Octopus genome and weird epigenetics another interesting aspect in them and probably related to their intelligence. Octopus can do RNA editing.

Trade-off between Transcriptome Plasticity and Genome Evolution in Cephalopods https://www.cell.com/cell/fulltext/S0092-8674(17)30344-6

• Unlike other taxa, cephalopods diversify their proteomes extensively by RNA editing

• Extensive recoding is specific to the behaviorally complex coleiods

• Unlike mammals, cephalopod recoding is evolutionarily conserved and often adaptive

•Transcriptome diversification comes at the expense of slowed-down genome evolution
