We enjoyed a little time down under today when I noticed a fresh pile of sand and small rocks pushed out from beneath a larger boulder. Ah ha… I know who’s been renovating.

I repositioned myself for a better look and sure enough... a medium-sized GPO (Giant Pacific Octopus) looking back at me. Well… at least part of one. I could see its siphon and one arm tucked safely inside the den.

Pretty neat watching it breathe. Every time it exhaled, you could actually see a shimmering distortion in the water coming out of the siphon as it crossed the flesh of its arm.

One thing I didn’t notice at the time was all the snails gathered on the right-hand side of the den. Makes me wonder if there’s a connection there too. Leftovers? Clean-up crew? Or maybe they just know a good hiding spot when they see one. Similar to the one I captured a few weeks back and posted about.

Just love the our ‘wet’ coast when it’s like this. Wind and rain that sometimes even goes up. Raw and wonderful.

In Depth: on the Ocean’s Spiky Survivors

Sea urchins are far more complex than they appear at first glance. These images, captured locally in the Pacific Northwest, show the Green Sea Urchin and the Red Sea Urchin, both of which play a massive role in our underwater ecosystems.

Beyond the sharp spines, here are three facts about their unique biology and impact:

-They see and breathe through their feet. The long, flexible tubes visible between the spines are called tube feet. Urchins use these for walking, breathing, and even sensing light. It is as if they have hundreds of tiny eyes and lungs distributed across their bodies.

-They are essentially "immortal." Researchers determined that Red Sea Urchins can live for over 200 years. Scientists proved this by tracking "bomb carbon" signatures from 1950s nuclear testing found in their skeletons. Unlike most creatures, they do not seem to age biologically; a 100 year old urchin is just as healthy and fertile as a 10 year old.

-They are responsible for a delicate ecological balance. Urchins are the primary gardeners of the sea, grazing on kelp to keep reefs healthy. However, when natural predators like sea otters or sunflower stars are missing, urchin populations explode. They turn into spiky vacuums that can devour entire kelp forests, leaving behind bare rock areas known as urchin barrens.

Nature is a delicate dance where one small creature can completely transform an entire world.

Between the vibrant purple and the lime green, which one do you find more striking?

I always love to see the decorator crabs in action. Its amazing how well they blend in to their surroundings. Did you know that if you moved them somewhere else, they would strip themselves and cover themselves with new camouflage within 24 hours. Masters of their domain

90 feet down.

This little sculpin is built to disappear.

Those leaf-like “eyebrows” are called cirri. They help it blend in and feel what’s happening around it.

Big eyes help it pick up movement in the darker water.

Sit still and wait... dinner it coming

Only two of us slipped in between stronger current swings and caught a slack that was absolutely worth it… likely the last good window for a few weeks looking at the charts.

Karen (fish nerd extraordinaire) came through with the find: a juvenile Diamondback Nudibranch.

Neither of us could remember seeing them here before (at least not in recent memory). Ogden, sure… but not this spot.

Either way, always a welcome sight.
So ornate… and even better when they show up where you don’t expect them.

We all voted yesterday and feel that this would work well as our new dive boat. Hopefully there is a air compressor on board :) MV Cascadia
