The octopus just revealed another one of its secrets: what determines its sex. University of Oregon researchers have identified a sex chromosome in the California two-spot octopus.

That makes it one of the oldest known animal sex chromosomes. The octopus just revealed another one of its secrets: what determines its sex.
