know what killed her, only her left wing was bitten off and large bites taken out of her back at that time. It is unlikely she got tangled in one of the nearby mooring lines, since there were no visible rope/struggle marks on her. She could have been killed by a great hammerhead or something else early that morning, or even by the two tigers that were there, since tigers have been seen hunting turtles at this site before.
By the time we got there at 10.30, several dive groups had already come and gone, but the carcass still looked almost the same. This is because the sharks circled the area, but only came in to take a bite once in a while, as you can see on the video, there was no feeding frenzy, and they came mostly when there were no divers swimming around or snorkelers splashing on top. This footage was taken over a period of 4 hours, with many dive groups coming and going in between. We got the best shark footage when we were alone in the water or could convince other divers to sit down on the sand and stay still. When we left in the afternoon, half the manta was still there, and so were the sharks, but everything was gone by the next morning."
