But the truth is that octopuses, no matter how big they are, don't prey on humans. In fact, no
Some octopuses may be poisonous, but only a handful cause actual danger to humans. Out of the 300 species of octopuses in different oceans around the world, only four species of blue-ringed octopus pose a real threat to humans. The blue-ringed octopus produces a very deadly toxin containing tetrodotoxin and dopamine.
Luckily, both bites and deaths from these strange creatures are rare, as they usually avoid humans and will only bite if threatened or provoked. There have only been three confirmed deaths from blue-ringed octopus bites—two in Australia and one in Singapore—however, some argue that this number is as high as 11.
A giant Pacific octopus—the largest of the world's 250 or so octopus species—can easily overpower a person. Just one of a big male's three-inch-diameter suckers can lift 30 pounds, and a giant Pacific has 1600 of them.
Despite its impressive size, the giant Pacific octopus poses little threat to humans; it typically avoids divers. However, a bite from a giant Pacific octopus contains toxic venom.
The deadliest Octopus on the world is called the Blue-Ringed Octopus, and can only be found among the warm and shallow waters of the Australian coast.
The story has been called the only substantiated report of a giant squid killing humans. However, other authors have called it into question, considering it an urban legend. In 1978, the USS Stein was apparently attacked by a giant squid.
Her camera captured the curious cephalopod drawing closer and closer, its tentacles widening until it fully embraced her. “It was just crawling on my camera, crawling on my lips, giving me a hug. These huge tentacles were up over my face and mask,” Humphreys said.
But the bright blue coloring says as boldly as it can: don't touch, I'm toxic. Blue-ringed octopuses can kill humans by biting and injecting venom. They bite when they feel threatened, and since we're so much bigger than they are, humans are certainly threatening!
Paramedics are reminding people not to pick up the deadly blue-ringed octopus after a woman survived a rare bite in Sydney this week. The creature is smaller than a 50-cent coin, but its bite releases a toxin that can kill if treatment isn't administered fast enough.
Octopus farming is cruel and immoral and this barbaric practice is condemned by both animal rights activists and many scientists. In addition to being extremely smart, octopus require stimulating and lively environments that are not found on factory farms.
There is a consensus in the field of animal sentience that octopuses are conscious beings — that they can feel pain and actively try to avoid it. Kristin Andrews and Frans de Waal posit in a new report published in the journal Science that many animals, including cephalopods such as octopuses, feel pain .
Although fictional and the subject of myth, the legend of the Kraken continues to the present day, with numerous references in film, literature, television, and other popular culture topics.
In 2004 researchers in Japan took the first images ever of a live giant squid. And in late 2006, scientists with Japan's National Science Museum caught and brought to the surface a live 24-foot female giant squid.
Made of very strong and thick bone, dolphin snouts are biological battering rams. Dolphins will position themselves several yards under a shark and burst upwards jabbing their snout into the soft underbelly of the shark causing serious internal injuries. More than Peas in a Pod.
The male Indo-Pacific bottlenose dolphin is the first known cetacean to die from asphyxiation by octopus, a new study says. He "seems to have been extremely greedy and thought, 'You know what, I'm going to swallow it whole,'" says study leader Nahiid Stephens, a pathologist at Murdoch University in Perth, Australia.
Bored octopuses will often eat their own arms. This is called autophagy.
Dolphins, sharks, moray and conger eels will all feed on octopuses. But the octopus has a number of clever ways to defend itself from attack. The octopus swims head-first, and in times of danger can expel water through the end of its mantle, propelling it like a jet through the water.
The octopuses are not much larger than a ping-pong ball but contain enough venom to kill 26 adult humans. At least three people have died from their bites since the 1960s. Two of those deaths were in Australia. The blue-ringed octopus's neurotoxin helps them catch prey.
