This footage is from 27th December 2021 by Scuba Ventures – Kavieng, Papua New Guinea who said about the encounter ‘Saw a new type of Jellyfish while diving today. It has cool markings and is a bit bigger than a soccer ball and they are quite fast swimming‘
Wikipedia tells us ‘Chirodectes is an incredibly rare genus of box jellyfish in the family Chirodropidae. It contains a single species. The first and only scientifically studied specimen was captured from Outer Barrier Reef, northeast Queensland, about 43km off the mainland on May 2, 1997‘
Footage from the 1997 encounter does not seem to exist making Scuba Ventures encounter late last year the only known footage of one. Obviously wikipedia needs to be updated.
Quite nice looking, really.
