Maybe someone knows the difference...
when we were down there we saw ~5 per square meter of walnut sized (shell one) jellys, the sting was noticeable, but was a 5 minute deal that a splash of vinegar quickly resolved. this was when we were down for the month of June.
A few years back I got stung by something that looked just like it, and I felt like CRAP for 2 days. this was beginning of July.
Then I hear stories about box jellies that seem to be at a whole different level of severity.
Are we seeing the same thing, just at different maturity levels?
