paper nautilus การใช้

In the cephalopods, different species of octopuses, squids, cuttlefish and the paper nautilus are deimatic.
The paper nautilus can rapidly change its appearance : it suddenly withdraws the shining iridescent web formed by its first pair of arms from its shell.
Females of the cephalopod genus " Argonauta " create a papery egg case which sometimes washes up on tropical beaches and is referred to as a " paper nautilus ".
The female of the species, like all argonauts, creates a paper-thin eggcase that coils around the octopus much like the way a nautilus lives in its shell ( hence the name paper nautilus ).
The name " nautilus " originally referred to the pelagic octopuses of the genus " Argonauta ", otherwise known as paper nautiluses, as the ancients believed these animals used their two expanded arms as sails.
