Cephalopod Intelligence
The cephalopod class of mollusks, particularly the Coleoidea subclass (cuttlefish, squid and octopuses), are considered the most intelligent invertebrates and an important example of advanced cognitive evolution in animals. Cephalopod intelligence has an important comparative aspect, because it relies on a nervous system fundamentally different from that of vertebrates.
The scope of cephalopod intelligence is controversial, complicated by the challenges of studying these elusive creatures. Classical conditioning of cephalopods has been reported, and one study (Fiorito and Scotto, 1992) even concluded that octopuses practice observational learning. However, the latter idea is strongly disputed, and doubt has been shed on some other reported capabilities as well. In any case, impressive spatial learning capacity, navigational abilities, and predatory techniques remain beyond question.

awesome work, although there are sum blending errors
