yes that’s the actual name you read it right. they’re mean little motherfuckers who live off the california coast and I believe they deserve a Best Fish Award because:
I love them so much because they’re about as sharp as a baseball and their anatomy is ridiculous to the point of them literally being classified as plankton for years because they just sort of get blown around by the ocean and look confused, but because they lay more eggs than ANY OTHER VERTEBRATE IN EXISTENCE, evolution can’t stop them
Why is no big predator coming and gnawing on them?
Their biggest defense is that they’re massive and have super tough skin, but they do get hunted by sharks or sea lions sometimes and they just sort of float there like ‘oh bother’ as it happens
Even funnier, because they eat nothing but jellyfish they’re really low in nutritional value anyway, so they basically survive by being not worth eating because they’re like a big floating rice cracker wrapped in leather.
So basically the only reason natural selection hasn’t taken care if them is because they are the most useless fish
yes, they’ve perfected uselessness to the point of being unstoppable
a true inspiration
I bet they are secretly thinking some big fish thoughts.

It doesn’t take long for tropical zebrafish to get hooked on hydrocodone. Within a week, they will risk their lives thousands of times per hour to get a dose of the opioid, shows the first study that let the fish themselves choose when to take a hit. To train them, researchers released 1.5 milligrams of hydrocodone per liter of water every time they swam over a shallow platform. The drug quickly filtered out of the tank, so they had to keep going back if they wanted to maintain their high. After just 5 days, the trained fish were visiting the opioid-delivering platform almost 2000 times every 50 minutes, the team reports online today in Behavioral Brain Research. When no drug was present, they visited the platform only about 200 times.
Because zebrafish and humans share the same opioid receptor in their brains, as well as neurotransmitters such as dopamine and serotonin that signal pleasure and reward, the team hopes to use them to screen for new treatments for opioid addiction.
