Why does cuttlefish have ink?
First, why can cuttlefish ink jet?
There are ink sacs in squid, and the cells are filled with black particles. Aging cells gradually rupture to form ink, which is temporarily stored in the ink sac cavity. When cuttlefish meets a strong enemy, it will spray ink with a pen, which will disperse smoke in the water, scaring and confusing the enemy like a "smoke bomb".
This ink contains anesthetic effect! Can anesthetize the enemy's sense of smell, can also anesthetize small fish and shrimp, cuttlefish can seize the opportunity to prey!
That's why it's called squid.
Second, why is cuttlefish called "rocket in water"?
Because scientists get inspiration from the movement of squid, they design and manufacture water jet boats, jet planes, rockets and so on. However, cuttlefish is called "rocket in water", which seems not accurate enough!
It should be said that rockets are like cuttlefish, because cuttlefish has lived in the sea for tens of thousands of years before the rockets came out!
Third, the little knowledge of cuttlefish
