Three Hearts - Octopuses

 


Octopuses Have Three Hearts

An octopus may not be known for having a "big heart," but it certainly has multiple ones—three, to be exact. Two of these hearts pump blood to the gills, where it gets oxygenated, while the third circulates the oxygen-rich blood to the rest of the body. 

Unlike humans, octopuses have copper-based hemocyanin in their blood, making it highly efficient in cold, low-oxygen environments. This unique three-heart circulatory system supports their active and complex lifestyle—whether they are hunting prey, solving puzzles, or escaping predators. 

Combined with their mastery of camouflage and intelligence, octopuses are perfectly adapted for life in the deep sea.

I rinsed the teapot gently, as though preparing a sacred ritual. I boiled just enough water for two hearts, added two crushed cardamoms—like secret whispers—and a spoonful of tea leaves, rich and fragrant. As the aroma filled the air, I poured in the milk, letting it swirl like a tender embrace. When it was ready, I carefully strained the tea into a cup and then poured it into two glasses—one for me, and the other for the soul who completes me. I walked over and offered the glass to my everything—my love, my heartbeat, my calm. We sat together in the gentle hush of morning, sipping slowly. The tea was warm, but the moment was warmer. A stolen slice of time… where nothing else mattered. No rush, no noise, just us. A quiet closeness. A thousand unspoken words floating in the steam. And in every sip… love. "The first c...

A flower vase

Image
A flower vase, filled with various flowers such as daisies, lilies, roses, daffodils, tulips, etc., brings different fragrances and thoughts to anyone who smells and sees them. The vase was placed on the reception counter, not only catching everyone's eyes with the beauty of each petal but also kept in half a jar of water to stay fresh throughout the day. They were bathed in the sunlight streaming through the window. In that transparent jar, a very tiny fish swam, mimicking a stream. The subtle sounds of the receptionist breathing in and out created a soft murmur, while the air conditioner added an eerie ambiance. The vase spread joy and happiness throughout the day. The scent of each flower spoke of life's serenity. As days passed... The flowers began to dry... Their life was stifled by the room's oppressive atmosphere... The clock's ticking was incessant... Its three hands moved restlessly from one digit to the next... Petals from the dried flowers began to fall from ...
