& related institutions.

I have some stories of my own to tell, and I want to hear about your experiences in these places, too!

About me: I just took early retirement after working for more than 25 years as the web designer, editor, and photographer for a natural history museum. I have a BA in anthropology and a master's in museum studies. I had graduate assistantships in the exhibits, entomology, and geology/paleontology departments of the university museum where I was working towards my degree. Before that, I worked as a sort of general assistant in a small science museum. Earlier still, I volunteered with the exhibits team at a science & nature center that also had a small zoo.

My parents were both scientists - mom was a high school biology teacher (and a botanist by training) and dad was a physicist. They both loved to travel, and we did a lot of that when I was a kid. We took a few cross-country road trips, and also took trips to Canada, France, the UK and Switzerland. I've done limited travel on my own to Germany and Denmark. I've been to museums and similar places on most of these trips. I plan to share my thoughts on those experiences here.

Please join me in exploring the world of museums!

I just learned that Carl Sagan suffered from chronic pain his entire adult life, starting in college. He had achalasia.

How did I not know this? I'm gonna cry.

As someone who developed chronic pain while in college, who wants to be a science communicator but regularly doubts their ability to do so.... This is such a validating thing for me to learn. Maybe I can do this despite my pain and disabilities. Maybe I'm not foolhardy for pursuing an advanced degree so that I can interpret science for the public. I have no desire to be the public face of Planetary Science the way he was but... Maybe I can be someone.

Prompt 271

“Grandmother is visiting,” Damian suddenly said with no warning and with his usual not-quite demanding tone. 

“Who?” Tim wasn’t the only one to startle, seeing as Bruce had practically froze, a downturn to his lips in a silent show of confusion. 

Damian scowled. “Are you deaf Drake? Grandmother is coming to Gotham to, quote, make sure I am being properly cared for.” None of them had known that Ras was with anyone actually. At least Tim was pretty sure that would have been in the files. 

“Oh?” Dick didn’t quite crouch to Damian’s height but it was a near thing. “She-” “He,” Damian corrected, interrupting him. They all exchanged a glance before Dick continued. 

“Is he coming to the Manor or…” 

Damian scoffed again, a tiny bit of a flush against his face. “No, Grandmother will most likely be staying with Akhi-”

Now wait one moment-

“YOU HAVE ANOTHER BROTHER?!”

Wet Beast Wednesday: moray eels

This week on Wet Beast Wednesday I'll be going over something amazing, a fish with a sense of morality. You see, the moral eel is known for, what... I think I'm reading this wrong. Oh, MoRAY eel, not moral. Well this is awkward. Hang tight, I need to go redo my research.

(Image: a green moray (Gymnothorax funebris) swimming outside of its burry, with its whole body visible from the side. It is a long, slender fish that looks a bit like a snake. A long fin starts just below the head and continues down the length of the body. The body is arranged in a wave pattern. It has a pointed snout and small eyes. Its body is a yellow-green color. In the background is the sandy seafloor, dotted with various sponges and corals. End ID)

Moray eels are true eels, meaning they are in the order Anguiliformes. Yeah, I did wolf eels, electric eels, and lamprey eels before I got around to actual eels. There are over 200 known species of moray eel in 15 genera. Like other eels, they are elongated bony fish with extra vertebrae and reduced fins. Moray eels have fewer fins than most eel species, only having a dorsal, anal and tail fin that merge together and run down the back of most of the body and underneath portion of it. They achieve motion by undulating this long fin and sometimes undulating the rest of the body as well. Moray eels aren't the fastest of fish, but they can swim backwards, something almost no fish can. The head has a long snout with wide jaws. Most species have long fangs used to grab onto prey, but a few species are adapted to eat hard-shelled prey and have molar-like teeth to crush through shells instead. Probably the coolest feature of morays are the pharyngeal jaws. This is a second set of jaws located in the back of the mouth. When the eel bites onto prey, the jaws can be shot forward to grab the food and help pull it into the throat. While lots of fish have pharyngeal jaws, morays are the only ones who can extend their pharyngeal jaws forward and use them to grab prey. Morays have smooth, scaleless skin that is often patterned to provide camouflage. The skin is coated in mucus that provides protection from damage and infection. In some species, the mucus can be used to glue sand together to help reinforce burrows. Morays lack lateral lines, a system of organs found in most fish that senses changes in water movement. Their sense of smell is their primary sense. The size of morays varies between species. The smallest species is the dwarf moray eel (Gymnothorax melatremus) which reaches 26 cm (10 in) long. The largest species by mass is the giant moray eel (Gymnothorax javanicus) which can reach 3 meters (10 ft) and 30 kg (66 lbs) while the longest species is the slender giant moray (Strophidon sathete), the longest known specimen of which measured in at 3.94 m (12.9 ft).

