The brown and white striped pattern on pygmy zebra octopuses (Octopus chierchiae) varies between individuals, which could aid their conservation
A monthly celebration of the biodiversity of our planet’s animals, plants and other organisms.They found that each of the 25 octopuses had a unique configuration of stripes.
Volunteers who were shown photographs of the octopuses could even identify whether the images were of the same animal or two different ones, with an average accuracy of 84.2 per cent. This suggests that individual pygmy zebra octopuses could be repeatedly identified and monitored in the wild over time, potentially aiding their, the researchers write in their paper. These octopuses are rare and delicate, so should ideally be studied in a way that doesn’t remove them from their natural environment, they write.
While the stripes on pygmy zebra octopuses appear to vary between individuals, why they have these stripes at all is unclear. “The fact that they can turn the stripes on and off and even do it unilaterally suggests to me that they are used in communication or at least to make signals more obvious,” says
