Sea wasp (Chironex fleckeri)

The Cubomedusa class, to which this jellyfish belongs, has about 20 species that live in tropical seas, but the sea wasp is perhaps the most deadly of them.

The victim may die from suffocation in about 1.5 minutes, from painful shock in 5 minutes, or may simply choke due to pain and suffocation.
