Kerið: Iceland’s Volcanic “Eye of the World” That Captivates All Who Visit

Nestled in the rugged heart of Iceland’s volcanic landscapes lies Kerið, a crater lake so mesmerizing it’s often called “The Eye of the World.” What sets Kerið apart isn’t just its geological origins, but its striking resemblance to a human eye with a nearly perfect oval shape, steep scarlet slopes, and vibrant blue-green water that shifts color with the weather and seasons.

Formed about 3,000 years ago during a volcanic eruption, Kerið’s dramatic landscape features rust-red rock walls, bright moss, and lush grass, all framing a lake that is both shallow and intensely colored. The crater is about 55 meters deep and 270 meters wide, making it accessible for visitors who want to hike down to the shore and gaze up at the sky from the “pupil” of the earth itself.

Kerið’s unique beauty has captivated travelers, photographers, and geologists from around the globe. Whether viewed from above or along its shimmering shoreline, it’s easy to see why this natural wonder earned its legendary nickname. In a country filled with stunning scenery, Kerið remains one of Iceland’s most unforgettable sights a reminder that even the earth itself can appear to watch the world with a mysterious, ancient gaze.

An octopus guards its eggs for 4.5 years

Scientists discovered a deep-sea octopus called Graneledone boreopacifica, which guards its eggs longer than any other animal on the planet. After laying eggs, female octopuses do nothing but protect and take care of their eggs. Their brains shut down except for the optic glands, which remain functional. Without these glands, female octopuses would abandon their eggs and resume feeding. The mothers then remain stationary for months to years, depending on the species of octopus. They show no interest in food, even when it's offered to them. Their skin color turns ghostly white from the lack of food. Biologists believe that this behavior is meant to protect their eggs from predators. Octopus mothers are known to lay eggs only once in their lives. The mothers usually die soon after the eggs hatch, which ensures that the mother won’t consume her young.
