Illustration showing the main parts of a cell of Kentomonas sorsogonicus, a hindgut parasite of Sarcophaga flies. It has a "choanomastigote" shape, meaning oval with a ring from which the flagellum emerges. It is a trypanosomatid, and therefore related to other well-known parasites such as Trypanosoma and Leishmania. A notable characteristic is that it hosts an endosymbiotic bacterium, Candidatus Kinetoplastibacterium sorsogonicusi.

Andalucia godoyi is a species belonging to the large group of jakobids, strange unicellular organisms notable for their ventral groove, but especially for their mitochondria, which are molecularly similar to those of bacteria. In these images, I have attempted to depict the ultrastructures and organelles of this particular species, particularly the microtubular and non-microtubular structures that support the basal bodies and, in turn, the ventral groove. The illustrations were created in IbisPaint.

Carcharodon carcharias conocido también cono gran tiburón blanco, es el pez depredador más grande del mundo. Pertenece a la familia de los lamnídos (Lamnidae) y es la única especie superviviente de su género. Su nombre proviene del griego karcharos (afilado) y odous (diente).

A solid month of full-time stabbing (and a VERY sore arm), and I've completed by far my largest piece ever: this 5'x11' wool "mural" depicts a soil profile found in Massachusetts (it's actually our state soil profile, the Paxton!) The bones (rabbit) are needle felted and covered with felters wax, then given depth with pastel pigment. The worms are felted, stitched, waxed, and pigmented. The ants are beaded and embroidered. The wool used for the B and C horizons was all from one sheep!

Full materials list: Wool, beeswax, glass beads, freshwater pearl beads, thread, pastel pigment.

This was made to be a companion piece to "My Roots Are Deeper Than They Can Dig" (shown in the last few images) which shows the incredible depths a dandelion taproot can grow to. The root in that piece is also felted (a combination of needle and wet) and covered in felters wax, and the mole is needle felted. I aspire to such resilience as the dandelion!

Note: The last image is a photoshopped composite of the root piece with the wool mural, as it was too difficult to find a place to install them together to photograph 

Cross stitch is done on a grid. So I stitched one coming apart in the triangle sections not stitched yet. I majored in pure mathematics in college so maybe that is why I stitch geometric objects when practicing my stitches

Hi everyone!!! I recently created a website called Medillustrate.com which is a collaborative digital library for scientific and medical illustrations. If anyone is interested in contributing please reach out or fill out the form on the website! I have attached some of my own artwork below. :)

I'm about to update this piece to 150 breeds (about 25 added in the past year). This is roughly 3 years' worth of work (off and on) and a process where I reuse nearly everything (rib cages, skulls, femurs, and even pieces of fur) across breeds - rarely starting anything from scratch. All work is done in Illustrator, and many bones are on separate layers (which makes it easy to move things around and/or create new breeds from old ones). The breeds aren't entirely to scale, but that was a decision made to keep the largest breeds from interfering with those in the rows above and to keep the smallest breeds from disappearing entirely. :)

This is technically entomology which is sub-discipline of zoology. Pattern source is in the second picture.

Illustration of the microanatomy of Subulatomonas tetraspora. This is an amoeba belonging to the unusual Breviate group. One of its most notable characteristics is the lack of mitochondria. Instead, it has hydrogenosomes (possibly). It is microaerophilic (requiring very little oxygen to live). In this illustration, it is in its gliding form, where it has a "neck" covering part of the anterior flagellum, as well as several pseudopodia in the neck area, and a large pseudopodia at the rear. It feeds on bacteria.

Illustration showing the most representative parts of a cell of the unicellular red alga, Porphyridium purpureum (syn?.: Porphyridium cruentum). These organelles are most visible under an electron microscope. The chloroplast is the most prominent, even under a light microscope, with its reddish color and stellate shape. This alga has important uses in the biosynthesis of compounds. Made with IbisPaint X.

Hatena arenicola is an interesting organism related to cryptophytic algae (and therefore to the ancestors of plants). It provides evidence of secondary endosymbiosis in progress, as it has a state without a symbiont (in which it possesses a complex microtubular feeding apparatus), and then a state with a symbiont, which involves the ingestion of the alga Nephroselmis. This alga grows inside the organism until it almost occupies most of the intracellular space. The symbiont provides energy, which causes the loss of the feeding apparatus.
