Seen washed up in the intertidal zone at near low tide. This individual measures about 28 cm across.
Not at all certain of this one! Could also be just the "gastrovascular branches" of a sea nettle (no bell or stinging tentacles).
About 6" across. Found washed on top of sea grass, no movement -- perhaps recently dead. Gelatinous, looping/wavy tentacle-like structures attached to a darker-yellow center (just off center in this photo). No obvious organs, etc.
IDed by the naturalist on board. This was a new one for me.
Jellyfish in Pascagoula, MS.
Here's Phacellophora camtschatica, known locally as Fried-egg Jelly and on this site as Egg-yolk Jelly. Seen from above, this jelly really does look like a giant fried egg! This one is about 12" across, a typical size. I saw it looking down from the pier. It was the first I've seen this summer. At times in summer you can see a dozen or so at once in this area.
