The blue-ringed octopus, despite its small size, carries enough venom to kill 26 adult humans within minutes. Their bites are tiny and often painless, with many victims not realizing they have been envenomated until respiratory depression and paralysis begins. [ 11 ]
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.
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 ...
Native to the Pacific Ocean, the blue-ringed octopus is small and super cute. Those blue rings are beautiful and mesmerizing, but just look, don’t touch. ... And its venom is huge overkill for ...
Blue-Ringed Octopus The blue-ringed octopus carries Tetrodotoxin, a neurotoxin just like pufferfish. However, the Blue-Ringed octopus contains enough toxins to kill a human.
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 ...
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 ...
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 ...
