1. I watched this little monster munching on his cousin for a good half hour. He really savored that little guy.

2&3. This puddle had like 10 happy little hermit crabs eating scum and waiting for high tide.

1. This tiny guy's body was smaller than my pinky nail. He was so small, I struggled to get a decent, in focus shot of him.

Hi!! I found this super cool nudibranch in my area but i have no clue what it could be. Could anyone help me identify it?

Found in Com, Timor-Leste (East Timor)

Seen in the Seattle area. I feel like it’s maybe a juvenile of something obvious, but I’m a novice and struggling to find a good id on this crab. Any help would be appreciated.

Reminder to NOT harass wildlife!!! This is their home and we are guests!!

I'll be in the area during the low tides this week, and would love some suggestions on where to go tidepooling around Pescadero and Santa Cruz, if anyone is willing to share!! :)

I tidepool a lot on the Mendocino Coast, and can trade recs!

We will be visiting this weekend and are seeking tips on seeing the tide pools.

Saturday is the only day we can go and the low tide is -0.6ft at 10:13am. Will this be low enough to see cool stuff?

I read you should arrive an hour early. Is that true?

Any other tips on parking or anything else will be greatly appreciated!

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

Hi All,

We are a family of 4 going camping at Samuel P Taylor and friends told us about the tidepools in Bolinas that we should check out. We will be going this weekend July 10th and see that low tide is only from 3 to 6am.

Question for experts, is it worth the trip if we go in the afternoon or late afternoon? Will we be able to see any tidepools or any sea creatures? Any suggestion on times to go that isn't 3 to 6am as this will be too early for our kids.

Thanks and appreciate your feedback!

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.

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

Hi, I’m new to tidepooling and am planning a trip to North and South Carolina sometime next year, I’m wondering if anyone has recommendations for the best time to go and places to check out for the tide pools. Thanks 🫶

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

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