I have attached photos of the jellies in question. Iam visiting Lisbon in the next few weeks and I was wondering if Rhizostoma luteum/ Medusa tambor is common in the area (inside or outside Tagus river) I know Catostylus tagi/Medusa do tejo is very common in the area but I can barely find any sources on R. Luteum so thought to ask here. Are they very rare or are they somewhat frequent, all data is on Medusa do tejo and almost nothing about Medusa tambor in said area. Thanks for anyone that can help