Moray eels are found throughout the Atlantic, Pacific, and Indian oceans. Different species are found in different temperatures and depths, though most species live in relatively shallow, warm water. Several species can live in brackish water and a few will swim upriver and live for a time in fresh water, though there do not appear to be any species that live their entire lives in fresh water. Morays are ambush predators who rely on the element of surprise. They live in small, tight places such as holes in coral, gaps between rocks, or sandy burrows. When prey passes, the eel can lunge out and grab it. Unlike most fish, the eel cannot use suction feeding due to the shapes of their mouths. They have to rely on lunging froward and catching prey with their mouths. Their mouths are adapted in shape to push water to the sides. This reduces water resistance and avoids creating a wave that could push prey away from the eel. If an eel catches prey that cannot be swallowed whole, it will tie itself in a knot while biting on to the food. By pulling its head through the loop, the eel can rip the food into bite-sized pieces. Spending most of their times in burrows also provides protection from predators, especially in juveniles or smaller species. At night, the eels will come out of their burrows to hunt sleeping prey while the larger predators are asleep. Giant morays have also been seen engaging in interspecies cooperative hunting with roving coral groupers (Plectropomus pessuliferus). The eels can fit into small crevices the groupers can't to flush prey into the grouper's path while catching their own. Morays are mostly solitary species and many can be territorial. They are known to be shy and will retreat into their burrows if they feel threatened. They are also curious and many species are quite intelligent.

(Image: a male ribbon eel (Rhinomuraena quaesita) on a coral reef. It is a very long and slender eel with its body curved in many waves. It is brightly colored, with a blue-purple body, yellow fin and face, and a long black and white stripe running down the back half of the body. On the nostrils are two feather-like structures. End ID)

Morays reproductive strategies are poorly known and differ based on species. While many species seem to have no set mating season and will reproduce whenever they can, others will mate at the same time every year. Some species seem to have dedicated spots to lay their eggs and a few are believed to be anadromous, meaning they travel from the sea to fresh water to spawn. Meanwhile, some of the species that spend a lot of time in fresh water are catadromous, meaning they return to sea to mate. Females will lay their eggs and the male fertilize them. After this, they depart, providing no parental care. As with all true eels, moray eels begin life as leptocephalus larvae. This type of fish larvae is notable for its resemblance to a simple, transparent leaf with a head on one end. These larvae are unique and poorly understood, despite being the larval stage of a lot of different species of fish. They are unusually well developed for larvae, capable of active swimming and generally living life. In fact, some particularly large leptocephalus larvae were initially mistaken for adult fish. They feed mostly on bits of drifting organic material called marine snow and can remain in the larval stage for up to 3 years, with those in colder conditions usually taking longer to metamorphose. All leptocephalus larvae start out with no sex organs, then develop female organs, then develop male ones, becoming simultaneous hermaphrodites. They will ultimately become eith male or female and it is likely that environmental factors are the main determining factor. During metamorphosis into a juvenile, the leptocephalus can reduce in size by up to 90%, resulting in the juvenile being smaller than the larva. The process of maturation is poorly understood, but it seems that most morays will be sexually mature by three years of age.

(Image: multiple photos of a particularly large leptocephalus larva (not sure what species). It is a translucent organis, wth a body shaped like a very long leaf, narrow at both ends. In the frint is a very tiny head. End ID)

Morays are shy and generally avoid humans. Though some cultures have hunted them for food, they are often not considered a particularly good food source. Many species have high levels of chemicals called ciguatoxins in their bodies, which can lead to a condition called ciguatera fish poisoning if eaten. The largest threat to morays is habitat loss. This is especially true for the many species that live in coral reefs, which are in increasing danger due to global warming. Attacks on humans are rare and usually happen as a response to a human sticking their hand in the eel's burrow. Some of the large species could cause significant damage with a bite. Some species, usually the smaller ones, are found in the aquarium trade, thought they are not good pets for beginners as even the smallest morays are still large for aquarium fish and have some specific requirements. The curiosity many morays have has led to some becoming familiar with and even friendly to humans, often the result of feeding them. They can recognize individual humans and remember them over the course of years. Aquarium employees sometimes report that the eels will come to nuzzle and play with them and have personalities like dogs. Marine biologists and professional SCUBA divers Ron and Valorie Taylor befriended a pair of eels they named Harry and Fang at the Great Barrier Reef who would remember them and come out to visit them year after year.

