r/TidePooling

Arrived 1 hour before the negative low tide. Found a cool little cave (first pic).

Hilton's aeolid, horned nudibranch, spotted dorid (or so says iNaturalist). Beautiful foggy day!

In Half Moon Bay CA

Yes, I poked them (gently) with a stick.

Found on Auckland beach. Some sort of sea slug?

Found what appears to be a tagged (00371) ochre sea star today in Sekiu, WA. Tag is a plastic ring pierced through the arm. I can’t find any information online about a related project/ reporting site. Has anyone seen this before or know where to report it to?

Sorry for the shaded picture. Is this a Sea Cucumber? It was still moving whatever it was.

It’s hard to tell from the picture but this bat ray was HUGE

March ‘26
Oregon

two renditions from memory of a jellyfish-like creature we saw swimming. Maybe about 10" long, wriggling through the water. very narrow with transparent body and reddish "eyes". my friend gave it an artistic gred hue but it was not in fact glowing red

trying to figure out if this is tektite, vesicular basalt, or a secret third thing!

it feels dense and heavy but doesn’t weight a lot of that makes sense?

looks like it would feel coarse but is smooth to the touch.

was able to scratch it with some quartz and it left small scratches on both the mystery rock and the quartz.

hope all the info helps! i’m excited to see what people think
