Resemblances between cephalopods and fish 
Consider the octopus
Being attacked by an octopus gives the opportunity to marvel at how convergent evolution created similar organs and senses in cephalopod and man.

TLDR
1. Primitive vertebrates have many characters which do not appear to be immediately represented in any obvious precursor, but these characters are nevertheless represented in many primitive vertebrates. Expand
Cognition and Recognition in the Cephalopod Mollusc Octopus vulgaris: Coordinating Interaction with Environment and Conspecifics
TLDR
The examination of data and observations available provide the basis for asking new stimulating questions about the cognitive abilities of octopuses and their allies and open novel scenarios for future comparative research. Expand
The Statocysts of Squid
TLDR
Among all aquatic invertebrates, these sense organs reach the highest level of complexity in octopod and decapod cephalopods, with receptor systems for the detection of both linear (gravity) and angular accelerations. Expand
Prey-handling behaviour of Octopus vulgaris (Mollusca, Cephalopoda) on Bivalve preys
TLDR
It is shown that octopuses exhibited the same behavioural pattern irrespective of the prey species, and when the initial pulling method did not result efficientOctopuses skipped to drilling accompanied by an increase in the handling time. Expand
Body patterns in cephalopods: "Polyphenism" as a way of information exchange
TLDR
The knowledge available on polyphenism in cephalopods: a peculiar characteristic of the behaviour of octopus, cuttlefish and squid that is the mutable appearance of the skin of these species is overview. Expand
Octopuses
TLDR
Octopuses and their relatives, the cuttlefish and squids, form the class of modern cephalopods (coleoids), which have evolved into highly effective hunters which compete with fish in their marine habitat. Expand
The Evolution of Flexible Behavioral Repertoires in Cephalopod Molluscs
TLDR
Evidence is outlined that although competition with vertebrates has left a deep impression on the brains and behavior of cephalopods, the original reorganization of their complex brains from their molluscan ancestors might have been forged in ancient seas millions of years before the advent of bony fishes. Expand
Functional anatomy inspires recognition of Ediacaran Dickinsonia and similar fossils as Mollusca (Coleoidea) and precursors of Cambrian Nectocaridids and extant cuttlefish and squid
A functional interpretation of the problematic Ediacaran fossils Podolimurus and similar organisms such as Dickinsonia indicates that they are hitherto unrecognized members of Mollusca: Coleoidea andExpand
Octopus nervous system
Comparing the body structure and way of life of the modern cephalopods with those of the nautilus and other molluscs reveals how dramatically these animals have changed over the course of evolution.Expand

MUCH information concerning the growth of the shell in mollusca is available, and this indicates the close relation between growth of shell and physiological periodicity of the living body1.

Major divisions of the Cephalopoda
TLDR
Factual and theoretical evidence combine to suggest that many of the features of the Dibranchiata may have developed in their ancestors included in the Nautiloidea, and that many in Nautilus are derived, or possibly connected with, crucial changes in mode of life now known to have occurred in its ancestry.
