Ten Wild Facts About Octopuses: They Have Three Hearts, Big Brains and Blue Blood These bizarre creatures have been around for hundreds of millions of years, and for humans, they've inspired. The Blue Pigment The striking blue color of octopus blood comes from a copper-containing protein called hemocyanin. Unlike the red blood of vertebrates, which uses iron-rich hemoglobin to transport oxygen within red blood cells, octopuses and many other invertebrates, such as snails, spiders, and horseshoe crabs, circulate hemocyanin directly suspended in their hemolymph.
When deoxygenated. An octopus has blue blood and three hearts. But these aren't even the most astonishing things scientists have discovered about these beguiling marine animals.
Here are some additional ways octopuses are keeping researchers on their toes. The blue colour is due to copper, which binds with oxygen and gives the blood a bluish kind of colour, unlike the red colour from iron in human blood. This helps octopuses survive in varied marine habitats, from shallow reefs to even the bottom of oceans.
The three hearts and blue blood are just part of what makes octopuses extraordinary creatures. An octopus has three hearts, facilitating efficient nutrient and oxygen delivery throughout its eight. Here's the weird part-when an octopus swims, the systemic heart stops beating.
Imagine if your heart took a break every time you ran! This is why octopuses prefer crawling along the ocean floor rather than swimming for long periods. Their bodies are built for efficiency in short bursts, not endurance. Blue Blood: Superpower or Weakness? The octopus has nine brains, which it uses to control and manipulate its eight distinct tentacles.
The octopus's hearts, of which there are three, reveal secrets about its evolutionary history while informing our understanding of how it manipulates its environment. to discover the secrets contained in the octopus's three. Octopuses have three hearts, which is partly a consequence of having blue blood.
Their two peripheral hearts pump blood through the gills, where it picks up oxygen. A central heart then circulates. The octopus's triple hearts are just one of many cool things about these animals.
They also have big brains, can change colors, and are great at solving puzzles. Learning more about octopus anatomy gives us a peek into the weird and wonderful world under the sea.
