Deadliest Ocean Encounters

You'd be dead before you even realized what touched you. First, we have the box

jellyfish. You swim past it without noticing. It feels like brushing a rope.

Seconds later, your chest tightens. Your heart starts fighting itself, and usually loses.

Most people never make it back to shore. Second one is the blue-ringed octopus.

You pick it up. Nothing hurts, and that's the problem. Your hands stop moving,

then your lungs forget how to work. You're awake, but trapped inside your own body.

Next is cone snail. It doesn't chase you. It waits. Then something hits

you like a needle. Your muscles silently shut down one by one. Divers don't panic.
