One of these things is not like the other…

First row: Walrus (Odobenus rosmarus) skeleton
Second row: Hooded seal (Cystopkora cristata) skeleton
Third row: Dugong (Dugong dugon) skeleton, Brazilian sea lion (Otaria flavescens) skeleton.

*Skulls depicted are of species in the same genus as the skeleton.

Sirenia (manatees, dugongs, and sea cows) and Pinnipedia (the seals, walruses, and sea lions) are often seen as very similar, but they came from very different lineages.

While both came from land mammals (just like all sea mammals), the pinnipeds evolved from a bear-like ancestor, who returned to the sea around 28 MYA. They’re Caniformidae, or dog-like Carnivora.

The sirens evolved from the same ancestor as the hyraxes and elephants, and returned to the sea around 50 MYA. They’re only distantly related to Cetaceans and Pinnipeds.

Male Reproductive Organ - Lachesis rhombeata (now Lachesis muta rhombeata)

Like other Squamates (snakes and lizards), the male Atlantic forest bushmaster (Lachesis muta rhombeata) possesses a reproductive organ known as the hemipene, or hemipenis. It has two heads, and is generally heavily spiked on both heads. The organ retracts into the tail of the animal when it’s not mating, and is one of the defining characteristics of the order Squamata.

Aconitum variegatum - Wolf’s Bane, Monkshood
Aconitum is thought to be from the Greek ἀκόνιτον - “without struggle”. And it is without struggle that this plant causes death.
This beautiful perennial flower can be seen through the autumn months in forests and taigas in Europe, and is popular as an ornamental in gardens, lending color long after summer blooms have faded.
It can also be found in the traditional bikh poison, nepaline, in the writings of Ovid and Dioscorides, and in the bodies of murdered Borgia family members.

Skeleton of the Grivet (Cercopithecidae aethrops)
Grivets are Old-World monkeys that live in large packs in Ethiopia and the surrounding areas in East Africa. Despite not having prehensile tails (part of being an Old-World primate), are fairly arboreal creatures. Their long tails still come in handy, though - they’re used in balance much like cats use their tails.
These monkeys are extremely omnivorous. They’ll eat anything from fruits, to edible leaves, to fish, to other meats. They’ve been observed snatching small birds out of midair and eating them, after scaring them out of their nests (which they then raid for eggs).

Northern Wolverine - Gulo borealis (now recognized as a sub-population of Gulo gulo luscus)
Check out the huge paws and the distance from the ribcage to the edge of the body - the thick, oily fur, and the fat padding keep the wolverine resistant to frost, and the big paws allow it to “snowshoe” across the winter tundra. Well, that, and they help them take down prey as large as mule deer and moose calves. 
Wolverines are the largest (or at least most powerful) carnivores active throughout the year in most holarctic regions of the world.

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.

Paeonia officinalis - European Peony
The European peony is one of the oldest cultivated species of peony, and also one of the most uncommon to be found in gardens these days. They can still be found wild throughout Europe, however.

Lathyrus grandiflorus -The Two-Flowered Everlasting Pea
The everlasting pea is a species of the genus Lathyrus (pea plants) that’s indigenous to Great Britain. It doesn’t set down seed well, and is not considered healthy to eat, when it does (much like the sweet pea).
However, despite its difficulty of cultivation in a home garden, everlasting peas are still popular ornamentals, and the seedlings are available at most greenhouses and nurseries throughout Europe. The tendrils that you see at the end of each stem will climb trellises and other plants easily, so it’s inadvisable to plant everlasting peas near any other herbaceous growths.

Canis Zorda [now Vulpes zerda] - Fennec Fox
The Fennec fox is indigenous to Northern Africa, especially around Morocco, but is common in zoos around the world. Their large ears dissipate the heat of the desert, and their thick fur keeps them warm during the surprisingly-cold nights of the Sahara. They’re the smallest canid in the world, and often weigh less than 3 lbs as adults. Despite their tiny size, their ears can reach up to six inches across. Like many desert residents, Fennecs are opportunistic feeders. They consume eggs of birds and reptiles, rodents, and reptiles themselves, as well as a large number of insects.
Interestingly, the Fennec fox’s paws are much more similar to the Arctic foxes than any other fox species. They’re large and fur-covered, which protect them from the blisteringly-hot sand, rather than the frigid snow and ice.

Top: Fossil Megaloceros giganteus with grown man for comparison.

Bottom: Approximation of Megaloceros giganteus in continental European environment.

The Irish Elk (Megaloceros giganteus), which wasn’t really an elk at all, wasn’t actually “Irish”, either. Though its fossils have been extensively preserved in the Irish peat bogs, and were first found in Ireland, this cervid lived throughout Eurasia, all the way east to Lake Baikal.

Their proposed extinction during the last major ice age has been disputed recently, with the dating of more recent bone caches. The current date that’s generally accepted for their (effective) extinction is around 7600 years ago.

Angeiographie
Vascularization of the organs and muscles. The viscera requires an amazing amount of oxygenated blood to do its job properly, which is one of the many reasons you don’t want to get shot in the gut.
Note the inclusion of the veins that go from the intestines to the liver in the top right quadrant of this plate (the image with the blue vessels) - the hepatic portal vein is not a “true” vein, in that it does not take deoxygenated blood back to the heart and lungs, but it takes nutrient-rich blood from the GI tract into the capillary beds of the liver for processing.

“Mad dog”
This 1826 cartoon depicts a “mad dog” in the London streets, attacking people. You can note the “Hydrophobia!” warning posted in the upper left-hand side of the caricature.
Rabies was definitely a thing people wanted to avoid, and was especially terrifying because they didn’t understand anything useful about the virus. All they knew was if you got bit by a mad dog, you had less than a year before you went dumb or manic and then ended up dead, yourself…at least if your bite wound didn’t get infected and kill you before then!
