[Cnidaria] Possible box jellyfish

[Campbell, Alexandra Mandina]

I found this video on Youtube and the person who captured the jellies and posted the video wants to know what type of jellies they are. They certainly look like Cubozoans. Unfortunately, there is not much information given about where the jellies wer captured, only that they were found in a river.
Thank you for any information you may have.
