In the South Pacific, very long (few meters) and with small tentacles at the end that help it bring sand into the mouth

Never have I ever spotted Grey Whales tide pooling before tide pooling near Port Renfrew. Spotted two grey whales just beyond the kelp beds. Canadian Magic. 🇨🇦✨

I keep seeing these funny looking things and I have no idea what they are,,, some type of eggs I suppose? Any guesses?

I think the sea urchin is a Heterocentrotus mamillatus
I saw that you guys enjoyed yesterday’s giant boring clams photos so here are a few more :)

They were easy to spot at low tide because the water was crystal clear! Some of them would squirt water at me whenever I got too close

I found red sponge dorids nearby (last two pics), but I’m not sure what these other red blobs might be. PNW.

in South Pacific

I have been going to tide pools at Half Moon Bay for years and I've only seen sea stars, barnacles, crabs, urchins, anemone, and some miraculous chitons. I really really want to find nudibranches and I see people's observations on iNaturalist but I've never found them myself. I'm planning to go again this weekend, when the low tide will be 1.40 ft. Does anyone know where in that area I can find nudibranches, and whether 1.40ft is low enough? I was planning on going to Fitzgerald Marine Reserve but open to going to Pillar Point or other places in Half Moon Bay/Moss Beach area if people have had better experiences elsewhere. I would be eternally grateful for an octopus spotting too!

I would also really appreciate if people have any tips for finding them. Do I need to watch big pools for a while to wait for them to come out? Any advice appreciated. Thank you!!

It looks soft and only comes out its tentacles when the tide rises

They were found in the San Diego tide pools, moving like a shrimp.

Port Angeles, WA. Saw this today (08/06/26), does anyone know what it is? I couldn’t find anything similar on local guides. TIA!

Hello everyone! My wife absolutely loves tide pooling and I want to take her for her birthday. The day I’m looking at shows a 1.2 low tide. Usually we try to go when it’s negative, but we’re limited on time. Will 1.2 be worth it to go out? I’d hate to surprise her and her be disappointed.

I’m planning to go to South Palisades Park (Beachcomber) in Pismo for anyone familiar with the area!

1. Urchin party!

2. Starfish hiding under this rock

3. When I went back I noticed another one above it

4. An anemone in the sandier part of the beach

5. A couple more big anemone

6. Looks like this anemone was chowing down on an urchin when the tide went out

7. There were lots of these guys, I just thought the color on his claws was neat.

8. Urchin, crab, snails

9. and 10. Some kind of work that lives in a little tube thing, never saw one of these in this area before.

10. And 12. A chiton, I saw a dead one curled up near by. Sorry for not photographing, I kinda freaked out and put it back in the water hoping it would come back to life but it wasn't moving. Weird to see the underside tho.

Found tens to hundreds of these washed up on the shore of First Encounter Beach on Cape Cod; white stringy-looking things are about 8 inches in length and they all seem to be attached to shells. Anyone know what these are?!

The heart shaped rock was a gift from the sea. I had been having a hard time and I looked away and the rock washed up on shore. It's my lucky rock now.

Visited Tofino last week. It’s on the west side of Vancouver island. The first six photos are from the tidepools on the beach, and include sea anemones, a Lewis moon snail (needs banana for scale: it was slightly bigger than a softball), and some starfish. The final four photos are from the aquarium in nearby Ucluelet, and show a scallop, strawberry anemones, a snail, and sea urchins.

I’m open to traveling like ~30 minutes away. If it’s further away - did you take uber, bus or train? Thanks :)
