This animation was used in the following video by The Nature of Science:
The Irukandji jellyfish, fish for fish using deadly extendable arms that are covered in venomous stinging cells. As it swims along, this tiny jelly extends its tentacles and twitches them much like a fisher or fly-fisher would to attract prey in the water. The balls of venomous stinging cells (nematocysts) act like a lure and attract fish. When contact is made with the tentacles the venomous harpoons are fired into the prey which paralyses them.
