There are four types of fish scales!
Cycloid scales are thin, overlap, and flexible. They're found on primitive teleosts (like minnows and carp).
Ctenoid scales have small, backwards pointed scales (known as cterns) make the fish more hydrodynamic and faster. They're found on Advanced Ctenoids (like perch and sunfish).
Ganoid scales are thick, diamond-shaped, and mostly non-overlapping. They're found on Chondrostei (like sturgeons and paddlefish).
Placoid scales are spikey and tooth-like with nerves. These are found on Chondrichthyes (like sharks and rays).

ADHD pro tip: Use psychological warfare on yourself.
For example, in order to do long tasks, like folding laundry, I put on the Mario Hat:
The main feature of the Mario hat is that my headset does not fit over it, so when The Bees™ try to put me back in front of the screen, the headset issue forces me to remember why I put the Mario hat on, and back to the task I go
As a bonus, the Mario hat is also a very clear indicator to my housemates that business is getting done, and they have learned not to distract me when I'm wearing the "goofy-ass cosplay hat"
It's not stupid if it works.
Having ADHD is a lot like being only able to travel with a hot air balloon. When the wind is right and the weather conditions are ideal, you can effortlessly go wherever you could possibly want, with almost no energy seemingly spent. And when the weather just Will Not Do That, there's nothing you can really do about it. Advice from people telling you to just fucking Grow Up And Learn To Steer don't believe you when you say you've got no steering wheel. Your explanations of navigating different wind directions at different altitudes make no sense to them.
So you just gotta accept that some days the wind goes your way, some days it won't. You can either exhaust yourself fighting the wind, accept that you're going nowhere at all today, or that the direction you are currently going is not the way you planned to go. Why am I in Uruguay.
generally speaking when it comes to mental and physical health, if you're asked "do you struggle with this" and your answer is "no, Because I Have A System," then your answer is actually yes
collection of useful things tumblr has taught me:
even if you can't fall asleep, laying down with your eyes closed will still rest your body
you don't have to brush your teeth standing up
you don't have to do any chore standing up, from dishes to showering
you don't have to shower with the lights on
if you can't brush your teeth, flossing and a tongue scraper gets rid of plaque and bad breath
if you can't do that, mouthwash kills a lot of bacteria
eating "unhealthy" food is better than eating no food
you can make the same meal everyday for however long you still want it
some pills come in syrups or chewables if you can't swallow them
kids nutritional shakes can be a quick way to get fuel if you can't eat/don't have time
if walking hurts/exhausts you on a regular basis, canes and rollers are for you, no matter how young you are
we have free will—if doing something "out of the ordinary" makes life easier for you, do it
a piece of advice my dad gave me and I’ve never forgotten is, “if you won’t worry about it in 4 months, don’t worry about it now.” saved me countless times, it’s a philosophy to adopt and help improve your life. Failed a test? ask yourself if you’ll think about this still in 4 months? Made a fool of yourself in public? I doubt even the people who saw it will remember it past today. Know you could have done better? Ran further? don’t beat yourself up over it, you can do better tomorrow. Don’t overthink things, a lot of negatives matter less than you think they do.
Reblog if your blog is boopable-safe so you can get all the (probably new) achievements. I don’t care about notes I just want boops
Wait, so you said that you can learn to trust others by building friendships, but how does one go about doing that? Wouldn't someone I don't know be creeped out or annoyed if I suddenly walked up and started talking to them?
Friendships are built of repeated low-stakes interactions and returned bids for attention with slowly increasing intimacy over time.
It takes a long time to make friends as an adult. People will probably think you're weird if you just walk up and start talking to them as though you are already their friend (people think it's weird when I do this, I try not to do this) but people won't think it's weird if you're someone they've seen a few times who says "hey" and then gradually has more conversations (consisting of more words) with them.
I cheat at forming adult friendships by joining groups where people meet regularly. If you're part of a radio club that meets once a week and you just join up to talk about radios, eventually those will be your radio friends.
If there's a hiking meetup near you and you go regularly, you will eventually have hiking friends.
Deeper friendships are formed with people from those kinds of groups when you do things with them outside of the context of the original interaction; if you go camping with your radio friend, that person is probably more friend than acquaintance. If you go to the movies with a hiking friend who likes the same horror movies as you do, that is deepening the friendship.
In, like 2011 Large Bastard decided he wanted more friends to do stuff with so he started a local radio meetup. These people started as strangers who shared an interest. Now they are people who give each other rides after surgery and help each other move and have started businesses together and have gone on many radio-based camping trips and have worked on each other's cars.
Finding a meetup or starting a meetup is genuinely the cheat-code for making friends.
This is also how making friendships at schools works - you're around a group of people very regularly and eventually you get to know them better and you start figuring out who you get along with and you start spending more time with those people.
If you want to do this in the most fast and dramatic way possible, join a band.
In 2020 I wrote something of a primer on how to turn low-stakes interactions with neighbors and acquaintances into more meaningful relationships; check the notes of this post over the next couple days, I'll dig up the link and share it in a reblog.
you can say sex and kill its fine
If you don't have a profile picture people will assume you're a bot
theres barely an algorithm, if you want to see cool shit reblog things instead of just liking them
follower count doesnt matter
tumblr fame gets you one thing and it is Yelled At
no one knows what the fuck the nsfw policy is
block anyone that annoys you even a little bit
And most importantly:
post cringe
I’m a young-adult woman with the hopes of becoming a well-known writer. I’m a dreamer, a music lover and a chaotic human being, curious about what the future will bring but without any idea of what to do with it. As for this tumblr, we’ll see. I will make an attempt to make an interesting place but for now I still have to figure out what to do with it.
