Octopuses- Mysterious and Intriguing Sea Creatures
A Fascinating Look at Octopuses
Existing in the same waterways that sailors and aquatic creatures have traversed for thousands of years, octopuses are mysterious and intriguing sea creatures. They are considered one of the smartest invertebrates on the planet due to their complex behaviour. Here, we take a look at some fascinating facts about octopuses.
Octopuses Have Three Hearts
Octopuses are cephalopods, and they have three separate hearts that all work together to ensure that the animal is getting enough oxygen from its environment. Two of the hearts, called branchial hearts, pump oxygenated blood to the animal’s gills, while the other heart, called the systemic heart, circulates the blood throughout the body.
They May Be Able To Move Inland
Some species of octopus have been observed moving into freshwater environments. This is an adaptation that enables them to live in inland waters that are not always full of oxygen. This means that they may be found in some off water sources such as rivers and lakes.
Octopuses Have Sugary Blood
Unique in all of the animal kingdom, octopuses have sugary blood! This is because they have evolved to cope with cold temperatures since they don’t exercise much in order to conserve energy. The sugar in its blood is an antifreeze-type compound that helps it survive in its environment.
They Have Super Strength!
Octopuses are incredibly strong creatures. The strength of an octopus has been measured up to 300 times its own body weight — they could easily carry a body of a human adult without any obvious effort!
Octopuses Have Incredible Eyes
Octopuses have some of the most advanced eyes in the entire animal kingdom! They can see colors, as well as polarised light. This helps them to distinguish prey, predators, and possible mates.
Conclusion
Octopuses are fascinating creatures, possessing incredible strength, sugary blood, and incredibly advanced eyes. With the ability to move inland, they are unique and diverse creatures that are definitely worth further study!
