I was walking down the beach today (Wollongong Australia, near Sydney) and saw this Jellyfish washed up on the beach.
I wanted to work out what type it was but didn't know where to start. I'm looking for a process to determine the category of Jellyfish this is.
I've had a look at this chart:
which tells me it is probably a Catastylus Mosaicus (Blubber fish).
I've also looked at this chart:
which tells me it is probably a Rhizostoma Octopus - Barrel or Root Mouth JellyFish (name only - still a jellyfish).
The biggest identifying characteristic seems to be the eight legs. (Clearly a jelly fish - but still a very confusing trait).
My question is: What are the identifying characteristics of a Jellyfish?
