Microhierax latifrons - White-fronted Falconet
This tiny member of the Falconidae is a native to the island of Borneo, and is one of the smallest birds-of-prey in the world. The Siamese Rhinoceros Beetle (Xylotrupes gideon) is also native to Borneo, and is one of the largest and heaviest insects extant.
Unfortunately, the rhinoceros beetles don’t have the toxins and horrible taste that most of the other tropical insects have, making them the perfect prey for falconets.

“Star of India” Clematis
The clematis flowers are members of the Ranunculaceae family, which also includes the buttercups and the Acontium (wolfsbane or monk’s bane) genus. There are hundreds of species, and over a thousand cultivars of Clematus spp.
Found in European gardens (by way of the Japanese) by the 18th century, and in the United States since the mid-19th century, clematis flowers are hardy and perennial, but solely ornamental. Despite having a “pepper-like” taste, the seeds, sap, and everything else from the plant, is highly toxic, causing intense abdominal pain and intestinal bleeding when consumed.

Giant Golden Mole - Chrysochloris trevelyani [now Chrysospalax trevelyani]
If there were ever a mammal worthy of being given the common name of “Blorp”, this would be it. But no, they get to be called the “giant golden mole”, despite not being all that giant, or all that golden. I’m still calling them Blorps.
These pudgers are ancient, mostly-desert-dwelling Gondwanan creatures which are remarkably well adapted to climates with significant thermal shifts. During times of extreme heat or cold, their bodies can go into a state of torpor, almost stalling their basal metabolism rate, and completely turning off their internal thermoregulation until the temperature returns to a more amicable range.
The family of golden moles, Chrysochloridae, is not related to the “true moles” (Talpidae), but get their common name from their similar appearance, which developed through convergent evolution. Most scientists agree that the golden moles are more closely related to hedgehogs and shrews than to true moles, though some theories group them with the tenrecs. Until full genetic profiles are established for the Insectivoridae, we probably won’t have a definitive answer.

————————————————————————-
Though the Occupational Safety and Health Act as we [in the US] know it has only existed since 1970, there have been differing levels of federal oversight in the workplace since the Bureau of Labor was created as part of the Department of the Interior in 1888, and the Department of Labor was established in 1913. Though their oversight may not have been as stringent as what we have now, and laws may not have protected people as they do today, it was certainly better than nothing.
So what was working before ANY oversight like? Well, here are a few ways you could have died from your occupation, assuming you didn’t get killed by falling, getting crushed, getting impaled, or straight up getting ripped apart by the machinery (read: I’m not covering industrial disasters today; they’re coming later):
Aluminosis/Kaolinosis - Fibriod phthisis caused by the inhalation of clay dust.
Brass Founder’s Ague - A debilitating fever (often cyclical, like ague) caused by inhalation of the fumes of burned-down zinc, copper, or magnesium, in brass foundries.
Byssinosis - A lung disease caused by inhalation of cotton fiber dust or other vegetable fiber dust (flax, hemp, sissal). Leads to coughing, wheezing, progressive lung scarring and narrowing of the airways, and eventually death. Death isn’t so much due to the scarring, but more because of the highly reduced ability to fight pulmonary infections. Was particularly common in young girls and women, especially those in thread factories.
Caisson Disease - Spinal affection caused by either moving from a condensed atmosphere underground or a pressurized diving apparatus into the ground-level atmosphere again. Often occurs in conjunction with “The Bends”. Known as Diver’s Paralysis.
Cancer Scroti - …this is an awful one. A cancer noted by Percival Potts, affecting primarily chimney sweeps. Scrotal cancer, often appearing around puberty. Unfortunately was often treated as if it was a venereal disease, which wouldn’t have helped anything. Often led to the cancer spreading to the lymph nodes, leading to death before 18. Also known as Soot wart.
Danbury Shakes/Hatter’s Shakes - Symptoms of inhalation mercury poisoning exhibited by the hat-makers in Danbury, CT (the hat capital of the world in the 1800s). Often involved shaking, delirium, slurring speech, twitching, and a lurching gait. Sometimes these guys were mistaken for drunks.
Lacemaker’s Disease - Lead poisoning sometimes found in lace-makers.
Mad Hatter’s Syndrome - Differs from Danbury Shakes in that it more often leads to death, and is more often caused by unintentional ingestion of mercury (rather than inhalation). Involves severe ataxia, gastrointestinal symptoms, and emotional instability, in addition to the symptoms of Hatter’s Shakes.
Matches Disease - Oh god. Phossy jaw. Will do a full post on this and radium jaw soon. Caused by working with and inhaling the dust of white/yellow phosphorous, which was the primary ingredient in matches for a long time. Young girls and unmarried women were the primary makers of matches, and ended up the most affected by this disease. In the end, your jaw basically rots off and you go crazy and then you die. Also known as Phosphorus necrosis.
Potter’s Rot - Known as silicosis today. Caused by inhalation of silica particles often found in clay. Silica embeds itself deep in the alveolar sacs (meaning that it cant be coughed out), and the body, trying to get rid of the irritant, becomes inflamed and deposits collagen around the silica. This causes fibrotic nodules in the lungs, respiratory insufficiency, severe cough, fever, right ventricle heart disease, weight loss, and cyanosis. Silicosis leads to a significantly increased risk of tuberculosis and cancer, as well as mycobacterial infections. Also known as slate-worker’s lung/sandblaster’s asthma.
Ptilosis - Another form of fibroid phthisis, caused by inhalation of feather dust and down dust. In the ostrich feather industry of South Africa (which aside from pen quills, had a huge boom around 1880 thanks to the fashions of the time - feathers were prominent for over a decade, and came back in style frequently), this was particularly prevalent.
Rag Sorter’s/Rag-Picker’s Disease - Anthrax. Should do a post on the history of anthrax soon. Really interesting topic. Rag sorters were the women who sorted rags in the paper factories. Rag sorter’s disease often manifested itself as cutaneous anthrax, but pulmonary (inhalation) anthrax was not uncommon.
Sailor’s Fever - Yellow Fever. Almost always acquired in the tropics.
Silo-Filler’s Lung - Acute bronchiolitis fibrosa obliterans, caused by inhaling high levels of nitrogen oxides. Recently-filled silos have very high levels of nitrogen dioxide (which is one reason why you never want to be in a poorly-ventilated silo). Nitrous fume intoxication causes cough and shortness of breath, followed by high fever, chills, and a more serious shortness of breath. Death from pulmonary edema following the second phase was not uncommon.
Woolsorter’s “Pneumonia” - Inhalation anthrax. Anthrax spores are soil-borne, and when wool is sorted, it still carries the environmental dirt and grime that the sheep (who largely live outdoors) pick up. As the dirt is knocked free, soil-borne spores are also released. The sheep didn’t necessarily have to be infected itself to pick up anthrax spores as it lay on the ground. Though mortality rates from pulmonary anthrax hover around 45% these days thanks to early diagnosis, improved treatment, and (most of all) Pasteur’s anthrax vaccine for livestock, historic mortality rates were ~92%. Pretty awful thing to catch in the workplace.
Cockatoo in Flight
Prior to the first motion pictures, Eadweard Muybridge produced a series of stop-motion photographs of animal movement in 1877, which, when viewed in succession, effectively produce the first “moving pictures”.
Cockatoo are a good example of a bird which uses primarily non-gliding (flapping) flight. During the downstroke (power stroke), the wing moves forward and downward, producing thrust. The upstroke, or recovery stroke, involves the flight feathers separating, to allow the air to flow through them. This, combined with the wing partially folding in towards the body, reduces drag significantly.

