Chambered Nautilus
Nautilus pompilius
活了幾億年的活化石。靠著殼裡的氣室來升降,海底最古老的天然潛水艇。
A living submarine from hundreds of millions of years ago. Adjusts its buoyancy using gas chambers inside its shell.
外殼內部被隔成多個獨立的氣室。牠們能透過一根稱為「體管」的組織調節氣室內的水量,藉此控制浮力。
The interior of its shell is divided into chambers. A tube called the siphuncle runs through them, pumping fluid in and out to perfectly control buoyancy.
尚無潛點紀錄。
