The Blue-ringed octopuses (Also known as genus Hapalochlaena) are three different types of Octopus species that mainly live in tide pools and coral reefs. They mainly reside in the Indian and Pacific Oceans because of the many different reefs and other low tide areas of water. They are considered one of the most dangerous sea creatures in the world, even though they are minuscule in size. They have Brown patches on their body and when agitated the brown patches become darker and soon they become blue-rings that cover the body. The venom that is released from this sea creature is very deadly to other sea creatures including small crabs, and shrimps and the venom can also be strong enough to kill a human.
One cool fact about the Blue-ringed octopus is that if it loses one of its eight arms it can grow it back in a period of about six weeks.
The Cardiovascular system (Also known as the circulatory System) of the Blue-ringed octopus is actually quite intriguing. The Octopus has one main heart known as the systemic heart, and two smaller hearts near its gills. The two smaller hearts pump blood to the gills where it dumps its waste and loads up on oxygen, then pumps the fresh oxygen-rich blood back to the main heart. Then the main heart pumps all of the fresh blood throughout the octopuses body.
One cool fact about the Octopuses cardiovascular system is that the blood pumped through the body is blue, and even when the blood is released from the body the color of the blood remains blue. This is due to a protein called hemocyanin which helps create and keep the blood blue.
