Though they roam the deep sea around the globe, enigmatic giant squid are all part of the same species, new research finds.
The new study reveals that the genetic diversity of giant squid (Architeuthis) is remarkably low — far lower than that of other marine species examined, said study researcher Tom Gilbert of the University of Copenhagen. The findings suggest that the squid intermingle and mate across the globe.
