The iridescent enigma: genome evolution and species boundaries of the blue-ringed octopus species complex (Octopodidae: Hapalochlaena)

Brooke Whitelaw examined the evolution of the blue-ringed octopus genus (Octopodidae: Hapalochlaena) species complex. The current state of Hapalochlaena systematics was revealed to be insufficient for the species diversity observed. Furthermore, evolution of the Hapalochlaena genome revealed distinct differences to non-tetrodotoxin (TTX) bearing octopod genomes. This work provides a genetic basis for systematic re-evaluation of the genus, in conjunction with an annotated genome and linkage map for H. maculosa
