In honor of today's humidity in Wisconsin, it's a Florida coastal species, the Permit. I don't know anything about it but I picked it because of that freaky little face. #SundayFishSketch

Ink sketch of a fish with some long fins. Weird face, like an alien hybrid from one of the more recent Alien movies.

I heard it was also #SharkWeek and couldn't get the idea of a neon-filled whale shark mouth out of my mind. #Art

After seeing so much mola art in Hualien 花蓮，of course it had to be a sharptail mola 曼波魚 Masturus lanceolatus for my #TaiwanFishes #SundayFishSketch today! Hualien has somehow catapulted this species into a local mascot, although negative effects of increased harvests are TBD. #Taiwan #台灣魚類 🦑🐡🧪
