That matter is closed, locked up, weighted with lead and dropped in the ocean.

那件事是封闭的、锁起来的、用铅压着然后扔进海里。

That's because the tendons in a bat's talons that close their claw is attached to their upper body, so when they hang, the weight of their upper body automatically pulls their talon closed, locking them in place.

这是因为蝙蝠的爪子中的肌腱与它们的上半身相连，所以当它们悬空时，上半身的重量会自动拉动它们的爪子，将它们锁在原地。
