Today is World Rhino Day! Sumatran rhinos are the smallest of all rhinos. They are also one of the rarest and most endangered mammals in the world with fewer than 100 individuals left in the wild.  #rhino, #sciart, #WorldRhinoDay, #scientificillustration

It’s World Turtle Day! Here’s the skull of a common snapping turtle (Chelydra serpentina). These prehistoric-looking freshwater turtles live in Canada and the U.S. Snapping turtles are omnivorous but they are also scavengers and active hunters #sciart, #turtle, #worldturtleDay #anatomy

Spotted in the wild! While I was creating this Great White Shark illustration for BioRender, I wondered how it would be used in the future. It’s great to see it in a peer-reviewed publication. This interesting research quantifies growth changes in white sharks to aid in their conservation. #SciArt

Happy 573rd Birthday Leonardo! Leonardo is one of my heroes for many reasons but especially for his medical and scientific illustrations. If published during his lifetime or shortly thereafter, instead of in the late 1800s, his anatomical works would have advanced medicine by a couple of centuries.

Happy International Beaver Day. #InternationslBeaverlDay #SciArt #SciComm #VizSciComm #anatomy #AnimalAnatomy #skull This illustration was created for my book, The Dissection of Vertebrates. The fourth edition, which is currently in the works, will have many updates and plenty of new content.

It’s that time of year again when I’d like to share my annual scientific holiday card. I’ve been wanting to create a card depicting deer antlers and tie it in with the holiday season. Here’s what I came up with …. Happy holidays and all the best for the new year!  #SciArt  #VisSciComm

Here’s a creative summary of my 12 Days of Anatomy sung and narrated by the talented Erica Brookhyser and video editing created by Christina Smith. special thanks to Erica for contacting me and collaborating together on this fun project.

What better way to end the 12 days of Anatomy than on the winter solstice. On the twelfth day of anatomy class my instructor gave to me …. 12 cranial nerves All vertebrates from fish to mammals have twelve pairs of cranial nerves #medart #sciart #anatomy, #12DaysofAnatomy

On the eleventh day of anatomy class my instructor gave to me …. 11 organ systems #medart #sciart #medsky #anatomy, #12DaysofAnatomy

On the tenth day of anatomy class my instructor gave to me …. 10 feet of ileum The ileum is ~300cm which makes it the longest and final segment of the small intestine #medart #sciart #medsky #anatomy, #12DaysofAnatomy

On the ninth day of anatomy class my instructor gave to me …. 9 abdominal regions #medart #sciart #medsky #anatomy, #12DaysofAnatomy

On the eighth day of anatomy class my instructor gave to me …. 8 cranial bones The cranial bones form the brain case that protects the brain #medart #sciart #medsky #anatomy, #12DaysofAnatomy

On the seventh day of anatomy class my instructor gave to me …. 7 tarsal bones Tarsal bones form the ankle and the back half of the foot #medart #sciart #anatomy, #12DaysofAnatomy #skymed

On the sixth day of anatomy class my instructor gave to me …. 6 eye muscles These extra ocular muscles controlling eye movement are found in almost all vertebrates from fish, like sharks shown here, to humans #medart #sciart #medsky #anatomy, #12DaysofAnatomy

On the fifth day of anatomy class my instructor gave to me …. 5 lumbar vertebrae. The number of lumbar vertebrae in mammals is variable, but humans have five. #medart #sciart #medsky #anatomy, #12DaysofAnatomy

On the fourth day of anatomy class my instructor gave to me …. 4 chambered heart #medart #sciart #medsky #anatomy, #12DaysofAnatomy

On the third day of anatomy class my instructor gave to me …. 3 ear (auditory) ossicles These tiny bones in the middle ear transmit vibrations from the outer ear into the inner ear so they can be processed as sound #medart #sciart #medsky #anatomy, #12DaysofAnatomy

On the second day of anatomy class my instructor gave to me …. 2 turtle dove skeletons #medart #sciart #medsky #anatomy, #12DaysofAnatomy

For the next ~2 weeks I’ll be creating posts for the “12 Days of Anatomy”. I’m breaking tradition and arbitrarily starting my 12 days of anatomy today. On the first of anatomy class my instructor gave to me …1 trachea attached to a bronchial tree #medart #sciart #anatomy, #12DaysofAnatomy #medsky
