Spilogale
The genus ''Spilogale'' includes all skunks commonly known as spotted skunks. Currently, there are four accepted extant species: ''S. gracilis'', ''S. putorius'', ''S. pygmaea'', and ''S. angustifrons''. New research, however, proposes that there may be up to seven. Extant species In the past, anywhere between two and fourteen species of ''Spilogale'' have been recognized, but today most authorities accept a four species model (seen below). A 2021 DNA analysis of 203 specimens from across their known range suggests that there may be as many as seven distinct species in the genus, some cryptic. Description Mammalogists consider ''S. gracilis'' and ''S. putorius'' different species because of differences in reproductive patterns, reproductive morphology, and chromosomal variation. However, interbreeding has never been disproved. The name ''Spilogale'' comes from the Greek word ''spilo'', which means "spotted", and gale, which means "weasel". ''Putorius'' is the Latin word for " ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Western Spotted Skunk
The western spotted skunk (''Spilogale gracilis'') is a spotted skunk of western North America. Description With a total length of , the western spotted skunk is smaller than the striped skunk (''Mephitis mephitis''). Males, which weigh , are significantly heavier than females, at , but only about 6% longer, on average. The adult is boldly striped black and creamy white, with three longitudinal stripes on each side of the front part of the body, and three vertical stripes on the hind-parts. One pair of longitudinal stripes runs either side of the spine, with the second pair running over the shoulders, and extending forward onto the face. The third pair is lower over the shoulders, and curves downward at the middle of the body to form the first pair of vertical stripes. Behind this, the second pair of vertical stripes rise from the knees to the rump, while the final stripes are often little more than spots. In special cases, the normally black areas of the fur can appear in shades ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Eastern Spotted Skunk
The eastern spotted skunk (''Spilogale putorius'') is a small, relatively slender skunk found in North America, throughout the eastern United States and in small areas of Canada and Mexico. This small skunk is more weasel-like in body shape than the more familiar striped skunk. The eastern spotted skunk has four stripes on its back which are broken in pattern, giving it a "spotted" appearance. They have a white spot on their forehead. They are found in Canada (southeast Manitoba and northwestern Ontario), the United States and northeastern Mexico. Males, at in total length, are larger than females, at . The tail accounts for roughly a third of their total length. Body mass can range from , with males averaging around against the female's average of . Skull length is . The eastern spotted skunk is a very small skunk, no larger than a good-sized tree squirrel. They are much more active than any other type of skunk. They have mostly the same predators as any other skunk (big cats ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Spilogale Pygmaea
The pygmy spotted skunk (''Spilogale pygmaea'') is a species of mammal in the family Mephitidae. It is endemic to Mexico. Distribution and habitat The pygmy skunk inhabits along the Pacific coast of Mexico. It is found in woodlands and thickets in rocky soil. They avoid dense forests and swamps. It dens in burrows, but can take refuge in trees. Description The spotted skunks are the most similar to the weasels of the skunks. It has a slimmer body, and tail coat thinner and smaller than their close relatives. It reaches a length of 115–345 mm with a tail of 70–120 mm. Its coat has a black background with white spots on the forehead and characteristics of 2-6 white stripes on the back and flanks. The bands become spots on the back later. The tip of the tail is often white. Like all skunks, it has two large scent glands in the perianal region. Reproduction The mating season occurs in September or October, but the delayed implantation of the embryo lasts until March ...

Skunk
Skunks are mammals in the family Mephitidae. They are known for their ability to spray a liquid with a strong, unpleasant scent from their anal glands. Different species of skunk vary in appearance from black-and-white to brown, cream or ginger colored, but all have warning coloration. While related to polecats and other members of the weasel family, skunks have as their closest relatives the Old World stink badgers. Taxonomy In alphabetical order, the living species of skunks are: * Family Mephitidae ** Genus: ''Conepatus'' *** ''Conepatus chinga'' – Molina's hog-nosed skunk *** ''Conepatus humboldtii'' – Humboldt's hog-nosed skunk *** ''Conepatus leuconotus'' – American hog-nosed skunk *** ''Conepatus semistriatus'' – striped hog-nosed skunk ** Genus: '' Mephitis'' *** ''Mephitis macroura'' – hooded skunk *** ''Mephitis mephitis'' – striped skunk ** Genus: ''Spilogale'' *** ''Spilogale angustifrons'' – southern spotted s ...

Spilogale Angustifrons
The southern spotted skunk (''Spilogale angustifrons'') is a species of mammal in the skunk family, (Mephitidae). It ranges from Costa Rica to southern Mexico.

Description The southern spotted skunk grows to a length of with a tail length of and weighs between . It is conspicuously coloured in black and white and resembles the western spotted skunk in appearance. It has anal glands beneath the tail which secrete musk which can be sprayed with considerable accuracy at a predator. Distribution and habitat The southern spotted skunk is native to Central America where its range includes Mexico, Guatemala, Honduras, El Salvador, Nicaragua, Costa Rica and Belize. It is present at altitudes of up to in dry rocky areas with scrub and open woodland, and also in agricultural areas. Behaviours The southern spotted skunk is nocturnal and secretive in its habits.

El Salvador
El Salvador (; , meaning " The Saviour"), officially the Republic of El Salvador ( es, República de El Salvador), is a country in Central America. It is bordered on the northeast by Honduras, on the northwest by Guatemala, and on the south by the Pacific Ocean. El Salvador's capital and largest city is San Salvador. The country's population in 2022 is estimated to be 6.5 million. Among the Mesoamerican nations that historically controlled the region are the Lenca (after 600 AD), the Mayans, and then the Cuzcatlecs. Archaeological monuments also suggest an early Olmec presence around the first millennium BC. In the beginning of the 16th century, the Spanish Empire conquered the Central American territory, incorporating it into the Viceroyalty of New Spain ruled from Mexico City. However the Viceroyalty of Mexico had little to no influence in the daily affairs of the isthmus, which was colonized in 1524. In 1609, the area was declared the Captaincy General of Guatemala by t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sulfonic Acid
In organic chemistry, sulfonic acid (or sulphonic acid) refers to a member of the class of organosulfur compounds with the general formula , where R is an organic alkyl or aryl group and the group a sulfonyl hydroxide. As a substituent, it is known as a sulfo group. A sulfonic acid can be thought of as sulfuric acid with one hydroxyl group replaced by an organic substituent. The parent compound (with the organic substituent replaced by hydrogen) is the parent sulfonic acid, , a tautomer of sulfurous acid, . Salt (chemistry), Salts or esters of sulfonic acids are called sulfonates. Preparation Aryl sulfonic acids are produced by the process of sulfonation. Usually the sulfonating agent is sulfur trioxide. A large scale application of this method is the production of alkylbenzenesulfonic acids: :RC6H5 + SO3 -> RC6H4SO3H In this reaction, sulfur trioxide is an electrophile and the arene is the nucleophile. The reaction is an example of electrophilic aromatic substitution. Alkyl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
