Tullimonstrum, speeding close to the sea's surface. A second Tullimonstrum follows not far behind. The waves and water effects are dynamic, reflecting the high speeds reached by Tullimonstrum.

A new law demanding ID information for internet services comes into effect tomorrow. If I don't find a way to circumvent it, this will be the last artwork I get to post online. If the worst happens and I don't log back in, it was nice to draw with you :)

Sketch of the Argentine Torpedo (Tetronarce puelcha), a species of electric ray endemic to the southern ocidental Atlantic, specifically from southern Brazil, Uruguay and Argentina. This species is very rare and considered Critically Endangered, and very few image references are available for it.

Hey guys, just a heads up for those interested, I've made a VGen! I'll add anime girls and chibis to my services soon, but for now, I'm testing things with animal art. If you want an animal illustration, hit me up here:

Photo of the point I was fishing. In the bottom part, my fishing rod and a pink float are visible. I used a drifting float about 40cm depth and a small weight. I was catching catfish, so I tried bottom gear before, but there are snags like tree branches and old cages down there. Californian red worms as bait!

Rhamdia quelen. Native. 33cm long catfish.

Another angle of the native catfish I hooked. Flash photo since night was creeping in. No action during the afternoon, this species probably becomes more active during the night.

Overall picture of the broader part of the river. Under the place this was taken, an old sewer pipe (now mostly not connected, with few houses actually discharging waste in the river - most of the city is connected to the water treatment plant nowadays). I didn't fish here because of the smell, but I have seen tilapia, plecos, carp, and wolf fish swimming down there. About 20 meters to the right is the spot I used. Other fauna present includes turtles, birds like cormorants and cranes, and native ducks. Squirrels can be seen in the tree line, and capybaras often use the place too (beware the capy poop).

Went fishing in the nearby urban polluted river some days ago, and after changing my techniques and using red californian worms... I caught 'em!! Big and fat Rhamdia quelen catfish!! Added to my fishdex!!

More info in the alt texts (first time using them lol)
