H. atlanticus is commonly referred to as a "seven-armed" octopus. In the last 27 years, there have only been 3 sightings of this mysterious octopus.
Because of the high percentage of RNA editing in cephalopods, these creatures have suppressed their ability for genomic evolution just to maintain their flexibility in RNA editing.
Dolphins can be pretty brutal when they need to be.
A soft, rubber-like robot powered by farts? It's all real! A team of Harvard scientists has created the first ever octobot, a squishy autonomous robot that's powered by gas under pressure such as hydrogen peroxide.
Octopus ink is one of nature's most theatrical defense mechanisms. But what is it made of?
A resident octopus of the National Aquarium of New Zealand has made the recent headline due to its cunning and brilliant escape from captivity.
Decoding the genome of octopus species has revealed that it's genes are unlike any other animals', even those they are related to. Studies question whether life is possible elsewhere in the universe.
Octopuses have long been hailed as masters of camouflage, able to change the color, pattern and texture of their skin. Now, it seems that these cephalopods not only use their skin as a means of disguise and even communication, but also as a way to "see" light.
The octopus is one heck of an intriguing animal, scuttling along the ocean floor or swimming through the deepest, darkest waters with a beautiful, yet alien-like grace. But can you imagine being one?
