Women's Not So Distant History

This #WomensHistoryMonth, let's not forget how many of our rights were only won in recent decades, and weren’t acquired by asking nicely and waiting. We need to fight for our rights. Here's are a few examples:

📍 Before 1974's Fair Credit Opportunity Act made it illegal for financial institutions to discriminate against applicants' gender, banks could refuse women a credit card. Women won the right to open a bank account in the 1960s, but many banks still refused without a husband’s signature. This allowed men to continue to have control over women’s bank accounts. Unmarried women were often refused service by financial institutions entirely.

📍 Before 1977, sexual harassment was not considered a legal offense. That changed when a woman brought her boss to court after she refused his sexual advances and was fired. The court stated that her termination violated the 1974 Civil Rights Act, which made employment discrimination illegal.⚖️

📍 In 1969, California became the first state to pass legislation to allow no-fault divorce. Before then, divorce could only be obtained if a woman could prove that her husband had committed serious faults such as adultery. 💍By 1977, nine states had adopted no-fault divorce laws, and by late 1983, every state had but two. The last, New York, adopted a law in 2010.

📍In 1967, Kathrine Switzer, entered the Boston Marathon under the name "K.V. Switzer." At the time, the Amateur Athletics Union didn't allow women. Once discovered, staff tried to remove Switzer from the race, but she finished. AAU did not formally accept women until fall 1971.

📍 In 1972, Lillian Garland, a receptionist at a California bank, went on unpaid leave to have a baby and when she returned, her position was filled. Her lawsuit led to 1978's Pregnancy Discrimination Act, which found that discriminating against pregnant people is unlawful

📍 It wasn’t until 2016 that gay marriage was legal in all 50 states. Previously, laws varied by state, and while many states allowed for civil unions for same-sex couples, it created a separate but equal standard. In 2008, California was the first state to achieve marriage equality, only to reverse that right following a ballot initiative later that year.

📍In 2018, Utah and Idaho were the last two states that lacked clear legislation protecting chest or breast feeding parents from obscenity laws. At the time, an Idaho congressman complained women would, "whip it out and do it anywhere,"

📍 In 1973, the Supreme Court affirmed the right to safe legal abortion in Roe v. Wade. At the time of the decision, nearly all states outlawed abortion with few exceptions. In 1965, illegal abortions made up one-sixth of all pregnancy- and childbirth-related deaths. Unfortunately after years of abortion restrictions and bans, the Supreme Court overturned Roe in 2022. Since then, 14 states have fully banned care, and another 7 severely restrict it – leaving most of the south and midwest without access.

📍 Before 1973, women were not able to serve on a jury in all 50 states. However, this varied by state: Utah was the first state to allow women to serve jury duty in 1898. Though, by 1927, only 19 states allowed women to serve jury duty. The Civil Rights Act of 1957 gave women the right to serve on federal juries, though it wasn't until 1973 that all 50 states passed similar legislation

📍 Before 1988, women were unable to get a business loan on their own. The Women's Business Ownership Act of 1988 allowed women to get loans without a male co-signer and removed other barriers to women in business. The number of women-owned businesses increased by 31 times in the last four decades.

📍 Before 1965, married women had no right to birth control. In Griswold v. Connecticut (1965), the Supreme Court ruled that banning the use of contraceptives violated the right to marital privacy.

📍 Before 1967, interracial couples didn’t have the right to marry. In Loving v. Virginia, the Supreme Court found that anti-miscegenation laws were unconstitutional. In 2000, Alabama was the last State to remove its anti-miscegenation laws from the books.

📍 Before 1972, unmarried women didn’t have the right to birth control. While married couples gained the right in 1967, it wasn’t until Eisenstadt v. Baird seven years later, that the Supreme Court affirmed the right to contraception for unmarried people.

📍 In 1974, the last “Ugly Laws” were repealed in Chicago. “Ugly Laws” allowed the police to arrest and jail people with visible disabilities for being seen in public. People charged with ugly laws were either charged a fine or held in jail. ‘Ugly Laws’ were a part of the late 19th century Victorian Era poor laws.

📍 In 1976, Hawaii was the last state to lift requirements that a woman take her husband’s last name. If a woman didn’t take her husband’s last name, employers could refuse to issue her payroll and she could be barred from voting.

