HOW COOL IS THIS BOX JELLYFISH!

This Box Jellyfish (Chirodectes) has only been seen twice in the wild, the first was back in 1997, 25 years ago, and the second is this video which was captured by Scuba Ventures - Kavieng in late 2021 near Papua New Guinea!
Interestingly, the original video of this jellyfish captured in 1997 is presumed lost and so this is the only footage of this animal!
