The blue-ringed octopuses (genus Hapalochlaena) are three (or perhaps four) octopus species that live in tide pools and coral reefs in the Pacific and Indian Oceans, from Japan to Australia (mainly around southern New South Wales and South Australia, and northern Western Australia). This octopus is one of the most venomous animals on the planet. https://www.facebook.com/somersault1824
The common octopus is the most studied of all octopus species. Its range in the eastern Atlantic extends from the Mediterranean Sea and the southern coast of England to at least Senegal in Africa. [wikipedia]
Paper Nautilus (argonauts): Females of this unusual octopus species sequester themselves in thin, translucent shells with which they drift across open seas. They secrete the shells to serve as cases for their eggs but they also function as air-trapping ballast tanks, allowing the cephalopods to hang effortlessly in the water column without sinking. This is the only species known to use surface air bubbles to effectively control their buoyancy. Credit: Robert Sisson / National Geographic
Of mushrooms and women it is said, the most beautiful are the most dangerous. That saying might as well go with octopuses, as blue ringed octopuses are among the most beautiful and colourful octopus species.
An octopus so cute scientists may name it “adorabilis.” Seriously.
Would you just look at him? Sprung to life out of a Pixar movie, the ghostly little fella pictured above was discovered last month by Deep Discoverer, the deep-diving robot that travels with NOAA’s Okeanos Explorer. Spotted 4,290 meters beneath the surface, it’s the deepest observation of a so-called incirrate octopus ever, and it might be a new species.