Underside and circulatory system of the Atlantic Horseshoe Crab (Limulus polyphemus)
The curious horseshoe crab (or king crab) is not actually a crab at all. It is an ancient member of the Chelicerata - more closely related to scorpions and spiders than any crustacean.
Note that the colors on the bottom illustrations only indicate a state of oxygenation and deoxygenation (red and blue, respectively), not the true color of the blood. Since horseshoe crabs utilize the copper-based hemocyanin to transport oxygen (as opposed to hemoglobin, in vertebrates), their blood is colorless or a light yellow when oxygenated, and a deep blue color when deoxygenated.
Of note - the mouth of the horseshoe crab is a jawless opening leading to a gizzard, between the legs on the underside of the body, and the book gills are located directly below them. The book gills, in addition to being used for blood gas exchange, are occasionally used for increased motility.

Speaking of Lazarus taxon…
Front View of Muntjac Skull
The muntjac is native to South Asia, but has been introduced to some parts of England, and is considered an invasive species there. The general build of this small deer is similar throughout the genus, with a short stature, short and single-pointed antlers, and tusks.
Muntjacs are also considered the oldest genus of deer extant, having originated at least 30 million years ago (as compared to white-tailed and mule deer, whose direct ancestor evolved less than 5 million years ago). Despite this, and their genetic similarities on an mtDNA level, the various species of the genus are very interesting to geneticists on account of their chromosomal differences. The Indian Muntjac has a diploid number of only 7 in the males, and 6 in the females, while the Reeve’s Muntjac has a diploid number of 46. That’s a huge difference in one genus, and we’re still trying to make sense of how the species can be so similar, yet so incredibly different!

Darwin’s Most Influential Works
Though Charles Darwin’s works on the function of earthworms, soil fertility, and phototropism had far more of an initial impact (and are still used to this day as a basis of our knowledge of certain plant and Annelid behaviors), these three books have had a much more far-reaching impact, and helped steer biology to a place where evolution plays a role in nearly every sub-specialty.

Top: Dorsal view and pectoral limb of Manatus americanus (now Trichechus manatus)
Bottom: African Elephant (Loxodonta africana)
These two creatures, though vastly different, are actually some of the most closely related extant sea and land mammalia.
Though the transition from land to sea occurred around the same time, the Sirenians (dugongs and manatees) are only distantly related to the Pinnipedia (seals and sea lions) and Cetacea (whales). The only living ocean-dwelling mammalian herbivores, Sirenians split off from a common ancestor with elephants around the middle of the Eocene epoch. This pig-like creature was very distinct from the small deer-like creatures that led to both the Cetaceans and modern horses.
The manatee’s land-dwelling origins can be seen in their pectoral limbs - there are “fingernails” at the end of each flipper, much more similar to the fingernails on an elephant’s foot than the claw-like nails you can see on the Pinnipedia.

IF YOU MASTURBATE YOU’RE GONNA GET DIABETES
apparently.
Welp, that’s a new one.
I don’t think I’ve ever seen “diabetes caused by masturbation” before. I mean, it apparently causes every other problem out there, why not add diabetes to the list?
