paper nautilus मीनिंग इन हिंदी

अधिक: आगे

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.
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 " ).
