One navy seal vs a 0.2 inch jellyfish

I'm not even kidding there is a tiny jellyfish that is apparently really dangerous

The Irukandji jellyfish are any of several similar, extremely venomous species of rare box jellyfish. With a very small adult size of about a cubic centimetre (1 cm3 or 0.061 in3), they are both one of the smallest and one of the most venomous jellyfish in the world.

They fire their stingers into their victim, causing a condition known in humans as Irukandji syndrome, which can be fatal and difficult to immediately recognise due to the delayed effects of the venom.

Irukandji jellyfish's stings are so severe they can cause fatal brain hemorrhages and on average send 50–100 people to the hospital annually.

Robert Drewe describes the sting as "100 times as potent as that of a cobra and 1,000 times stronger than a tarantula's".

Between 1 January and early December 2020, 23 stings, seven of which required admission to hospital for Irukandji syndrome, were sustained in the waters around Palm Island, off northern Queensland.

It is unknown how many other deaths from Irukandji syndrome have been wrongly attributed to other causes like heart attacks and drownings.
