Jorgen Rasmussen (Singapore) frames an intriguing interaction between a box jellyfish, a fish and an argonaut.

Under the cover of darkness, millions of zooplankton migrate up from the depths of the ocean to feed nearer the surface, luring larger predators such as jellyfish to follow. Enticed, Jorgen dived down 20 metres to watch the spectacle unfold.

In the pitch black, he came across this trio. Dodging deadly jellyfish tentacles, he managed to perfect the lighting of his translucent, reflective subjects and frame these three very different species as they emerged from the darkness.

Inside the umbrella-shaped body of the box jellyfish is a carangid fish, which it may have killed using its powerful stings. Box jellyfish have long tentacles loaded with lethal venom and unlike most other species, they’re active swimmers.

Clinging to the box jellyfish is an argonaut - a small octopus also called a paper nautilus. These often cling to jellyfish to save energy, seek protection from predators or in some cases to eat them.
