Saw a pair of male Atlantic Sand and Red-Jointed(Minuca minax) Fiddler crabs fighting at the marsh! Saw lots of M. minax aggression, which is high stakes for the other crabs; M. minax has developed the ability to eat their peacefulish cousins!

A zoom shot of a muddy marsh with the base of cordgrass visible. A pair of male fiddler crabs interlocks claws in the middle of the image. The closer fiddler crab has a white mottled back with a light colored arm and claw. The further, larger fiddler crab has a brown back and red/brown arm and claw.

okay I'm bored have a fiddler crab on the house
A fiddler crab stands in the left half of the image among wet beige sand; zoomed in shot. It has a bright purple back, rimmed by silver, with light brown body.

Finally getting around to posting some of the crab shots from last week! Here is Uca/Leptuca pugilator, the Atlantic Sand Fiddler Crab!! I love these lil dudes SO MUCH! At Cedar Point Tideland Trail, NC!

A fiddler crab stands in the center of the image; it faces the camera, holding its claws in front of its body. It has one huge claw and one tiny one, both being a pearly white color.

Went down to coast (Swansboro/Outer Banks) and got a TON of crab photos, but I think I'm gonna start it off with a Carolina Saddlebags (Tramea carolina)! Shiny lil bud

#NC #nature #insects #wildlife #wildlifephotography #dragonflies
A orange dragonfly perched on a twig in the center of the image. It is facing away from the camera, its wings spread wide. The forward set of wings is fully transparent, though glinting colorfully in the light. The back set of wings is about one third opaque with patterned brown coloration, and the rest is transparent. The body of the dragonfly is orange.

Today I was at the coast photographing crabs and got out of a cyclist's way (i was sitting on a lil bridge thing) and they said "Have a good walk!" and then I said "You too!"

anyway here's the email I sent to jim bankoff last week. i'm still heartbroken. I have been insanely, destructively angry for weeks, and I think I will be for a long time.

he screm

(Green anole, sometimes called the Carolina Chameleon!, #NC) #lizards #reptiles #wildlife
A telelphoto shot of a Green Anole perched on the edge of an old grey wooden railing, which has cracked slightly. The anole is in profile, its mouth open very wide, and its throat crest extended (though mostly hidden behind the railing). The anole is greenish-brown, mid-transition between its two color states. Photo by me.

I was today years old when I learned that the Magic Schoolbus was an NSF-funded project.
Image of the TV series The Magic School Bus accompanied by the following text: Airing on PBS in the mid-1990s, this NSF-funded animated TV show follows Ms. Frizzle and her class as they set off on field trips out of this world, including careening across the solar system, traveling through the human body or visiting the late Cretaceous period.

This is me and my dog whenever he insists there is space on the couch. The one on the left was visibly teeter-tottering 😆 From Huntley Meadows, #Virginia.

Four turtles on a dried out log in murky brown water. One is out of focus in the foreground, one is out of focus in the background. The two in focus are jostling for the same spot on the log, with one hanging on by just two limbs.

An extremely vocal Osprey this past month down at Cedar Point Tideland Trail in the #NC #outerbanks! There's usually a full family down there but this buddy was a ways away from their nest, maybe moving out?

A black and white bird of prey perched on a branch, image is looking up from below as it looks to the left. The beak is sharply curved, and there is a black stripe on the otherwise white head going through the yellow eyes.

Mountain Laurel in bloom last May at Poor Mountain Trail, #VA. Took some proper one-lane mountain roads to get there!

Despite knowing, intellectually, that waking early enough to catch the birds' dawn chorus will be amazing, it still manages to breathe new life into me every time I remember to.

Coming out of hibernation to share this; Needlerush at the salt marsh. Taken on Hoop Pole Nature Trail on the #outerbanks a while back. When you look into it in person, the visual noise kills all sense of depth, it's really quite mesmerizing.

Long, thin, pointed tan-colored grass of varying shades stretches from the foreground to the background, where a sliver of ocean can be seen.

Dropped my phone 3 inches today and now the right 1/4 of the screen is a light blue rectangle so if y'all could please stick to haiku-length lines that would be al peak.

I keep clicking on pls profiles to see more of their stuff, forgetting I have done so, and later wondering why what I think is my home feed has so much of one person's stuff

OH also morning science thingyy!!!! Aye-ayes, a type of freaky lil lemur dude (a scientific term), do echolocation, but in wood! They tap on a tree and listen closely and can tell from how the sound waves interact if there's an insect bored in that piece of the tree; it's called percussive foraging!

It's #Oldworkwednesday, so here's a shot I took probably in '21, '20, back before I switched from my PixPro to a DSLR, and when I was still very much learning! This was taken at Cedar Point Tideland Trail, NC.

Love when nature presents comical little tableaus like this.

A shot of two fiddler crabs on a rough, wet sandy ground. One is sitting inside a hole filled with water, sticking its eyes out, facing the other, who is standing next to the hole, facing away from the camera.

Science fact of the morning time! Marsh periwinkles (a kind of snail) DO LIKE LEGIT FARMING BEHAVIOR. they eat fungus, but most of the time you see them on salt grass blades, where there is none. So they scrape open the grass, "drop" fungal spores into the wound, AND EAT THE FUNGUS THAT GROWS IN IT

Fell asleep on the couch and woke up this morning to find my dog's face ~4 inches from mine, illuminated only by the TV light. I made a very brave noise. /j

Sciencey fact of the afternoon: fiddler crabs can see the polarization of light, making harder for birds to blend in with the sky (since light from the sky has a different polarization than light bounced off the ground)! They do this by having compound eye segments polarized in alternate directions!

Fun sciencey fact of the day: ring tailed lemurs have spurs on their wrists, which then have many tiny tubes leading from the spur surface to the skin below. The skin excretes oils and stuff, which moves through those tubes, and then the lemur rubs the spur on its tail to get proper stinky.

This #cute harbor seal is a pinniped (group w/ #seals, sea lions, walruses, etc) that lives in northern ocean waters. They've tons of cold-water adaptations, including SPECIALLY HEATED WHISKERS. Whiskers need to be warm to work; here's how they do it: (thread) (1/3)
#marinelife #wildlife #funfacts
Harbor seal poking its head out of the water, turning its head to face the camera as its body extends out of frame to the right. Its eyes are round and irises large, and its nostrils are flared. It has whiskers on its nose and just above its eyes; the whiskers are long and white.

Hi all! Just joining #bluesky and LOVING IT!!! I'm a student and amateur photographer, and hope to post cool #science stuffs here!! I have a special interest in fiddler crabs and salt marshes!
This #bird is a Red-and-Green Macaw I saw this weekend, who nanoscopically manipulate light! (thread)
