Blue-Ringed Octopus: Hapalochlaena fasciata

Algunas veces la vida puede presentarse de unas maneras muy extrañas.
We saw this octopus in a rock pool at Jervis Bay the last weekend. Is one of the deadly creatures living down under. Su picadura introduce saliva venenosa dentro de la herida de la víctima. Esta saliva contiene un veneno que puede causar parálisis respiratoria. Si no se trata, la muerte puede ocurrir durante la siguiente hora y media. Joder.

Wikipedia: The octopus produces venom that contains tetrodotoxin, 5-hydroxytryptamine, hyaluronidase, tyramine, histamine, tryptamine, octopamine, taurine, acetylcholine, and dopamine. The major neurotoxin component of blue-ringed octopus venom was originally known as maculotoxin, but was later found to be identical to tetrodotoxin,[1] a neurotoxin which is also found in pufferfish and cone snails. Tetrodotoxin blocks sodium channels, causing motor paralysis and sometimes respiratory arrest leading to cardiac arrest due to a lack of oxygen.

O sea: mejor no tocar.
