In the cephalopods, different species of octopuses, squids, cuttlefish and the paper nautilus are deimatic.
2.
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.
3.
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 ".
4.
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 ).
5.
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.
6.
Deimatic behaviour is found in cephalopods including the common cuttlefish " Sepia officinalis ", squid such as the Caribbean reef squid ( " Sepioteuthis sepioidea " ) and bigfin reef squid ( " Sepioteuthis lessoniana " ), octopuses including the common octopus " Octopus vulgaris " and the Atlantic white-spotted octopus ( " Octopus macropus " ), and the paper nautilus ( " Argonauta argo " ).
