Chiton w blue lines on its plates. S pink coiled worm on one plate
Oval shaped Chiton w green girdle, overlapping plates are orange to brown w white curvy lines
Green-brown girdle w nubby protrusions. Plates are olive green w cream colored triangles
Chiton w Speckled girdle w yellow spots, plates mostly brown w thin blue lines and three plates have narrow white triangle
Today’s minus tide superstars are the chitons! #marinelife 🦑 #intertidal #minustide #kachemakbay #alaska #tutkabay
it looks so good! I'd definitely try making my own if you ever did write up a pattern - the world needs more yarn eels!
wow I love this so much!! what pattern did you use?
Digital illustration of a rainbow trout, recolored with the colors of the bi pride flag, with dark blue on top, pink along the side, and deep magenta along the belly.
Digital illustration of a rainbow trout recolored with the colors of the trans pride flag with light blue along the top and belly, pink along the sides, and a white stripe along the lateral line.
Digital illustration of a rainbow trout recolored with the colors of the lesbian pride flag with oranges along the top, purples along the belly, and a white stripe along the lateral line.
To celebrate the start of Pride Month, here are some Pride rainbow trout! Happy Pride everyone! #SundayFishSketch
Our #FishOfTheWeek this week is… the Australian Lungfish (Neoceratodus forsteri) 🐟

Small, perky snail with head poking out between its two shells. The snail has a pair of long, tubular tentacles. The shells are like clam shells, except they are vivid green. The hinge is at the top.

In this photo, the snail is lying on its side with the hinge of the two shells pointing towards the camera. The shell and snail are both very bright green. The snail has white blotches on its back.

We’ve looked at snails with one shell and slugs with no shells. Now let’s have a look at a snail with two shells, because Nature laughs at our puny attempts to pigeonhole.
In today’s #AtoZ – J is for Julia (Juliidae) (1/9)

New #megalodon paper! 🦈
This work further applies the new "slender" hypothesis to some of the shark's basic biology, including suggesting a lemon shark-like body.
Congrats to the authors! Will probs dedicate my 1st website blog to my thoughts on this paper: palaeo-electronica.org/content/2025... 🦈
Photographs of the holotype of Barbodes klapanunggalensis sp. nov.
Another new cavefish just dropped!
Barbodes klapanunggalensis, a new species of blind subterranean fish (Cypriniformes, Cyprinidae) from Klapanunggal karst area, West Java, Indonesia, with notes on its conservation

A photo of a small sea slug that is primarily green with pink tipped cerata. The green colour comes from the stolen chloroplasts that the slug uses to photosynthesise and produce sugars. It has two small black “eyes” on its face with a yellow patch below.
So this little #SeaSlug is a type of sap sucker in the genus Costasiella. These are not technically #Nudibranch and belong in the super order of #Sacoglossa. They perform kleptoplasty where they steal chloroplasts from their Avrainvillea algae host and utilise them for photosynthesis

Career goals I didn't know I had!
Ancient Egyptian ivory sculpture of a leaping dog. The ivory is now biscuit coloured. Dimensions: 18.2 cm (L) × 6.1 cm (H) × 3.6 cm (W) A lever under the dog’s chest opens and closes the mouth. The inside of the mouth is red. The eyes are outlined in black. Dated Late Dynasty I8, I400-I350 BC.
Something lovely for the weekend! A very good boy! 🐾🐕😍
An amazing c. 3,400 year-old ancient Egyptian dog carved from ivory. This leaping hunting dog opens and closes its mouth, as if barking, by using a lever below its chest. 📷 by me

A mounted Ichthyosaur skeleton from the perspective of the tip of the nose.
How often do you see an ichthyosaur fossil from this perspective? They are so frequently preserved flattened that it is easy to forget how massive they must have been. This specimen is at in the Evolutionsmuseet in Uppsala #Fossilfriday

A close up photo of a Sea Slug that is primarily green - its rhinophores are dark blue. It has some red markings around its head and some small spots on the body
Last #Nudibranch for the year - this is Nembrotha milleri from the Philippines. Have a great day wherever you are - and may 2025 be a Nuditastic year for you.

Not to mention the "volunteer" opportunities that require you to pay for the experience, or internships that offer no money beyond free accommodation. So much information about breaking into areas like marine science focus on the value of experience, but much of that is behind a significant pay wall
Pregnant Ichthyosaur (Stenopterygius quadriscissus) fossil. This Ichthyosaur has been preserved with the skeletons of unborn young inside. A fourth may have just been born - its skeleton can be seen below the tail. Ichthyosaurs were marine reptiles. This specimen lived between 187 and 178 million years ago.

Bones can fossilize, soft tissues can fossilize, tracks, burrows, and faeces can fossilize — even joyful moments can be preserved in the fossil record !

Really interesting article! I had no idea there would be so little overlap in the species detected with each method 🐟
Female snailfishes of different Careproctus species. From the top (A) C. melanurus, (B) C. colletti, (C) C. furcellus, (D) C. simus From the paper: Gardner, J. R., Orr, J. W., Stevenson, D.

Snailfishes in the Careproctus genus lay their eggs in a place which is well-protected and well-aerated - in the gill cavities of king crabs. 🦀
These crabs essentially become mobile incubators for snailfish eggs

a pine tree with bugs hanging all around it. at the very top is a dragonfly-like meganeura with open wings, circling the base is the giant millipede arthropleura. on the branches sit various insects and circular pine cones.
Have yourself a merry little Carboniferous.
