i keep forgetting about wander wednesday JSHSHSH

[thelazzyblogzz]

Tonight is the night I finish wander over yonder!!! Happy wander wensday!! Of course, I’ll still draw abt Wander and his friends on wensdays, but now I will be fully caught up to the show!! :} just 2 more episodes to go-

[madd-draws]

POV: you got Wander's order wrong and gave him a double pickle cream pie (he insists it's not that big of a deal)

The second time for Wander Wednesday.

Happy Wander Wednesday, Wanderers! Here are my Wanders for today!

- Wander smiling. - Wander and Janet. (She’s cuddling him as a friend.)  - A memory redraw of Wander from The Egg.  - A hatless Wander. (Because I didn’t know what else to draw.)

Holy shit.

[wtfdumb]

happy wander wednesday guys!! we have a special guest today, the one and only commander peepers‼️ now i need to learn how to draw lord hater :]

[the-wandering-star-nomad]

My post for Wander Wednesday! I made this on Picsart!

[insertdisc5]

cha girl forgot her business cards at home so i got new ones printed posthaste

[wherefancytakesme]

It’s been that long since I started college and the show’s been gone for half that time-

Wet Beast Wednesday: chitons

For last week's Wet Beast Wednesday I talked about a weird invertebrate whose name starts with "c" so this week I'm gonna branch out from that and talk about a weird invertebrate whose name starts with a "c". Chitons are marine mollusks of the class Polyplacophora that bear a resemblance to limpets, but have a segmented shell that allows for more flexibility. They are named after a form of clothing worm by the ancient Greeks.

(image id: a chiton. It is an oval animal with a flat shell composed if 8 overlapping green and white plates. Surrounding the shell is brown, soft tissue)

Chitons are similar in appearance and ecology to limpets, though they are not closely related. The shell of a chiton is made of 8 plates called valves. Valves are the name of any mollusk shell that is divided into multiple pieces. Most mollusk shells are made of one continuous piece and the only ones that have valves are the chitons, bivalves, and a few weird snails. The valves of a chiton overlap slightly, allowing for flexibility while still giving protection. Chitons can curl up into balls and flex backwards to move over concave surfaces that limpets wouldn't be able to. The valves are imbedded in and held together by a thick, muscular ring called the girdle that encircles the body. In most species, only the sides of the valves are covered by the girdle, leaving the rest exposed to the water. A few species cover more or all of the valves with the girdle. When a chiton dies and the girdle decays, the valves will separate. Individual valves sometimes wash up on beaches and are called butterfly shells due to their v-shaped appearance. The shell is used for defense. Chitons can curl up in a ball when not attached to a rock. If one is attached to a rock, it can suction on, presenting predators with no good way to attack its soft underbelly. Some species have spikes, bristles, or other ornaments on their valves and girdles that can provide additional protection.

(image: a chiton curled up into a ball. Its plates are pale pink and its girdle is white and brown)

Underneath the shell, the chiton's body is soft. It consists largely of a muscular foot that is used for movement. To either side of the foot is the mantle cavity, which consists of channels filled with gills that water is pulled through. There is no distinct head, but a mouth is present on the front end. Inside the mouth is the radula, a tongue-like appendage that is covered in teeth. The teeth are special because they are coated in magnetite, a very hard magnetic mineral that has iron as one of its main ingredients. While the metal is used to reinforce the teeth and keep them from wearing out (in fact, the chiton Chaetopleura apiculata has the hardest teeth of any known animal), it may also be used for magnetoreception. This is when an animal can sense magnetic fields. It is possible that the magnetic teeth of chitons can sense the Earth's magnetic field and help with navigation and migration. Most chitons are herbivores or omnivores that feed on algae, bryozonans, diatoms, and other tiny rock-dwellers by scraping at rocks with their radulae. Some are carnivores that target barnacles and can even eat small crustaceans and fish. They often hunt by holding the front ends of their girdles up in the water. Should an animal mistake it for shelter, the chiton will clamp down on them. Food is forced through the esophagus by a current of mucus moved by cilia.

(image: the underside of a chiton. it is oval and orange all over. Two groves filled with brown gill filaments go down each side of the body, encircling a central foot. The mouth is visible as a small hole on one end)

When it comes to senses, chitons have a few options. Like their gastropod cousins, chitons have a chemosensory organ called the subradular organ used for smell and their feet and girdles are full of sensory nerves. They also have special organs called aesthetes. These consist of light-sensing cells that are just below the surface of the shell. The aesthetes are not true eyes, only being able to distinguish light from dark, though they can tell the difference between a shadow and the effects of clouds moving over the sun. Some species use collections of aesthetes to form simple eyes called shell eyes. Unlike the aesthetes, the shell eyes can form images, though Chitons do not have nerve structures needed to form a high resolution image. Shell eyes are distinct from those of any other animal in their structure. Most animals have eye lenses made of protein-based structures, but chiton lenses are crystalline, made of aragonite, the same material that makes up the shell of most mollusks. Each shell eye is compound. The shell eyes are almost certainly used for predator detection. Fossil chitons have been found dating back to the Cambrian period. but shell eyes have only been found in fossils from less than 10 million years old. This likely makes chitons the most recent animal group to have evolved true eyes. Chiton eyes have also been found to work both in water and air, which is tricky due to the way light travels differently through both mediums.

(image: a close-up of a chiton's shell showing the eyes. The shell is yellow and lumpy with the eyes visible as darker, almost black lumps)

The majority of chitons live in intertidal or sub-tidal areas, making them a shallow water group. A few species have been found living in much deeper water, up to 2,000 meters down. Chitons have been known to have homing behavior as they will consistently return to a safe spot after feeding. How they do this is unknown. Sensing the magnetic field of the Planet may play a role, though it is also possible that they lay down chemical trails to find their way home. Chitons are broadcast spawners, with both males and females releasing gametes into the water. Larvae can swim for a while before moving to the substrate.

(image: microscope images of a chiton larva at 4 different developmental stages. It begins as a round blob ringed with hair-like cilia. As the animal develops the cilia recede and the animal elongates, with a distinct foot becoming visible. source)

I will close by bringing up an animal I only learned about recently but has rapidly become one of my favorite weird beasts. This is Cryptochiton stelleri. Its common name is the gumboot chiton, but some people call it the wandering meatloaf, which is objectively the best name ever. It is the largest chiton, growing up to 36 cm (14 in) and 2 kg (4.4 lbs). Its girdle completely covers its shell, which does make it look more like a meatloaf. They can live up to 40 years and are the first known animals to have the mineral santabarbarite in their bodies. They live throughout the north pacific and have been used as a food source by many different cultures. There may be a lot of bad stuff in the world, but if things get too bad, just remember that we live on the same planet as an animal called the wandering meatloaf that can live for 40 years and has a tongue covered in magnetic teeth.

(image: a wandering meatloaf. It is an ovoid animal with red-orange tissue covering the body. Its shell is not visible, but the ridges where each plate overlaps can be seen through the girdle)

I FORGOT WANDER WEDNESDAY 💔

I just drew wander in some poses, plus some drag outfits he's had 😋

[thelazzyblogzz]

Happy wander Wednesday. Here’s your weekly wander slop.

[madd-draws]

their relationship is everything to me

(tag however you like! wander/sylvia shippers please interact please I'm BEGGING)

Wander

So...i have nothing do do for Wander Wednesday

This is only best i can do...

Happy Wander Wednesday, Wanderers!
