According to biochemist Dr. Bryan Fry, who specializes in the global diversity of venom: “Venoms are poisonous proteins that have specific purposes like paralyzing the nervous system.” We anticipate that by better comprehending the composition and mechanism of venom proteins, we will be able to develop more effective medications for a variety of diseases, including cancer, allergies, and pain relief.

They are not waiting to pounce on you in the tidepools. They prefer to laze around in their tiny den, eat crabs, and lead a tranquil existence by themselves. This is likely the reason why you don’t often hear of someone getting killed or being “attacked” by a blue-ringed octopus. Fortunately for everyone, much of what they bite is something they can control or eat. Only 3 deaths since the 1960s have been linked to a blue-ringed octopus!

The octopus hunts for prey during the day by scuttling across the shallow seafloor and through the coral. It uses a kind of jet propulsion to swim by ejecting water from its syphon. Blue-ringed octopuses can make ink when they are young, but as they get older they lose this defense mechanism. The aposematic warning show deters the majority of predators, but as a precaution, the octopus stacks boulders to block the entrance to its cave. The blue-ringed octopus is not hostile.

13. They have a short lifespan

These creatures only live for two years on average. Both the male and female perish throughout the reproductive process. Shortly after mating, the male passes away. The female lays the eggs, incubating them for six months under her arms. The female doesn’t eat at all throughout this time, and once the eggs hatch, she perishes from malnutrition. For comparison, the giant Pacific octopus lives in the wild for just approximately three to five years.
