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 and cuttlefish in small amounts, but specifically several species of the blue-ringed octopus, [1] [2] [5] ... for an average fatality rate of 6.8%. ...
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 ...
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]
The majority of cephalopods do not provide parental care to their offspring, except, for example, octopus, which helps this organism increase the survival rate of their offspring. [110] Marine species' life cycles are affected by various environmental conditions. [111]
The 5-year survival rate of both operating and dissolved co-ops is 100 out of 150 co-ops (for which we have data) or 66.6%. This compares favourably to the 2008 Quebec study of survival rates of co-ops in that province of 64%. By contrast, Industry Canada figures show a 43% and 39% 5-year survival rate for conventional
The southern blue-ringed octopus (Hapalochlaena maculosa) is one of four extremely venomous species of blue-ringed octopuses. It is most commonly found in tidal rock pools along the south coast of Australia. As an adult, it can grow up to 20 centimetres (8 in) long (top of the mantle to the tip of the arms) and on average weighs 26 grams (0.9 oz).