📍 It wasn’t until 1993 that marital assault became a crime in all 50 states. Historically, intercourse within marriage was regarded as a “right” of spouses. Before 1974, in all fifty U.S. states, men had legal immunity for assaults their wives. Oklahoma and North Carolina were the last to change the law in 1993.

📍 In 1990, the Americans with Disability Act (ADA) – most comprehensive disability rights legislation in U.S. history – was passed. The ADA protected disabled people from employment discrimination. Previously, an employer could refuse to hire someone just because of their disability.

📍 Before 1993, women weren’t allowed to wear pants on the Senate floor. That changed when Sen. Moseley Braun (D-IL), & Sen. Barbara Mikulski (D-MD) wore trousers - shocking the male-dominated Senate. Their fashion statement ultimately led to the dress code being clarified to allow women to wear pants.

📍 Emergency contraception (Plan B) wasn't approved by the FDA until 1998. While many can get emergency contraception at their local drugstore, back then it required a prescription. In 2013, the FDA removed age limits & allowed retailers to stock it directly on the shelf (although many don’t).

📍 In Lawrence v. Texas (2003), the Supreme Court ruled that anti-cohabitation laws were unconstitutional. Sometimes referred to as the ‘'Living in Sin' statute, anti-cohabitation laws criminalize living with a partner if the couple is unmarried. Today, Mississippi still has laws on its books against cohabitation.

the ribbon seals most defining feature, their stripes, take 4 years to develop!

here is a short timeline of their development 🦭

adorable white coat ribbon seal pups. this baby fur is called lanugo.

after around 1 month pups will start shedding their baby fur to reveal a grey and silver coat

young seals with their grey and silver coat

then, the juvenile seals with start to develop their stripes over the next 3 years. they grow stronger with each moult, females can reach sexual maturity before they have fully developed stripes. this mothers stripes aren’t fully there yet.

once they’re 4 years old a ribbon seals stripes will have fully developed.

male and female are easy to tell apart by their coat colour, the males will have bold black and white stripes

whereas the females have more brown/beige/silver stripes

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.

A reminder to hypnosis subjects and those interested in hypnosis

I've been thinking about this for a while now, especially because I had to explain it to a subject who was new to being hypnotized recently. It's something not often acknowledged in the hypnosis community, at least from what I've seen.

As much as hypnosis is often portrayed as mind control, and as much as I often like to lean into that fantasy that I control my subjects' will and body, you the subject are in control at the end of the day. You are lending control to the hypnotist, and how much you lend is up to you! Many people enjoy the idea of the hypnotist having complete control over them, but it's just that: an idea, a fantasy.

Now, that isn't to say you aren't easier to convince while hypnotized. I like to think about it like being in a really good mood - you're happy to do things you normally wouldn't do, but you're still you, and you won't do anything that you really wouldn't want to do no matter what. Because of that, I always recommend being hypnotized only by those you trust, someone who cares about your well-being. But that means if a hypnotist is making you uncomfortable for whatever reason, you have the power to reject what they're telling you, no matter what they say. They're called "suggestions" for a reason, and hypnotists are more of a guide than someone who controls your every whim.

You might also find that when you're hypnotized, you're still "aware" of what's going on, and it might feel like you can stop it at any time. And that's okay! That usually is a sign that you're being hypnotized, not the other way around. You are in control and you can stop at any time, but the fun of hypnosis is that you won't want to stop listening to the hypnotist's words, their suggestions will feel like there's no harm in following them (provided it's something you're okay with). You're in control, but you're choosing to let go and let the hypnotist guide you into doing things that you might not normally do and you might enjoy.

As I said earlier, I like leaning into the fantasy of controlling my subjects almost completely, but I make sure they're okay with that sort of thing before I ever hypnotize them (and a lot of the time, people are). We talk about our limits and boundaries, what we want out of a session, and I do my best to make sure my subjects feel comfortable and safe around me. Ideally, anyone trying to hypnotize you will do the same! This allows those who really like the idea of handing control to me to do so in a safe space.

Hopefully this helps someone out there, and I hope y'all have a good day. ^w^
