While the old gas-filled phragmocone couldn't withstand the pressure of the deep ocean, the gladius had no such problem.

In time, the internal shell was streamlined down to a long, chitinous structure, kind of like a backbone, called a gladius.

随着时间的推移，内壳被流线型化为长长的几丁质结构，有点像脊椎骨，被称为短剑。

All squid alive today still have some kind of gladius, while octopuses have a pair of similar structures called stylets.

今天活着的所有乌贼都有某种短剑，而章鱼有一对类似的结构， 称为管心针。

And the squid still swims around with its gladius intact, and the octopus with its stylets -- reminders of the history they share with the shelled creatures of the past.

乌贼仍然完好无损地游来游去，章鱼带着它的探针——它们提醒着过去它们与带壳生物的共同历史。
