Blue-lined octopus
The blue-lined octopus is a small sea creature, about the size of a golf ball, that lives in shallow reefs and rock pools in the Pacific Ocean. It is one of the most dangerous animals in the sea, because its bite contains venom that can be fatal to people. It is shy and usually hides, but its bright blue lines are a clear warning to leave it alone.1

Kā to atpazīt
- At rest, its body is mottled yellow-brown with dark blue or black streaks, and its underside is paler.1
- When it feels threatened, it shows bright, iridescent blue lines across its body.1
- It is small, with a mantle (main body) up to 45 mm long, about the size of a golf ball.1
- Its blue markings are lines, not rings.1
- The visceral hump (the bulge behind the head) is regularly pointed.1
Bieži jauc ar: The greater blue-ringed octopus, southern blue-ringed octopus and blue-ringed octopus have circular blue rings rather than lines. The blue-lined octopus is also the smallest of the four species in its genus.1
Indes spēks

Ko nodara tā inde?
Its venom is tetrodotoxin (TTX), a neurotoxic venom, which attacks the nerves. A bite may not be felt at first. After some time, symptoms include loss of feeling in the tongue and lips, muscle weakness or paralysis, respiratory failure (breathing failure), and unconsciousness, which can lead to death.1
Cik bīstams tas ir cilvēkiem?
Bīstamība cilvēkiem: NāvējošsViens no bīstamākajiem dzīvniekiem pasaulē.It is regarded as one of the most dangerous animals in the sea, and its venom can be fatal to humans. At least three human deaths have been reported. The greatest risk is to people who pick it up or touch it.1
Ko tas dara, kad ir nobijies?
When threatened, it displays bright blue warning lines to predators, and it is more likely to flee and hide in shelter than to fight.1
Ja tas iekož
- Spiedošā imobilizācija: aptin stingru elastīgo saiti ap koduma vietu un tad augšup pa visu ekstremitāti, fiksē to ar šinu un turi cilvēku pilnīgi nekustīgu, līdz ierodas palīdzība.
- Zilgredzenu astoņkājis vai konusgliemezis var apturēt cilvēka elpošanu, kamēr viņš vēl ir pie samaņas: sauc palīdzību un esi gatavs veikt mākslīgo elpināšanu, līdz to pārņem ātrā palīdzība.
Vienmēr vispirms zvani uz savu ārkārtas numuru (112, 000, 911). Tie ir vispārīgi pirmās palīdzības padomi, nevis medicīniska konsultācija. Pirmās palīdzības pamati
Esi drošībā
- Nekad neaiztiec, neķer un neķircini savvaļas dzīvnieku, pat mazu, un pat ja tas izskatās aizmidzis vai miris.
- Dod tam vietu. Ja tādu satiec, saglabā mieru, lēnām atkāpies un ļauj tam iet savu ceļu.
- Ja tāds tev iekož: saglabā mieru, nekusties, zvani uz savu ārkārtas numuru (112, 000, 911) vai ātri dodies uz slimnīcu. Atceries, kā tas izskatījās, foto palīdz.
Tas nav nolēmis tevi medīt. Tas izmanto indi, lai noķertu barību vai aizsargātos, un daudz labprātāk paslēptos. Vairāk par drošību

Fakti
A single 25-gram blue-lined octopus carries enough venom to kill about ten adults weighing 75 kilograms each, according to estimates.1
Male blue-lined octopuses bite the female's aorta during mating, injecting TTX. This paralyses her within about 8 minutes, which lets the male transfer his sperm packets safely.1
Hapalochlaena is the only octopus genus known to produce TTX, a toxin thought to have played an important role in the evolution of the species.1
The blue-lined octopus is the only one of the four blue-ringed species with lined blue markings instead of circular ones.1
Blue-lined octopuses are nocturnal hunters, while the greater blue-ringed octopus hunts during the day.1
Its range has been spreading across the Pacific. Warming ocean water may be shifting suitable habitat, and scientists monitor this for public health and safety.1
Mītu grāvējs
Mīts: Because it is so shy, the blue-lined octopus is not really dangerous.
Patiesība: It is extremely shy and usually flees, but its venom can still be fatal to people, and at least three deaths have been reported.1
