The major neurotoxin component of the blue-ringed octopus is a compound originally known as "maculotoxin"; in 1978, this maculotoxin was found to be tetrodotoxin, [17] a neurotoxin also found in pufferfish, rough-skinned newts, and some poison dart frogs; the blue-ringed octopus is the first reported instance in which tetrodotoxin is used as a ...
Grimpoteuthis [1] is a genus of pelagic cirrate (finned) octopods known as the dumbo octopi. [2] The name "dumbo" originates from their resemblance to the title character of Disney's 1941 film Dumbo, having two prominent ear-like fins which extend from the mantle above each eye.

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 ...
To understand the inner details of octopus lives, researchers dived for about a month at a reef off the coast of Eilat, Israel, and tracked 13 octopuses for a total of 120 hours using several cameras.
The video shows the octopus spewing ink as it swims close to the camera. The seal, however, seems undeterred by the ink and quickly catches up with the octopus.
