A marine biologist had a "once in a lifetime" encounter with the rare and stunning blanket octopus off the coast of Australia this month. Jacinta Shackleton, a videographer and photographer, has been capturing wildlife in Great Barrier Reef for the past three years as a content creator for Queensland's Tourism and Events. On Jan. 6, Shackleton posted on Instagram that she had spotted the elusive octopus while snorkeling near Lady Elliot Island. Found living around coral reefs in subtropical and tropical oceans, the blanket octopus gets its name from its cape-like webs enclosing its tentacles, often used to intimidate predators. They are immune to jellyfish stings and will use ripped-off jellyfish tentacles to hunt for prey like small fishes.
