Iconic California fish, iconic Italian historical figure and namesake Garibaldi. genomics and body color. I could not resist. onlinelibrary.wiley.com/doi/10.1111/...

Great oppor-TUNA-ty to brush up on your cool fish fun facts 🐠

Don't forget to check out our latest episode, all about the Tuna! There's so much more to those cans in your grocery store than you think! Find the episode and so many more on your podcatcher of choice!

Hemiscyllium dudgeonae is the tenth recorded species of walking shark, which use their pectoral fins to move across reef flats, and its limited range means it may be at high risk of extinction

My latest “organizations divers should know” column for SCUBA diving magazine is all about Field School, an inclusive marine science education organization I hire for all my field courses. They just celebrated ten years of operation! www.scubadiving.com/conservation... 🧪🦑🌎

Always funny to see how much their eyes are bulging outwards. 🐟 #photography #fishkeeping

Unsustainable fishing practices are the biggest threat to marine biodiversity. But solutions exist and should be promoted and celebrated- we’re absolutely not at the point where everyone has to give up seafood or the ocean is doomed. My book can help

Go fishing. It's fun, you can come home with good food, and it helps fund the conservation of Michigan's rivers, inland lakes, and #GreatLakes. The gear is an investment, but a license to fish all year is ridiculously cheap. #PureMichigan #Fishing #conservation www.canr.msu.edu/news/recreat...

Here I am securing a bonnethead shark while one of my students takes a small sample from it's fin. The water pump allows the shark to breathe during the workup. 🧪🌍🦑🦈

@solomonrdavid.bsky.social 70 lb lake sturgeon netted in Nebraska! (By fish and game doing paddlefish sampling) I’ve never seen one this big!

From pet to pest: A 2026 experiment reveals that releasing #goldfish into lakes triggers a full ecosystem regime shift, and no lake type is immune: m.economictimes.com/us/news/from... #fish #InvasiveSpecies #ecology #wildlife #animals 🌿

This is the first week in years where we're seeing significant traffic to the website from Olde Twitter. Looks like my piece on AI deep-sea animals is getting some attention over there. I'm not going to bother looking, but I wonder if they've adjusted how they handle linkouts?

Realized today that the dominant “Ruby Green” male is getting an additional sixth eggspot even though I have already kept him now for over two years. 🐟 #fishkeeping #photography

Ocean scientist here This isn’t funny Water only does this when it’s distressed

Yesterday a colleague from the Strib and I went electro fishing for gar with @solomonrdavid.bsky.social and his team. Story coming next week I expect. But this happened because Bluesky connects people.

Like all cardinalfish, the male is a “mouthbrooder”. There’s tons of cardinalfish species around Tulamben, and they’re usually overlooked as “ordinary” reef dwellers - bypassed in search of more exotic species, but I love them and their crazy parenting behaviors. This one is Ostorhinchus aureus.

One of the world's leading brain research centers is shifting away from fruit flies and toward a tiny, transparent fish. The goal: to understand how brains control the behavior of an animal or human. n.pr/4vV8dYM

Animal models continue to be critical to our understanding of complex biological and medical concepts. To learn more about the ethics and safeguards in place for responsible animal research, read this open-access article on the topic: www.nature.com/articles/s41...

I’m going to enjoy watching these baby Tapajos cichlids grow up.

ICYMI: My second book, "Why Sustainable Seafood Matters," is now available for preorder! Preorders are important because they signal interest to the market, and you can get 30% off list price by preordering using code HWSSM !

At the recent Sharks International 2026 conference, I was invited to present my research on the causes and consequences of public misunderstanding of shark conservation. Here's what I told Sharks International attendees. #SI2026 🧪🌍🦑🦈 #SciComm www.southernfriedscience.com/i-just-told-...

New episode this weekend! We're doing another Species Spotlight, all about the Tuna! Did you know that tuna are endothermic ("warm blooded") and they must keep swimming to breathe? You'll learn a lot about these incredibly powerful and fast fishes in this episode, find it on your podcatcher today!

Chain Pickerel #SundayFishSketch

The Trump administration keeps fighting against clean offshore wind energy, saying it kills whales (which is not true). And then they keep doing shit that actually kills whales, and no one calls them on it. www.americanprogress.org/press/statem...

Relic is a sub-adult female great white shark most easily recognized by a permanent notch in her caudal fin (tail) where the upper and lower lobes meet. This notch is not visible in this shot, due to how Relic is positioned.

One of the many great things about marine labs is that they often have aquaria featuring cool, local critters. #MarineLife 🌊🦑

For this lovely #sundayfishsketch a banded pygmy sunfish (Elassoma zonatum)! #sciArt #illustration #scicomm

#SundayFishSketch is here a day early because I’m in a wedding tomorrow. This is the deep water sculpin, inspired by the dive they did last weekend with a remote vehicle down to the deepest point of Lake Superior, Superior Maximus. There were lots of these little guys and one chased the ROV laser.

Sexual dimorphism in male (back) and female tubenose gobies! Collected from the upper St. Lawrence River.

Spawning Minnows! Among the great wonders of UK wildlife, unbeknownst to most of us, but to be found in our luckier rivers. My prize upon slipping into our local chalk stream, River Lark, Cavenham Heath, at start of Whitsun, suffering withdrawal from not having been in one since March. #MySwim 1/15

I’m taking a short break from painting sea turtles to post a Sunday Fish Sketch, a watercolor painting of a juvenile Pacific Sailfin Tang, Zebrasoma veliferum. #sciart #marinelife #coralreefs #sundayfishsketch

“Haplochromis” nubilus, one of the few Lake Victoria cichlids that also occurs outside the lake and seems to fall outside the LV radiation proper. Males are black with red borders on their unpaired fins. 🐟 #SundayFishSketch

Look at my new hat by @acorviart.bsky.social

Global cooperation needed to save sharks and rays populations

#SundayFishSketch 😻😻😻

This is absolutely NOT a scientifically valid #Dunkleosteus reconstruction. I read how they were likely built more like tuna than sharks, my imagination went off the rails, and now the scary #placoderm gets to feel like a pretty, pretty princess for #SundayFishSketch. #PaleoArt #illustration

Have you ever met the slough darter? Etheostoma gracile- this cute little critter is one of my newest illustrations. #sciart #scienceillustration #fishart

Redband trout in the Idaho high desert. #flyfishing.

Porcupine puffer fish are engaging and intelligent tropical fish. While they are known as masters of defense, they are also naturally very curious. But don't let their adorableness distract you; their potent toxin, tetrodotoxin, can be lethal to humans.

Absolutely NO BIAS toward number 9 on the list 😅🎣 www.outdoorlife.com/fishing/most...

Picked up an ink pen today instead for my #SundayFishSketch drawn from memory, a generic pleco. I think I better stick to crayon if I'm just going to rush it 😅

A couple of Atlantic tarpon glinting in the sunlight show us why they are known as Silver Kings. Prehistoric bony fish still swim amongst us 🫡🪩👑🐟 #tarpon #silverking #livingfossil #prehistoricfish #coralcitycamera

a salmon run? a limited run of salmon? it's more likely than you think hand screenprinted by the lovely @smdefelice.bsky.social with fun red/orange marbling available in the shop in limited quantity: acorviart.bigcartel.com

i love sharks 🦈 #art #sharks

At a particular port in Yakushima, you can see beautiful coral reef fishes during the day, and catch deep sea lantern fishes at night using a flashlight and dipnet
