I got my @dftbarecords.bsky.social @hankgreen.bsky.social "We never left the water" shirt! I wore it to my aquaculture facility, where the #zebrafish all have jobs. They are helping us to learn all about developmental biology!

A woman in glasses with long brown hair standing in front of a zebrafish rack, which is a recirculating aquaculture system that can house thousands of small freshwater fish like zebra danios. She is wearing a blue shirt that features many fish dressed in human clothes and holding things implying they have occupations. The shirt says "we never left the water".

Best I could do

Taylor Swift album cover from The Life Of A Showgirl but instead of Taylor there is a whale shark coming straight at you, mouth agape and the title is The Life of a Megamama Supreme. and there's lots of rhinestones and red feathery stuff.

Fish that live in the open ocean all face the problem of water temperatures being cold, sometimes extremely so. This is an even bigger issue if you're a predator trying to chase down prey. So what's a cold-blooded fish to do? Let's talk about 1 solution for #FishOfTheWeek, gigantothermy

A whale shark swimming in the open ocean. It is a beautiful gray color with a unique pattern of white stripes and dots. The patterns are as unique as human fingerprints!

Oregon coho salmon making major recovery after facing extinction 🦑🌎🧪🐠

Once threatened with extinction, Oregon coho salmon could be removed from federal ESA list

Coho salmon numbers have greatly improved in Oregon's coastal rivers. They may qualify for removal from the Endangered Species Act in coming years.

Have you ever seen a baby gar eating?

This little Spotted Gar is about a week old and has started feeding on zooplankton (in this case brine shrimp/Artemia/ aka "sea monkeys").

#FishADay Monopterus albus Asian Swamp Eel. Widespread FW E and SE Asia. Adults & juveniles obligate air-breathers; earlier life stages absorb oxygen through skin. Makes control in introduced range hard--typical fish poisons are absorbed through gills. eu.naplesnews.com/story/news/2...

Move over iguanas. There's a new invasive species moving into Florida, the Asian swamp eel

The Asian swamp eel is an air-breathing fish that can move across land to new locations. Florida offers ideal habitat.

Sometimes, you don’t plan on doing science and science finds you! When my pet plecos died of natural causes, I was learning how to clear & stain fish for histology, so used these for practice to make art. I noticed something weird about their mouths, tho, and this paper was the result of that… 🐟 🐡

It may look as if this little one is practicing their dance moves — slow-slow-quick-quick — but we’re pretty sure fish can’t dance. It's more likely this bellowfish, or Notopogon sp., is taking advantage of snacks in the sediments, stirred up by the ROV's robotic arm during #uruguaysub200.
