There would have been times in life when you have regretted decisions you have made, but I bet they are small fry compared to this fish stuck inside a jellyfish.
Photographer Tim Samuel was snorkelling with local videographer Franny Plumridge when he captured the perfect moment of nature off Byron Bay.
"I have never seen anything like it," he toldAustralian Geographic.
"It seemed completely trapped in there, like it had somehow managed to swim inside and then was unable to back itself out.

"The fish was able to propel the jellyfish forward and controlled its movement to an extent, the jellyfish threw it off balance though and they would wobble around, and sometimes get stuck doing circles.
"I contemplating freeing the fish as I felt bad for it, but in the end decided to just let nature run its course, which was a difficult decision for me to make."
Fish biologist Ian Tibbetts said it was difficult to determine, but the fish could be a juvenile trevally as they have been known to use stingers of jellyfish as shelter.
"It's difficult to tell whether disaster has just struck, or whether the fish is happy to be in there," he said.
"Although by the photographer's description of the fish swimming, my guess is that it is probably quite happy to be protected in there."
