Polyorchis penicillatus, The Red Eye Jellyfish 6/8/2023

This jellyfish mostly hangs out near the muddy bottom, but recent winds must have pulled it closer to the surface.

Video ID: Water sounds. A jellyfish with a ring of red dots around the bottom of its bell and lots of white tentacles splayed out. It contracts and swims up then flips around, dragging its tentacles behind it through sunny green water.

Found some photos I thought I had lost! These are from over ten years ago when I was in Newport and was able to visit the ocean more often. I technically still live near the sea but chronic illness has made it difficult to get the energy to see my invertebuddies since the beach isn’t easily accessible without a car. I do miss my nature walks a lot.

Friends include various (mostly unidentified) jellies, s ctenophores, bladderwrack, and the largest sea lemon nudibranch I had ever seen.

The jellyfish with the red eyes is Polyorchis penicillatus! Folks in iNaturalist seem to think the big beached Schyphozoa is a fried egg jelly and not a Lion’s Mane like I thought. The others I haven’t been able to get identified.

Clione (a sea angel, a swimming gastropod) is also here! Definitely not something I expected to find in the shallows of a bay. I’m guessing most of this stuff was swept up by the tide from deeper more open waters.

@tomnookishot i was on a hiatus for 2 weeks but since u requested jellyfish posting

Ummm

Here are two jellies I briefly did a search on. Not much is said about them in Wikipedia, but they’re both members of the family Corynidae (Meaning “club”, as in the kinda thing that you bludgeon people’s faces in with- which is a pretty metal name imo.)

Anyways, the one on the left is known as the Red-Eyed Medusa (Polyorchis penicillatus), and has a lovely entry on the Aquarium of the Pacific’s website. I’m particularly fond of its bright red ocelli, it’s not unheard of in the Hydrozoan world, but it’s definitely distinguishing.

The one on the right is known as the Hair Jellyfish in Japanese (Spirocodon saltatrix, which is much easier to remember). It’s pretty much everywhere in Japanese jellyfish infoblogs, but I think its hair-like tentacles are tasty looking.

My favourite thing about this family in general though, is how the insides are always so big and prominent. It reminds me of the inside of a pomelo, tbh.

A jellyfish might not be what you think of when it comes to Alaskan wildlife, but spotting this little red-eyed Medusa jellyfish was one of the highlights of my time on the pacific coast. There’s something so mesmerizing about the way these animals move in the water and I feel like their gracefulness is highly underrated!

The red ocelli (eyespots) that you can see around the base of the bell are light sensitive, which allows the jelly to orient itself. It feeds on benthic zooplankton, small crustaceans, and worms. Isn’t it adorable how this little one boops the surface of the water with their bell?

Red Eyed Jellyfish- Polyorchis pencillatus

Salt Creek, August 2019

A choir of bell jellies!! 

Based on the reaction from yesterday’s beachcombing Instagram Story, we went back to Asilomar State Beach to share our findings with Periscope and Facebook Live. 

After spending some time with various algae and moon jellies, we ventured down the beach only to find that Polyorchis bell jellies were also making their way around the Monterey Peninsula! 

Bell jellies are different from moon jellies—they’re a hydrozoan medusa, not a scyphozoan medusa. They’re crystal clear with filamentous guts and gonads, and with conspicuous red eyespots along the eye of their bell, earning them the name “red eye medusa.” 

You never know what you’ll find on the beach!

A weekly recap of taking myself to the water to remind myself I’m allowed to just exist

Video Description: no audio. Title card showing surface of water from beneath it, with sunbeams filtering through and text that says "50+ ocean creatures I saw the last couple weeks in one minute... let's go!". A little yellow larval fish. A series of sculpin a baby sculpin with a fringey tall dorsal fin, an adult with orange dorsal and tail fins, one perched on kelp, two more blending in, a closeup of an eye. A gunnel. A pink sea squirt Boltenia villosa. Some other ascidians. A yellow colonial ascidian Botrylloides violaceus. A large red sea cucumber feeding. Two orange sea cucumber attached under a dock. A california sea cucumber, Apostichopus californicus, in a tidepool. More sea cucumbers under docks feeding. A large white plumose anemone, followed by a small one. A big red anemone. A brooding anemone on sea grass, with babies. An Anthopleura elegantissima with a little red crab perched on it. A series of crabs from big cancer crabs to little hermit and shore crabs. Jellyfish, including Gonionemus vertens, Polyorchis penicillatus, Mitrocoma cellularia. They all have very different movement - the first with tentacles spread wide out, the next with tentacles dragged below, and the third with tiny tentacles and a wide flat body. Next a ctenophore, Pleurobrachia bachei, with its fishing tentacles extended. An assortment of sea stars, from the purple Pisaster ochraceus, to other five armed stars including the blood star Henricia. A green isopod, Idotea, reaches out from on a blade of kelp. A series of seaweed, starting with seaweeds wave off the edge of a dock. There is Fucus surrounded by crustose corralines. Large bladed kelps roll in and away from the rocky intertidal with the swell. A kelp with air sacs like grapes and another ropey kelp with long bristles grow in a tidepool. An overturned gumboot chiton, Cryptochiton stelleri, has gills visible upon closer inspection. Snails crawl in shallow water on a rocky beach. Tube worms, family Sabellidae, grow under the docks, deep red-purple living pom-poms. Spaghetti worms, family Terebellidae cover over a multitude of other inverts living on the side of the dock.

Migrating this series I did on Tik Tok over to tumblr, which unfortunately means scraping the audio off most videos to avoid copyright strikes. If you have any questions, I’d love to talk about these critters!

A hydromedusa (looks like Polyorchis sp.) with a crab larva riding on top and some amphipods hanging out inside. The red dots at the base of the tentacles are eyes!
