We are getting some beautiful autumn weather here in NE. This season always evokes a sense of things coming to pass and a year coming to an end. Thus, the #SundayFishSketch #Fishytheme for this weekend is "lifecycles." Sketch a fish lifecycle, can be as simple or complex as you want! #sciart 🦑

Cuties with nasty behaviour. They like to nibble on whales, seals, humans, submarines... whatever 😬

1/2) Is that time of year again #Sundayfishsketch friends! This weekend marks the end of our 9th year of sketches! As we move into year 10, our annual #Fishytheme is to draw on Opah (the first fish sketch), to appreciate improvements made while practicing throughout the year. #sciart 🦑

This weekend’s #SundayFishSketch #Fishytheme will follow #inktober with the prompt of “Arctic.” Lots of really cool fishes to choose from that live in the Arctic! #sciart 🦑

At not even 5 days old, #sundayfishsketch ‘s newest member, Ava, would like her first #fishytheme to be “fishes with nurse/nursing in their name.” Take a look, there’s a couple! #sciart 🦑

Rolling into the weekend it is time for the #SundayFishSketch #Fishytheme. Continuing our @lizlagomorph.bsky.social #SciartSeptember themes, 'Reef' is the prompt for this Sunday! There are thousands of reef fishes to choose from, and I can't wait to see all the colorful illustrations! #Sciart 🦑

Continuing to follow our #SciartSeptember #SundayFishSketch #Fishytheme this month with @lizlagomorph.bsky.social, this weekend's theme is 'Mimic.' There are so many fantastic fish that mimic other things, including inanimate objects, other animals, even other fish! #sciart 🦑

For the week of September, #SundayFishSketch #Fishytheme s will be following along with @lizlagomorph.bsky.social #sciartseptember! That means, this Sunday's theme is "boreal!" There are so many fantastic northern/boreal fishes. I can't wait to see some sketches! #sciart 🦑

Are you looking for a #SundayFishSketch #Fishytheme to fill up your weekend? I've got one for you! We have an excessive heat warning in Nebraska, and extreme weather always makes me think of 'extremophile fishes.' Sketch those hot or cold loving, salinity or acidity loving, etc. fishes! #sciart 🦑

Tempted to have every #fishytheme this month just be all sorts of colorful, wonderful, #PrideMonth related #SundayFishSketch themes. Thoughts?! 🌈🐠🦑 #sciart

Repeated and widespread evolution of biofluorescence in marine fishes - Nature Communications Biofluorescence is widespread in fishes. Here, the authors compile data on biofluorescence presence across teleost fishes and demonstrate that it may have originally evolved in eels 112 million years ...

Apologies for missing the last few weeks for themes! In light of our new article www.nature.com/articles/s41..., the #Sundayfishsketch #Fishytheme is biofluorescent fishes! #sciart 🦑

For our #FishyTheme, we look to the warm waters of Brazil. Bursting with thousands of species, it may be difficult to choose a Brazilian fish for your #SundayFishSketch! #sciart 🦑

This weekend, people across the country are celebrating a particular holiday that often includes bunnies, eggs, chicks, and plenty of chocolate. For the #SundayFishSketch #Fishytheme I wanna see your rabbitfishes, roosterfish, crazy egg laying fish (chocolate fish?). Have fun with it! #sciart 🦑

This weekend’s #SundayFishSketch #Fishytheme is for all of us that are very much looking forward to spring and summer angling. Sitting in the boat or on the dock, enjoying nice weather and nature sounds. Let’s see some sketches of fishes you’d like to catch this year (wherever you are)! #sciart 🦑

2/2) The last year has been one heck of a ride. But, a #Fishytheme for the first time in a long time comes from @seetasaur.bsky.social who has asked if we could do "fishes on postage stamps." I believe this is a great way to kick off #SundayFishSketch themes again! #sciart 🦑

1/2) An apology to my #SundayFishSketch community for dropping the ball on #Fishytheme posts and participation. My time has been focused on my first semester teaching as a professor. We also purchased and moved into a new home. To top it off, I have a little fry incoming at the end of September.

A single line drawing of a pumpkinseed sunfish done in pen

for #SundayFishSketch this week, I stuck to the #FishyTheme and drew a pumpkinseed sunfish via a single line drawing! This was my first single line drawing ever and it was pretty tough. #sciart

A #sundayfishsketch #fishytheme I’ve wanted to do for a while is to sketch a fish using a single line, like this work by TFOUST. Let’s see those line drawings! #sciart

An acrylic pen drawing of a goldfish/comet.

First go with some acrylic paint pens I was given. Did you know you can use them on top of one another? A whole new world, though not necessarily easier. Carp or Goldfish are apparently lucky. I love goldfish. Luckily this house has a pond

Hopping back into the #Fishytheme for our 2025 #SundayFishSketch year, we will be sketching fishes that are supposed bring good luck (there are lots of choices)! We want to start this year off right. #sciart

"All I want for #25daysoffishmas (@drkatfish.bsky.social) this year" is the last set of clues for the #SundayFishSketch #Fishytheme. What a gargantuan effort from our artists this year! It's been great seeing #fishmas illustrations. Draw your mystery fish guess and post it this Sunday! #sciart 🦑🐡
