The bite of the Giant Pacific Octopus will not only hurt, but it will also inject venom into its target (although this venom is not fatal). What is this? Thankfully, the Giant Pacific Octopus is known to be rather shy and usually friendly towards humans, rarely using its dangerous features to inflict harm.
When she placed the octopus on her face, it sank its beak into her chin — "not once, but twice. It was like a barbed hook going into my skin," Bisceglia told King 5 News. The wound bled for 30 minutes and was intensely painful.
The octopi's salivary glands produce the venom, and the bacteria gets dispersed through their beak. TTX can paralyze a human in minutes. Due to this paralysis, your body wouldn't be able to get enough oxygen, and death from a blue-ringed octopus would occur.
Blue-Ringed Octopus Venom
The toxin in the saliva paralyzes the prey while the blue-ringed octopus eats it. The TTX that a blue-ringed octopus injects is so deadly that 1 milligram of it can kill a human. It's one of the most potent toxins on earth, and there is no antidote.
Australia's tiny blue-ringed octopus has long had a venomous reputation—one bite can kill an adult human in minutes. But now it seems the rest of the eight-legged species' relatives are not as harmless as once thought. According to a new study, all octopuses, cuttlefish, and some squid are venomous.
Humboldt Squid are more likely to attack objects or species that appear foreign, especially when those objects could pose a potential threat to its shoal (group of traveling squid). There have been confirmed Humboldt Squid attacks on human beings in the past, especially on deep sea divers.
Inland taipan (Oxyuranus microlepidotus)
The most venomous snake in the world is considered to be the inland taipan, endemic to central-eastern Australia. It has by far the highest median lethal dose of venom of any snake, and indeed probably any animal, making it the most toxic.
Their bite is usually painless, but the person bitten will feel numb around the mouth, tongue, face and neck and will feel tight in the chest and may have difficulty breathing. Respiratory failure occurs eventually which leads to death if the person is not resuscitated.
Lobsters, crabs, and octopuses can feel pain and should not be cooked alive, says new report. Lobsters, crabs, and octopuses have feelings and should therefore not be cooked alive, a new scientific report has said.
A shark would win a fight against an octopus. Although we can find cases where an octopus kills a smaller shark, the size disparity is simply too much for an octopus to overcome. Even if the octopus uses camouflage, it can't hide from a shark completely.
"The best way to do this is to bite the octopus between the eyes where the brain is located, it will kill the octopus instantly." It is common practice for fisherman to hunt octopus this way in Hawaii and is often taught when they are introduced to diving as the octopus can be found in shallow water.
Octopuses are playful, resourceful, and inquisitive. Some species cuddle with one another, while others have been known to bond with humans. They are among the most highly evolved invertebrates and are considered by many biologists to be the most intelligent.
It was recently discovered that octopuses, cuttlefish and squid are venomous, capable of delivering a toxic bite.
Bites potentially deadly, but very rare
Like other octopuses, blue-ringed octopuses have a beak, and their venom is secreted from its salivary glands. In the worst case, a dose of the venom can shut down muscles such as those that keep you breathing and cause death within 30 minutes.
A science-based report from the University of British Columbia to the Canadian Federal Government has been quoted as stating "The cephalopods, including octopus and squid, have a remarkably well developed nervous system and may well be capable of experiencing pain and suffering."
While mammals and birds possess the prerequisite neural architecture for phenomenal consciousness, it is concluded that fish lack these essential characteristics and hence do not feel pain.
“Nope! A sound can emit from the shells of the lobsters — a high-pitched sound — but it's due to steam escaping through a fissure in the shell, not the lobsters 'screaming,'” she explained. This doesn't necessarily mean the cooking process is pain-free for the lobster.
Tenderising the octopus:
The best thing you can do is to take a rounded wooden stick (or a meat pounder) and to beat it hard, for about 10 minutes, on its the head (the area around the eyes) and on the tentacles all their way long. This operation will stretch the fibres and make the meat tender.
Australian Box Jellyfish
The box jellyfish is the world's most venomous animal with four species — Chironex fleckeri, Carukia barnesi, Malo kingi, and Chironex yamaguchii — considered highly venomous. The Chironex fleckeri, also known as the Australian box jellyfish is considered the most venomous animal in the world.
In terms of the number of humans killed every year, mosquitos by far hold the record, being responsible for between 725,000 and 1,000,000 deaths annually.
The hedgehog (Erinaceidae), the mongoose (Herpestidae), the honey badger (Mellivora capensis) and the opossum are known to be immune to a dose of snake venom.
Colossal squid live in the Southern Ocean near Antarctica, and it was not until 1981 when the first whole animal was found. It was captured by a trawler near the coast of Antarctica. Since then a few more have been captured by fishermen. You can see one today in a New Zealand museum, but they do not preserve well.
The colossal squid, with its half-ton mass and razor-sharp tentacle hooks, seems pretty fierce. But new research suggests that the school-bus sized cephalopods are actually pretty mellow.
The kraken had very large eyes, and fins protruded from the upper part of its elongated central body. When younger, krakens resembled a pale squid. Their massive tentacles could crush the hull of a galleon. The average kraken was about 100 feet (30 meters) in length and weighed about 4,000 pounds (1,800 kilograms).
