I came here just to find the first Father Ted reference. You win!

Cool. (If anything from Sulawesi washes up here, you'll here about it.)

Thanks! Sometimes I'm surprised by what they let me say. And other times I'm surprised by what they won't let me say. E.g., I can chop a person in half with a sword, but I can't swat a dog with a rolled-up newspaper. Apparently censorship is based on how many angry letters they would expect.

Prudes and children are not the target audience. This column appears in a journal for adults, and my target audience is people who don't normally read natural history writing. This one was pretty tame.

Lots of fun (and science!) here. Get your science-based New Yorker comic fix!

Here are some clips of the breach at Stone Lagoon on Sunday. This was shortly after the breach began and shows the breach channel still forming. #Humboldt youtu.be/Ak-Clx8ZU7o

Merry Christmas everyone!🎅🤶🎄
A light tan sea slug with many dark brown spots across its body. The spots have white rings around them, and are biggest on the top and very small around the margin. It has two thick feathery antennae in front, and an out-of-focus rosette of gills at the back. It is crawling from upper right to lower left on a rock encrusted with some kind of brown organism(s). Most importantly, it is wearing a Photoshopped-on Santa hat.

Heh heh... Yeah, this one screamed TAKE A PICTURE!

It's best after a dry period and during calm seas. But it's pretty well protected from moderate surf when the tide is low enough. Need the dry period to firm up the mud at the base of the trail. I bet it's super sloppy right now. Too bad since there are some decent afternoon low tides this week.

Would be a good one.

The best tide pools IMO are at Palmer's Point in Sue-meg SP, but the trail down is pretty steep and gets sketchy at the bottom - but should be fine for an 11 year old. The pools at the north end of Trinidad State Beach have better access, but not a good choice if the surf is elevated.

Good question. At the time - 10 years ago - I was certain it was alive. I believe I saw it moving. But my memory isn't totally clear, so I can't be 100% sure now. My assumption was that the gungy coating on the crab disguised it as not being anemone food, and maybe that would be a safe place to be.

I'm not certain, but I think this is a Pugettia decorator crab. I wouldn't expect it to be comfortable encircled by the tentacles of a giant green anemone, but that's how it seemed. In a #Humboldt tide pool - for #Crustmas.
A crab sitting on top of a green anemone surrounded by the anemone's tentacles seen from above. The crab is triangular and widest at the back, and has at least 3 prominent bumps on each side, and a blunt projection on its face. It is likely a decorator crab, but only has a covering a gungy-looking brown stuff on it. Its walking legs are evenly spread around its body. There should be 8 legs, but only 6 are visible. I assume the other pair is obscured by the crab's claws, which are cocked out in front of it and white at the tips. The anemone is mostly bright green, but the upper half of the tentacles are bluish at the ends, and the lower ones are whitish at the ends. The tentacles are arranged in circles around the central disc, which is a pale greenish blue. There are 4 or 5 rows of tentacles visible around the circumference. The background is a large rock with some red encrusting organisms on it.

A larval herring and a recently transformed herring fry sampled in a tidal pond on #Humboldt Bay for #Fishmas. 🐟
Two fish of the same herring species, but at different stages of development. The fish are next to each other on a white measuring board which indicates that they are between 4 and 5 centimeters long. The lower fish is mostly transparent with a thin black line along its side, a thicker black line along its belly, and a few black spots scattered around its head and body. The part of the belly where the guts are appears silver and not transparent. And the very bottom of the belly is pale orange. Its fins are so transparent as to be invisible. The fish on top is up-side down relative to to the lower fish. Its body has transformed into an opaque silver. It has many very find black specks arranged in rows across its back and on its tail fin rays. It's dorsal fin also has some fine specks along the rays. It's lower body has many almost vertical lines that appear associated with the underlying muscles. Both fish have large silver eyes and black pupils.

Yes - crabs will grow new parts when they molt.

I believe this is a yellowtail rockfish in a #Humboldt tide pool for #Fishmas. 🐟🤿
A rockfish with a bass-like appearance suspended just off the bottom. The bottom is mostly small gray gravel and one clam shell in the lower left. The background is a large rock with patches of pink, red, and brown algae on it. The fish is facing to the right. Its eye is large, and the black pupil is ringed in bright gold. The mouth is closed, but appears relatively large. The fish has prominent scales. The gill cover has some bright yellow highlights. The rest of the head is greening on top, pale gray around the mouth, and with some scattered small brown patches. The body has a pinkish background with many small brown spots below the mid-body, and brown blotches above . The fins are relatively large and unpigmented.

A porcelain crab with an injured "thumb" exposed at low tide in #Humboldt for #Crustmas. 🦀
A crab with relatively very large claws. Each claw looks bigger than the crab's body. The crab is exposed on a rock at low tide. The crab is brick red, but has areas that seem covered with grayish brown hairs and/or other material. The crab's left claw is missing its "thumb" and there is a bit of white meat exposed there. In the frame, the crab is facing up and holding its large claws folded in front of its face. The legs on the crab's left side are hidden behind some dark brownish red algae. Three legs are visible on the right side. The end of each leg has several spikes or hooks - almost like little toes. Its antennae are many-segmented, bright red, and held back behind the crab. The crab's eyes are a dark purple color. The background rock is encrusted with red algae, small barnacles, and there's an oval limpet just above the right "elbow" of the crab.

Heh heh... Coulda put that in the alt text!
