Octopus bimaculoides

Albertin et al. sequenced genomic DNA from one living male Octopus bimaculoides and used 12 RNA transcriptomes from tissue and developmental samples to annotate the assembly. These are present-day research samples, not dates for species origin, fossil first appearance or complete geographic range. This navigation entry is not a phylogeny or a complete taxon dossier.

The Octopus bimaculoides genome and 12 RNA transcriptomes document gene-family expansions and rearrangement. The study found no evidence for whole-genome duplication but did not exclude duplication followed by extensive gene loss; these samples do not date octopus origins.
