This #SundayFishSketch is a little different. Last summer I illustrated a children's book about fish and fly fishing, and it was just published a few days ago! Now I'll be able to share the illustrations that I've had to keep hidden for so long 😄🐡

A photo of a newly published children's book called: The Perfect Catch of Tattoo Fish. The book has illustrations of fish and some fly fishing flies and each illustration comes as a temporary tattoo at the end of the book.

A work in progress illustration of a Pineapple Fish for today's #SundayFishSketch 🐡

A work in progress illustration of a Pinecone Fish. The fish is yellow, with black outlines between the scales. Imagine if a pineapple was turned into a fish, and instead of the green leaves, there were fins.

On this #EarthDay, let us also remember the species that are no longer with us 🐡 #ChinesePaddlefish

An illustration of a group of five Chinese Paddlefish. They swim near a silty river bottom, the water a greenish aqua. Rays of sun filter through the choppy water surface, illuminating the backs of the fish. Two fish are in the foreground, around the viewer's eye level; one fish is closer to the water's surface, nearly silhouetted against the reflected sky; and two fish are in the background, blurry and void of detail. The fish are swimming toward the right, with the lower left corner of the illustration fading into black. Chinese Paddlefish were declared extinct in 2020.

As a hobby artist who devotes waaay too many hours to an economically-unviable past-time, I have to take my victories where I can. So seeing my drawings in an exhibition and genuinely feeling that they belonged there (quality-wise) was a fantastic experience that I'll treasure for a long time.

Recently, all the AAAS Science & Tech Policy Fellows at EPA were terminated from our positions with little notice and for no clear reason. This effectively ended a partnership that had been going since 1980 and which had brought hundreds of scientists to the EPA as fellows, many of whom stayed. 1/7

Have been working on an illustration of Chiasmodon niger and decided to modify it a bit to fit today's #SundayFishSketch theme.

An in progress illustration of a Black Swallower fish. This fish lives in the deep sea and is brown to black in color with a long, thin body. It has a pretty large eye and very large mouth that leads to a stomach that can extend to several times its regular size, sometimes even becoming partly transparent. This allows the fish to eat prey larger than itself. In this illustration, I added some colorful Easter eggs in its stomach to fit with the Sunday Fish Sketch theme.

Climate science never said "we only have 12 years until we fall off a cliff" - but sadly, many thought it did; and even more sadly, that misleading message fed right into the script for Trump's WEF remarks today. Here's what the science has always said:

The conclusions of the IPCC's 1.5C report: every action matters, every bit of warming matters.
