Happy Crablentine's Day everyone. Calappa calappa x Phalaenopsis amabilis Coenobita rugosus x Macodes petola Paromola cuvieri x Paphiopedilum sanderianum Allogalathea elegans x Vanda suavis #Art #SciArt

Single line drawing of a red swordtail for this week's #SundayFishSketch theme. #SciArt

A drawing of a ruffe, species uncertain. They are invasive in the Great Lakes and outcompetes several native fish. #SundayFIshSketch. #SciArt

For #Invertefest An ox beetle, I think. Strategist sp. This one flies around at night as if blind, bumping into things and buzzing around wildly. Quite large, maybe an inch long.

This week's #SundayFishSketch riddle... Rainbow dace=red horse minnow=red shiner... There's probably a few more name variants. #SciArt

I started a Chinook Salmon sketch for the #SundayFishSketch riddle. Couldn't decide if it was Chinook, Coho or Kokanee Salmon, or maybe another... All wrong, but I completed the sketch anyway. #SciArt

Spotted an 8 inch blue crab in a pond near Naples FL. Reminded me of one I sketched a while back. 🦀🦑 #SciArt #MarineLife

#SciArt too

Eurasian Ruffe, Gymnocephalus cernua, for #SundayFishSketch theme of "blue". It's not really very blue, but has blue shades on its fins and belly. Unfortunately this is an invasive species in North America, outcompeting many native fish. I drew this as part of a study of invasive species.

A Round Goby posted for #SundayFishSketch #SciArt This is an invasive species in North America. See www.invadingspecies.com/invaders/fis...

Sorry I meant #SundayFishSketch

Didn't have much time to draw today. A very rough sketch of a moutherbreeder Chiclid with some fry. No particular species. This is for the #SundsyFishSketch theme of "family". Mouthbreeders protect their fry in their mouth! #SciArt

Here's my take for this week's #SundayFishSketch .. my overlay on a photo of a fossil Pycnodontiformes. #SciArt

Portrait of a 'Pede Everyone's favorite giant millipede, Arthropleura, finally has a face 150+ years after its discovery. Most notably: it had crab-like eyestalks. This is my unofficial take of the situation. #Art #SciArt

For this week's #SundayFishSketch with a theme of mimicry. I drew a Corydoras duplicareus catfish. In the wild, these may exhibit as many as 3 types of mimicry... Crypsis, Bayesian and Mullerian. And they really are cute. #SciArt Reference cefishessentials.com/blog/corydor...

This is technically last week's #InsertAnInvert2024 theme, mesopelagic, representing a slipper lobster (Scyllaridae) larva riding a jellyfish (Pelagia noctiluca). They are part of the largest migration on earth every night from the deep sea. I experienced this blackwater diving earlier this year 🧪🦑

Keeping with this week's #SundayFishSketch theme of "fangs", here is a needle fish common to tropical reefs. It has a long snout with small teeth (fangs?) to snare it's food, usually smaller fish. #SciArt

A hermit crab for #invertefest

A bit late for #SundayFishSketch... In the theme of schooling, 3 neon tetras, my favorite schooling aquarium tank fish. Or maybe I prefer other tetras, too difficult to decide. #SciArt

Also inspired to post a catfish #SundayFishSketch #SciArt

A goby for #SundayFishSketch. Not sure what the theme is this week, but I had this sketch hanging around. #SciArt

A horseface loach for this week's #SundayFishSketch theme of fish from Thailand. We had one in our aquarium... It disappeared for 2 years, then arrived as king of the tank. #SciArt

#SundayFishSketch #SciArt A drawing of a "crappie" (sun fish) from the Laurentian mountains north of Montreal. Perhaps a bit of artistic license involved

#InsertAnInvert2024 #SciArt

Mitten Crab for #InsertAnInvert2024 . Native to parts of South Asia, they are considered an invasive species and banned in many other parts of the world. #SciArt

A blue crab drawing for #insertaninvert2024, Callinectes Sapidus. Blue crabs are nasty, and being swimming crabs, can move relatively freely. #sciart

A drawing of 2 green killifish for #SundayFishSketch This is a brackish water fish that I often see in temporary ponds. #SciArt

For this week's Insert an Invert. Zebra mussels, a freshwater scourge. I drew these as part of a diorama of invasive species in northern fresh water systems. #InsertAnInvert2024

@franzanth.bsky.social refused to suggest tardigrade for #InsertAnInvert2024 but the googledoc for "around logs" mentions mosses. Which is where tardigrades are found! They are indeed all around us 🥰

A favorite of mine, a hermit crab #invertefest #sciart

Also for #invertefest, I can't leave out the monarch caterpillar

For #invertefest, a sketch of a classic monarch butterfly.

Now that #InverteFest is really hitting its stride, here's a new artistic contribution by my dad! The man o war jellyfish, Physalia physalis 🦑🪼
