Some recent(ish) #pottery outta the kiln! 1: birdbath, 2: drippy cake stand, 3: vase crackled with sodium silicate, 4: oil bottles.
Ceramic bird bath, mostly blue with some tan and white mottling from another glaze.Ceramic cake stand with vertical grooves carved into the plate edge and the pedestal. Green glaze applied at the top of the grooves with a cream glaze over the whole cake stand, the green glaze has flowed into the groves and left some glaze drips on the edge of the plate.A vase with a noticeable cracking texture through the middle of it. Blue glaze applied to the whole thing and then wiped away where the cracks are, so there is blue at the top and the bottom of the vase and then blue inside the cracks themselves.Four ceramic oil bottles with metal pourers at the tip. The bottle on the left has vertical grooves carved into it and a green glaze flowing down into the grooves with a cream glaze applied over it; the next bottle has vertical grooves carved into it with a purple glaze flowing down into a greenish-blue glaze; the third bottle has a blue glaze at the top and a cream glaze at the bottom; the final bottle has blue glaze at the top and a green-ish blue glaze at the bottom. All four bottles have indents in body of the bottle to make it easier to pick up and hold the bottles.

Spent some time in Bermuda last week with my face in the water. It was pretty lovely, lots of #corals and #seahares and #fishes and even a #nudibranch.
A variety of corals, mostly purple, gray, and light brown, with Atlantic Sergeant Major fish swimming around. The water is aqua blue.A Spotted Seahare in between two Purple Sea Fans.A Zebra Dorid on a sandy sea bottom.A mostly yellow Rainbow Parrotfish behind a coral.

It looks like WoRMS is following the taxonomy in that paper for the Glaucus species, but also this more recent (2019) paper that restored the Glaucilla genus: zookeys.pensoft.net/article/3047...
zookeys.pensoft.net
The extraordinary genus Myja is not a tergipedid, but related to the Facelinidae s. str. with the addition of two new species from Japan (Mollusca, Nudibranchia)
Morphological and molecular data are presented for the first time in an integrative way for the genus Myja Bergh, 1896. In accordance with the new molecular phylogenies, the traditional Facelinidae is...

Spent a couple morning low tides this week in the #tidepools near Morro Bay. Saw some fun stuff, like #nudibranchs, including the tiniest Hopkins' Rose I've ever seen!

The latest update to our free and fun Seek by iNaturalist app adds more than 60k species to its image recognition model! It will now also use your location to provide more accurate IDs! www.inaturalist.org/seek
A hand holds a smartphone in front of a plant with blue flowers. The phone's screen is open to the Seek by iNaturalist app and the app identifies the plant as Blueblossom. 

Next to the phone, text says "New Update. Seek can now identify over 80,000 species & uses your location to provide you even more accurate identifications.

Okay but hear me out: intertidal snails have the cutest faces. #tidepools #snails

One of my fun finds from the weekend in the #tidepools was this baby Giant California Sea Cucumber! I've only ever found them farther north and have only ever seen them full-grown, so it was an unexpected sighting.
A small sea cucumber on a blade of red algae. The cucumber is mottled pink and white on its back, with pointed, bulbous projections. Its underside and tube feet are white.Close up of the organism in the previous picture, focused on its head. You can see the frilly ends of its oral tentacles sticking out from underneath it.

Spent both days this weekend in the #tidepools at a couple of my favorite sites. Things felt a bit churned up from the recent storms, but still spotted many cool creatures, including many #nudibranchs. Here are a few of them.
A Hopkins' Rose nudibranch, bright pink with pink cerata, pink rhinophores, and pink gills.A Black-tipped Spiny Dorid, a white nudibranch with many short white cerata tipped with black, looking like a cute little fluffy sea bunny with long white rhinophores tipped with red and black and a tuft of red gills.A Warty Shag Rug Nudibranch. It's mostly pinkish-peach in color, with peachy cerata with brown splotches on them. Its rhinophores are grayish in color with little "warts" on them. It has a white band going across its head and onto its oral tentacles.A Modest Cadlina Dorid nudibranch, pale yellow in color with tiny, bright yellow dots along its edges.

Six-armed #seastars (Leptasterias spp.) can be pretty amusing when they're regrowing arms. Good for a chuckle in the #tidepools. 📸 1 & 2: shooting stars 📸 3: big-little-big-little-big-litte 📸 4: when every day is leg day 😂

All of these are juveniles, but as adults these different species are very different sizes - so some of these are only going to get a bit bigger, and others will get much bigger!

All are found along the west coast North America (and I saw in California), except for the Purple Sun Star, which I saw in Iceland but is found in globally in northern oceans.

Marine inverts are my favorites, but I do love #birds as well. Some of my favorite finds in Hawai'i were #endemic birds in the forests of Mauna Kea. 1: ʻOmaʻo (Myadestes obscurus) 2: Hawai'i 'Elepaio (Chasiempis sandwichensis) 3: ʻIʻiwi (Drepanis coccinea) 4: Hawaiʻi ʻAmakihi (Chlorodrepanis virens)
ʻOmaʻo perched on a branch. It's a gray bird with a white stomach. Its size and shape are similar to an American Robin.Hawai'i 'Elepaio clinging to a cluster of branches in a tree. It's a small rufous-colored bird with a buff chin and breast. ʻIʻiwi perched on a branch hanging down from a tree. The bird is a honeycreeper, mostly red in color. It has black on the wings, a yellow shoulder, and a lighter reddish-orange dramatically curved bill.Hawaiʻi ʻAmakihi perched on a branch in a tree. The bird is in shadow so the colors are muted, but it's a mostly yellow honeycreeper, with a brigher yellow on its breast and a darker yellow on its head and wings. It has a curved black bill.

There were SO MANY PEOPLE out on the reef, but it was still a nice afternoon in the #tidepools, complete with some #nudibranchs.

There are some very nice low tides coming up at the end of the week and through the weekend, I would recommend finding yourself some #tidepools to visit. Always happy to offer suggestions & tips for #tidepooling.

I usually only find their shells, but spotting a live Appleseed Erato (Hespererato vitellina) in the #tidepools is magical – especially when they have their mantle out like this one. Extra bonus for the cute little amphipod friend whispering secrets.
An Appleseed Erato snail on a blade of red algae. The snail's shell is pink but you can only see a sliver of it, as most of the shell is covered by the snail's mantle, which is golden yellow and brown with black spots, and has fleshy "spikes" coming off of it. The snail's siphon is also visible and below that, its two tentacles. To the top left of the front of the snail is a very tiny purple-ish red amphipod.

Meet the colonial #hydroid Schuchertinia milleri, aka Miller hydractinia, hedgehog hydroid, or (my fave) snail fur. It ranges from Vancouver Island down to Monterey Bay. I've only spotted it a few times while #tidepooling, and it's a treat every time!
