In a never-before-seen phenomenon, a fish commandeered the body of a
jellyfish for protection. Although it is common for fish to swim through
jellyfish tentacles to avoid predators, this particular defense
mechanism has never been seen before.

“I
came across this fish (presumably a juvenile trevally) while snorkeling
along Double Reef on Guam in 2013. The fish swam in and out of the
crown of the jellyfish multiple times over the course of several
minutes. The fish was able to steer the jellyfish as it swam inside,
often turning away from me as I followed. It has been postulated that
the fish is using the jellyfish as a shield to protect itself as it
swims in open waters.”