To all the people who think aspec people aren't LGBTQIA+ because we aren't "discriminated against enough", here's a lovely list of reasons why you need to educate yourself:

- We suffer from dehumanisation, people actively devaluing or even erasing our humanity because of our identities (The voidpunk community is heavily supported by aspec people because of this)

- We suffer from self hatred due to feeling as if and being told we are broken, that no one can be happy unless they're in a romantic/sexual relationship, because of allonormativity and amatonormativity that actively damages our mental health

- Amatonormativity shapes laws that put us at an active disadvantage, such as giving married people financial and legal benefits

- Aspec people have been victims of conversion therapy, correctional rape, a lower quality of life, and other effects of being a marginalised and oppressed group

- We suffer from our identities being pathologised and deal with medical stigma because of this, causing many of us to feel unwelcome in and even avoid health care settings

- We suffer from our identities being erased, which can range from people completely denying our existence and people equating it to celibacy, to an almost complete absence of aspec representation in the media (It's been getting better lately, especially for alloaces and aroaces, but I have yet to ever see a canon aroallo character, and representation for those on the spectrum rather than in the extremes is often ignored)

- YOU are creating a hateful, exclusionary space in a community meant to be about inclusion. The same thing that happens to us happens to bisexual people, to polyamorous people, and other identities that are "disputed." In a community meant to be about rejecting the norm, YOU are shoving us out because we don't fit the norm of being LGBTQIA+. Because we're not enough like you.

These are only a few examples of aphobia that people like me deal with. Discrimination and oppression against aspec people stretches far beyond this.

But even if it didn't, it is disrespectful and harmful to everyone involved to gatekeep membership in the community based on oppression and discrimination.

We aren't LGBTQIA+ because we experience oppression. We are LGBTQIA+ because our existence alone goes against heteronormativity and other societal norms forced upon us.

i had a friend who was raped as a teenager and had a really strict mum who did not let her go out so she was really lonely. when she turned 18 she started going clubbing and since we live in a city with a big fetish scene, she started going to the kinky venue. since she was young, naive and very pretty, she was immediately roped in by older men who did bondage shootings with her and everything. she started working in the club. to me, she was clearly groomed, but she works in a fetish shop now and is fully immersed in the scene

i have a friend who answered a job ad for a secretary when she was abroad and she and her friend ran out of money but when they arrived there it was a brothel. they both prostituted themselves for several months. they were only 18. she still talks highly of that brothel, how clean and safe it was, and wants prostitution to be legal

i read the gut wrenching biography of a thai woman who ran away from home, whose parents refused her education and treated her brother very preferably while openly hating her, and entered prostitution in sex tourist destination pattaya at only 13. she was paid by men in their 50s first for her virginity, then to piss on her. she exited at 19 and developed psychosis. she defends sex buyers, hates feminists and wants prostitution to be legal

do you see where im going with this? brainwashing is real. despite the obvious facts, the grooming, the system that pushed and pulled them, the men taking advantage of them; they defend it. so yeah, we shouldnt dismiss firsthand testimony and personal experience, but always take it with a grain of salt, always contextualise, always see it as one part of a bigger picture. liberals dont do that and have duped too many people into not doing it either. „if thats her choice its none of our business“ fuck you!

Fish of the Day

Today's fish of the day is the Alabama Cavefish!

The Alabama Cavefish, scientific name Speoplatyrhinus poulsoni, is known for being one of the rarest troglobitic fish species in North America. Discovered in 1967, by the time the alabama cavefish was scientifically described in 1974, there were only about 100 fish left. On any visit to the cave, only about 10 fish have ever been seen, but they are consistently different fish, so the estimated number is a little under 100, making them critically endangered. This also makes them a possibility for the rarest cavefish in North America!

Despite the large waterways connecting caves in Key Cave National park to several other cave systems, the Alabama cavefish has restricted itself to only one cave for reasons we don't understand. A search of over 120 caves in the surrounding area revealed no populations or signs of populations. With a range consisting only of Key cave in Lauderdale county, Alabama; these fish are constantly faced by the threat of extinction, and most of their worries are based on the limited home range, and waters entering the cave. Any water with chemicals, especially fertilizers and other agricultural runoff are a large concern. That along with competition from more aggressive cavefish, and predation from nearby crawfish. Due to their living situation and delicate population, much is unknown about these fish. But, let us go over what we do know!

The diet of the Alabama cavefish consists mostly of invertebrates found in the caves: copepods, isopods, smaller cavefish, spiders, beetles, and anything else it can find that will fit in its mouth. They grow up to a size of 2-3 inches in length. They have no eyes or pigment, and hunt solely based off of sensory protrusions that dot the head and sides, a trait evolved to handle the almost complete darkness. These fish have no breeding season, and instead breed based off of the environmental signal: when the caves flood in the winter and spring. Insufficient flooding can lead to years where no breeding or spawning occurs, and when it does females carry few eggs, and even fewer eggs hatch. Their lifespans, based off of the lifespan of Northern cavefish, are an estimated 5-10 years.
