In the 1983 James Bond film Octopussy, the blue-ringed octopus is the prominent symbol of the secret order of female bandits and smugglers, appearing in an aquarium tank, on silk robes, and as a tattoo on women in the order. [28] [2] The Adventure Zone featured a blue-ringed octopus in its "Petals to the Metal" series. [29]
The greater blue-ringed octopus, despite its vernacular name, is a small octopus whose size does not exceed 10 centimetres (3.9 in), arms included, with an average weight of 80 grams (2.8 oz). Its common name comes from the relatively large size of its blue rings (7 to 8 millimetres [0.28 to 0.31 in] in diameter), which are larger than those of ...
All octopuses have venom, but few are fatally dangerous. The greater blue-ringed octopus, however, is considered to be one of the most venomous animals known; the venom of one is enough to kill ten adult humans. [3] It uses the neurotoxin tetrodotoxin, which quickly causes respiratory arrest. Estimates of the number of recorded fatalities ...
What makes this octopus famous is its venom. Saliva glands of the southern blue-ringed octopus produce the deadly neurotoxin, maculotoxin. [10] The neurotoxin, tetrodotoxin (TTX), is secreted in the posterior salivary gland, which is located in the intestinal blood system of the octopus. This may provide the toxin into its bloodstream.
The blue ringed octopus (Hapalochlaena maculosa) is only 10 cm long but carries enough tetrodotoxin venom to kill 26 adults, although records indicate it has only killed 3 humans. [60] [61] [62] There is no blue-ringed octopus antivenom available. [63] Very few cases of children being envenomated are reported. [64]
Although tetrodotoxin was discovered in these fish, it is found in several other animals (e.g., in blue-ringed octopuses, rough-skinned newts, and moon snails). It is also produced by certain infectious or symbiotic bacteria like Pseudoalteromonas , Pseudomonas , and Vibrio as well as other species found in symbiotic relationships with animals ...
Venomous octopus Local envenomation at site of bite wound. Extremely painful and may result in death. The Blue ringed octopus may on rare occasions bite a diver. Found only in parts of the Pacific Ocean from Japan to Australia. The octopus is unlikely to be aggressive, and is not likely to bite unless handled.
Many species of octopus, squid, and cuttlefish make use of venom when hunting their prey. The blue-ringed octopodes ( Hapalochlaena spp.) produce tetrodotoxin , which is extremely toxic to even the healthiest adult humans, though the number of actual fatalities they have caused is far lower than the number caused by spiders and snakes, with ...
