We saw mating Wonderpus octopuses in Ambon, Indonesia. Is the male or female larger? Also, is one gender more colorful than the other?


There is still a lot to be learned about the Wonderpus octopus. A 2006 paper reported that females are larger than males. However, only two mature samples were measured. The sample size was very small, so the measurements may not be accurate. I've found no recent reports comparing the size of the genders, or describing any color differences between them.
