The coyote is a species of canine native to North America. It is smaller than its close relative, the wolf, and slightly smaller than the closely related eastern wolf and red wolf. It fills much of the same ecological niche as the golden jackal does in Eurasia. The coyote is larger and more predatory and was once referred to as the American jackal by a behavioral ecologist. Other historical names for the species include the prairie wolf and the brush wolf.
The Appalachian Mountains, often called the Appalachians, are a mountain range in eastern to northeastern North America. Here, the term "Appalachian" refers to several different regions associated with the mountain range, and its surrounding terrain. The general definition used is one followed by the United States Geological Survey and the Geological Survey of Canada to describe the respective countries' physiographic regions. The US uses the term Appalachian Highlands and Canada uses the term Appalachian Uplands..
Millipedes are a group of arthropods that are characterised by having two pairs of jointed legs on most body segments; they are known scientifically as the class Diplopoda, the name derived from this feature. Each double-legged segment is a result of two single segments fused together. Most millipedes have very elongated cylindrical or flattened bodies with more than 20 segments, while pill millipedes are shorter and can roll into a tight ball. Although the name "millipede" derives from Latin for "thousand feet", no species was known to have 1,000 or more until the discovery in 2020 of Eumillipes persephone, which can have over 1,300 legs. There are approximately 12,000 named species classified into 16 orders and around 140 families, making Diplopoda the largest class of myriapods, an arthropod group which also includes centipedes and other multi-legged creatures.
Centipedes are predatory arthropods belonging to the class Chilopoda of the subphylum Myriapoda, an arthropod group which includes millipedes and other multi-legged animals. Centipedes are elongated segmented (metameric) creatures with one pair of legs per body segment. All centipedes are venomous and can inflict painful stings, injecting their venom through pincer-like appendages known as forcipules or toxicognaths, which are actually modified legs instead of fangs. Despite the name, no centipede has exactly 100 pairs of legs; number of legs ranges from 15 pairs to 191 pairs, always an odd number.
The red-backed salamander is a small, hardy woodland salamander species in the family Plethodontidae. It is also known as the redback salamander, eastern red-backed salamander, or the northern red-backed salamander to distinguish it from the southern red-backed salamander. The species inhabits wooded slopes in eastern North America, west to Missouri, south to North Carolina, and north from southern Quebec and the Maritime provinces in Canada to Minnesota. It is one of 56 species in the genus Plethodon. Red-backed salamanders are notable for their color polymorphism and primarily display two color morph varieties, which differ in physiology and anti-predator behavior.
Myriapods are the members of subphylum Myriapoda, containing arthropods such as millipedes and centipedes. The group contains about 13,000 species, all of them terrestrial.
The eastern wolf also known as the timber wolf, Algonquin wolf or eastern timber wolf, is a canine of debated taxonomy native to the Great Lakes region and southeastern Canada. It is considered to be either a unique subspecies of gray wolf or red wolf or a separate species from both. Many studies have found the eastern wolf to be the product of ancient and recent genetic admixture between the gray wolf and the coyote, while other studies have found some or all populations of the eastern wolf, as well as coyotes, originally separated from a common ancestor with the wolf over 1 million years ago and that these populations of the eastern wolf may be the same species as or a closely related species to the red wolf of the Southeastern United States. Regardless of its status, it is regarded as unique and therefore worthy of conservation with Canada citing the population in eastern Canada as being the eastern wolf population subject to protection.
A coywolf is a canid hybrid descended from coyotes, eastern wolves, gray wolves, and dogs. All of these species are members of the genus Canis with 78 chromosomes and therefore can interbreed. One genetic study indicates that these two species genetically diverged relatively recently. Genomic studies indicate that nearly all North American gray wolf populations possess some degree of admixture with coyotes following a geographic cline, with the lowest levels occurring in Alaska, and the highest in Ontario and Quebec, as well as Atlantic Canada. Another term for these hybrids is sometimes wolfote.
Scolopendra gigantea, also known as the Peruvian giant yellow-leg centipede or Amazonian giant centipede, is a centipede in the genus Scolopendra. It is the largest centipede species in the world, with a length exceeding 30 centimetres (12 in). Specimens may have 21 or 23 segments. It is found in various places throughout South America and the extreme south Caribbean, where it preys on a wide variety of animals, including other sizable arthropods, amphibians, mammals and reptiles.
Sistrurus miliarius, commonly called the pygmy rattlesnake, is a species of venomous snake in the subfamily Crotalinae of the family Viperidae. The species is endemic to the Southeastern United States. Three subspecies are currently recognized.
Ethmostigmus rubripes, commonly known as the giant centipede, is a species of centipede in the family Scolopendridae. It is a solitary nocturnal predator found across Asia and Oceania, with three subspecies currently described.
Scolopendra is a species-rich genus of large tropical centipedes of the family Scolopendridae.
Preble's shrew is a small shrew distributed across the Great Basin of the United States and southern British Columbia in Canada.
Scolopendra morsitans, also known as the Tanzanian blue ringleg or red-headed centipede, is a species of centipede in the family Scolopendridae. S. morsitans is the type species for the genus Scolopendra.
Himantariidae is a monophyletic family of centipedes in the order Geophilomorpha and superfamily Himantarioidea, found almost exclusively in the Northern Hemisphere. The number of leg-bearing segments in this family varies within as well as among species and ranges from 47 to 181. These centipedes are very elongated with a high mean number of trunk segments and great variability in this number within species. The maximum number of legs recorded in this family appears in the species Chomatobius bakeri. The minimum number of legs recorded in this family appears in the species Garriscaphus oreines, This family contains these genera:
Hiltonius is a genus of cylindrical millipedes in the family Spirobolidae comprising 10 species ranging from the southwestern United States to Guatemala, with most species being found in Mexico. The genus was named by Ralph Vary Chamberlin in 1918, after Professor William A. Hilton of Pomona College who collected the type specimen of H. pulchrus.
Plutonium zwierleini, in the monotypic genus Plutonium, is one of the largest scolopendromorph centipedes in Europe, and one of the few potentially harmful to humans. Nevertheless, it has been rarely reported, only from the southern part of the Iberian and Italian peninsulas, Sardinia and Sicily.
Scolopocryptops is a genus of bark centipedes in the family Scolopocryptopidae. There are over 20 described species in Scolopocryptops.
Hemiscolopendra is a genus of bark centipedes in the family Scolopendridae. There are about six described species in Hemiscolopendra, found in North, Central, and South America.
Geophilus vittatus, also known as the diamondback soil centipede, is a species of soil centipede in the family Geophilidae widespread in North America and named for the dark band of diamond-shaped markings across its back. G. vittatus grows up to 52 millimeters in length, though it averages 25–40, and ranges from brown- to orange-yellow in color, with 49–53 leg pairs in females, 49–51 leg pairs in males, and a lack of consolidated carpophagus structures. It can be found under any debris on the forest floor, but mostly under loose bark and occasionally near the sea.
