Writing down interesting fish facts for me to use in my yuri puzzle game fishy facts. When I say "fish" I mean anything you might see in an aquarium, flora or fauna or etc.
Fish facts I already know:
- Whale is big.
- Seahorse mpreg is a thing.
- Clownfish change gender
- Horseshoe crabs have blue blood and this blood has medical applications of some sort.
- Mariana Trench is the deepest point on Earth.
- Carcinisation, the tendency to become crab.
- "Fish" as it is used in English is not the same thing as what a fish is in the animal kingdom. There are a lot of organisms that are not related which we collectively call fish.

New facts:
- A caustic is the pattern of light that has been refracted or focused together, such as by the turbulence of the surface of water. Maybe Cuttlefish know how to blend in with caustics too? https://www.sciencedirect.com/science/article/pii/S096098222400767X
- This link was further cemented by Kreidl in 1893,
who put iron filings into the statocysts of
Palaemonetes shrimp to act as statoliths
and controlled the motion of the shrimp using a
magnet (Kreidl 1893; Fraser and Takahata 2002) https://link.springer.com/rwe/10.1007/978-3-031-94229-7_192-1

- No swim bladder, but they have a jelly-like layer of flesh that is 90% water. They are neutrally bouyant throughout their entire diving range
- Can be infested by around 50 different kinds of parasites (at the same time? unclear)
- Sunfish like to lay on the surface of the ocean to sunbathe to warm up after cold dives and let birds and fish eat the parasites from their body
- Sometimes predators take a bite out of the sunfish and decide that they would rather starve.
- They have many eggs for a single mating session (300 million)
- They can eat thousands of jellyfish in a single day
- Their brains are extremely small in proportion to their body (of all animals maybe? unsure)
- They grow extremely big extremely fast -- 25kg to 400kg in a matter of months
- They are so successful, that they exist all around the world
- ⭐Sunfish so big it had to be airlifted out by helicopter from a holding pool. https://www.sfgate.com/news/article/Sunfish-Airlifted-to-Freedom-Monterey-Bay-2979690.php
Dolphins use Pufferfish to get high, maybe? Only documented case is from 2014 BBC documentary Dolphins - Spy in the Pod Episode 2 "Pass the Puffer" that portrays it as the dolphins getting high, but the dolphin behavior could also be explained as being normal behavior.- Probably not actually true.
- But it could also be just another day in the
dolphin pod — ignore the spiky lethal fish, and the
behavior isn’t out of the ordinary. "We’ve observed
dolphins pass fish around in normal play behavior,"
Diana
Reiss, a dolphin cognition researcher at Hunter
College, told NBC News. https://www.nbcnews.com/science/science-news/dolphins-getting-high-fish-toxin-or-just-load-puff-n3691

to trick the sea anemone into not eating it. https://youtu.be/vNhORnwcQcU?t=57
- This happens in the opening scene of Finding Nemo too
- Hermit crabs also like to use sea anemones as mobile defensive structures on their shell
- All clownfish are born male, the largest clownfish in the group becomes female. https://www.youtube.com/watch?v=lgUFkM34R7U
- Sea Anemones can move to avoid predation
- Crabs can use Sea Anemones for collecting food (by stealing what the Sea Anemone catches), for defense (by using the toxins of the Sea Anemone to ward of predators), and will also tear Sea Anemones apart so they can use them in both hands. https://www.youtube.com/watch?v=g3awDijFtYQ

- Cuttlefish only live for 1-2 years https://youtu.be/EF8C4v7JIbA?t=2241
