Scientists have discovered that a pink warty octopus on the ocean floor is the exact species as a smooth-skinned octopus that lived in shallower depths, proving that animals can look different and still belong to the same species

Their study was published Tuesday on World Octopus Day in the Bulletin of Marine Science journal.A warty octopus"If I had only two of these animals that looked very different, I would say, 'Well, they're different species, for sure.
"There's less food as you get deeper in the ocean. So these animals have to work harder to find food to eat. And that means at the end of their lives, they'll be smaller than animals who have more food. If you're a female who's going to lay eggs at the end of your life, maybe your eggs will be smaller," Voight said.Inky the octopus escapes from NZ aquariumMale octopuses transfer sperm packets using a modified arm.
