Have you ever wondered about the fascinating world of octopuses? These marine creatures are nothing short of extraordinary, boasting features that seem straight out of a science fiction novel. Let’s dive into the depths and explore the intriguing anatomy of these underwater marvels.
How Many Hearts Does an Octopus Have?
Believe it or not, an octopus has not one, not two, but three hearts! Each heart plays a crucial role in keeping this eight-armed wonder alive and active. Two of these hearts, known as branchial hearts, pump blood to the gills to oxygenate it. The third heart, or systemic heart, circulates this oxygen-rich blood throughout the body, powering up those eight agile tentacles. But here’s a fun fact: when an octopus swims, it doesn’t use its systemic heart. Instead, it propels itself forward by creating water jets with its body mantle. This is why octopuses can tire easily when swimming.
Why is Octopus Blood Blue?
The blue color of octopus blood is due to hemocyanin, a copper-based molecule that carries oxygen. Hemocyanin doesn’t carry oxygen as efficiently as our iron-based hemoglobin, which might explain why octopuses need more than one heart. However, hemocyanin’s efficiency decreases in acidic conditions, which could pose challenges for octopuses as climate change gradually lowers the pH of our oceans.
Does an Octopus Really Have Nine Brains?
Yes, you read that right! Each tentacle of an octopus houses a mini brain that allows it to act independently with remarkable speed and reflexes. In addition to these eight mini brains, there’s a ninth central brain that oversees the entire nervous system and can somewhat override the mini brains when needed. This extensive nervous system requires a lot of energy to function, hence the need for three hearts to pump blood throughout the octopus’s body.
What About Those Tentacles and Suckers?
Octopuses use their tentacles for locomotion and gathering food. They prefer to crawl along the seabed rather than swim. The tentacles are also adept at manipulating objects and can even unscrew jars! During mating, male octopuses use a specialized tentacle called a hectocotylus to pass a spermatophore to the female. Some males even leave this appendage with the female after mating.
Without your parents, who have loved you unconditionally since the moment of your birth, where would you be? Every day when you are young, they do so much for you, and even as an adult, their devotion never ends. Because of this, their particular day, National Parents’ Day, is observed on July 23, the fourth Sunday in July.
National Grandparents Day was observed for about 40 years before Mother’s Day and Father’s Day were founded, but National Parents’ Day wasn’t created until 1994. President Bill Clinton declared it, acknowledging the important role parents play in bringing up and guiding their children. Nicely put!
