Scientists from the Field Museum in Chicago, USA recently discovered that Pacific warty octopuses don’t all have the same appearance, nor do they all live at the same ocean depth.

Their findings, which was published in the Bulletin of Marine Science, indicated that the bumpier the octopus’ skin was, the deeper in the ocean they would be found.

In their research, the team examined 50 Pacific warty octopuses from the Northeast Pacific Ocean, as well as specimens from the University of Miami Marine Laboratory and the California Academy of Sciences.

This isn’t always easy to find out, particularly in the Bocas del Toro province in Panama, where Antillean manatees live in turbid brackish waters, covered by thick aquatic vegetation.

Other methods, like aerial and sonar surveys, and infrared cameras, present logistical challenges and can be costly.
