Nasty surface conditions and bad viz at Fort Constitution, New Hampshire. Lots of Onchidoris bilamellata, Dendronotus frondosus, tiny sculpin, Tenellia gymnota, Cuthonella concinna, you name it.

I see no difference.

Today's #Nudivember prompt was Onchidoris Bilamellata! Honestly, upon seeing this little guy, this was all I could imagine...

Today's #Nudivember entry is Onchidoris bilamellata, one of those sea slugs that make you stop halfway through drawing and think "Yes, this is a perfect creature."

I think this is a new species for me. I believe this is a Fuzzy Onchidoris (Onchidoris muricata). I've seem similar species before, there are a few tiny white nudibranchs like this, but I'm pretty sure it's O. muricata.

A watercolor sketchbook showing three nudibranches on a white sketchbook, labeled Onchidoris bilamellata (Barnacle-eating Dorid), Fiona pinnata (Feather Aeolid) and Okenia hiroi/Ceratodoris hiroi. The top left creature is covered in brown and ivory bubbly round tentacles. The top right creature is bright pink with petal-like tentacles like a flower, with whitish-blue tips. The bottom is a long ivory/cream and yellow and brown creature with feather-like tentacles and an orange patch internally near the head. A white gel pen and black micron pen are seen below the sketchbook.

#RecordOfTheWeek is a fabulous sea slug, Barnacle-eating Doris (Onchidoris bilamellata), spotted in Penarth by Wynn Griffiths.

This is the first record for Penarth, and the most easterly record for south Wales!

Many thanks for the record & photos, submitted via iRecord irecord.org.uk.

Barnacle-eating nudibranchs were EVERYWHERE at the UNH Research Pier in New Castle, NH. My gloves were leaking, so my hands were very cold (41F 🥶 ) but this was a nice dive!

Onchidoris bilamellata, or barnacle-eating nudibranch moving across a rock surrounded by barnacles. This individual is brown, but they come in white or tan color variations as well. A pair of Onchidoris bilamellata, or barnacle-eating nudibranch moving across a rock surrounded by barnacles. This is a brown color variant and tan color variant side by side. Doris pseudoargus, otherwise known as a sea lemon nudibranch. For some reason, the individuals at this site frequently have a pink tint to them.

I'm a few days late to finding out #nudivember exists but I love it, nudibranchs are so cool. Here's day 4, onchidoris bilamellata (the wikipedia article said they gathered in huge swarms during breeding periods so I gave him a friend <3)

Some images from a dive at Folly Cove in late March. My favorite find was a large mysis shrimp I followed for a bit and managed to photograph in the water column. Nice dive!

Today's #Nudivember species is the barnacle eating dorid, Onchidoris bilamellata. These small, brown nudis are easily overlooked since they're not as flashy as other species.

They can be found in the north as far as the Arctic Ocean, often in dense populations

Love this squishy nudibranch

Today’s nudibranch is Onchidoris bilamellata, a cute blobby golden looking friend who is covered in papilla which look like little bubbles. Its rhinophores look like little blobby horns and it has a little grouping of short (tentacles?) that make it look a little here like it might be wearing a skirt.

Was working again at the beach last night and saw a happy little Onchidoris bilamellata and its eggs with the oysters. Plus some bonus Nucella lapillus and their eggs!! 🦑

A couple of super cool finds by a member of our monthly #rockpoolproject #bioblitz today.
Kilve beach on the #Quantockhills was the location and way out on the low water mark, a nudibranch named, Fuzzy Onchidoris - Onchidoris muricata and a stunning Rose sun star - Crossaster papposus wowed us.
A photo of a tiny white nudibranch (type of sea slug) on a the silty floor of a rockpool. It's main features are the many short blunt blobs covering it. A photo of an orange coloured starfish laying on a rock. The angle of the photo makes this creature appear as a hand with two thumbs and four fingers wearing a prickly textured glove. This starfish has twelve arms in total, the other six arms are just about showing in the background.

#DigitalPainting
Peut-être un des nudibranches qui ressemble le plus à une limace, avec des petites cornes à la place des antennes. La bestiole, dans des tons brun-ocre, est couverte de poils qui ressemblent à de la fibre optique et rampe sur du sable multicolore. Je connais pas son débit de données.
