Southern Rubber Boa
''Charina umbratica'', known commonly as the southern rubber boa, is a species of snake in the family Boidae. The species is endemic to the United States, in southern California. Taxonomy The southern rubber boa, also known as ''Charina umbratica'', has been proposed as an independent species because of its morphological and geographic differences. A study published in 2001 concluded that ''Charina umbratica'' is separated from its subclade. This means that the southern rubber boa and its subclades have allopatric distributions. All evidence gathered from the mitochondrial DNA study points to consider ''Charina umbratic'' as a distinct species. Despite the distinction of the two subclades, a more recent study suggests that grounds for distinction of clades may be invalid as range movements may not be as thoroughly studied and contextualized as previously considered. Conservation status As of April 2017, the southern rubber boa was listed as a state threatened species in the Cal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Laurence Monroe Klauber
Laurence Monroe Klauber (December 21, 1883 in San Diego, California – May 8, 1968), was an American herpetology, herpetologist and the foremost authority on rattlesnakes. He was the first curator of reptiles and amphibians at the San Diego Natural History Museum and Consulting Curator of Reptiles for the San Diego Zoo. He was also a businessman, inventor, and contributed to mathematics in his study of the distribution of prime numbers. Biography The youngest of Theresa Epstein and Abraham Klauber , Abraham Klauber's twelve children, Klauber was born on December 21, 1883 in San Diego, California. He received his A.B. degree (Electrical Engineering) from Stanford University in 1908 and completed a Westinghouse graduate apprenticeship course in 1910. He married Grace Gould in 1911, and in that same year began his career with San Diego Gas & Electric Company. He received an honorary LL.D. from the University of California, Los Angeles in 1941. Klauber died on May 8, 1968 in San Dieg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
California Whipsnake
The California whipsnake (''Masticophis lateralis''), also known as the striped racer, is a colubrid snake found in habitats of the coast, desert, and foothills of California. Description ''Masticophis lateralis'' is in total length (including tail). It is slender, with a yellowish stripe along each side, set against a dark brown or black back. Diet The California whipsnake is known to eat a variety of live animals including insects, lizards, snakes, birds, and small mammals.Swaim KE (1994). ''Aspects of the Ecology of the Alameda Whipsnake'' (Masticophis lateralis euryxanthus). Upublished Master's Thesis, California State University, Hayward. 140 pp. It shows a strong preference for lizards, which are captured by a grasp of the mouth, and swallowed alive. Behavior ''Masticophis lateralis'' is fast-moving, diurnal, and an active forager. It commonly moves over and through brush and trees to avoid predation and to capture prey. The California whipsnake has been observed movin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reptiles Of The United States
Reptiles, as most commonly defined are the animals in the class Reptilia ( ), a paraphyletic grouping comprising all sauropsids except birds. Living reptiles comprise turtles, crocodilians, squamates (lizards and snakes) and rhynchocephalians (tuatara). As of March 2022, the Reptile Database includes about 11,700 species. In the traditional Linnaean classification system, birds are considered a separate class to reptiles. However, crocodilians are more closely related to birds than they are to other living reptiles, and so modern cladistic classification systems include birds within Reptilia, redefining the term as a clade. Other cladistic definitions abandon the term reptile altogether in favor of the clade Sauropsida, which refers to all amniotes more closely related to modern reptiles than to mammals. The study of the traditional reptile orders, historically combined with that of modern amphibians, is called herpetology. The earliest known proto-reptiles originated around 31 ...

Snakes Of North America
Snakes are elongated, limbless, carnivorous reptiles of the suborder Serpentes . Like all other squamates, snakes are ectothermic, amniote vertebrates covered in overlapping scales. Many species of snakes have skulls with several more joints than their lizard ancestors, enabling them to swallow prey much larger than their heads (cranial kinesis). To accommodate their narrow bodies, snakes' paired organs (such as kidneys) appear one in front of the other instead of side by side, and most have only one functional lung. Some species retain a pelvic girdle with a pair of vestigial claws on either side of the cloaca. Lizards have evolved elongate bodies without limbs or with greatly reduced limbs about twenty-five times independently via convergent evolution, leading to many lineages of legless lizards. These resemble snakes, but several common groups of legless lizards have eyelids and external ears, which snakes lack, although this rule is not universal (see Amphisbaenia, Dibamida ...

Ring-necked Snake
''Diadophis punctatus'', commonly known as the ring-necked snake or ringneck snake, is a harmless species of colubrid snake found throughout much of the United States, central Mexico, and south-eastern Canada. Ring-necked snakes are secretive, nocturnal snakes, so are rarely seen during the day time. They are best known for their unique defense posture of curling up their tails, exposing their bright red-orange posterior, ventral surface when threatened. Ring-necked snakes are believed to be fairly abundant throughout most of their range, though no scientific evaluation supports this hypothesis. Scientific research is lacking for the ring-necked snake, and more in-depth investigations are greatly needed. It is the only species within the genus ''Diadophis'', and currently 14 subspecies are identified, but many herpetologists question the morphologically based classifications. Description Ring-necked snakes are fairly similar in morphology throughout much of their distribution. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kingsnake
Kingsnakes are Colubridae, colubrid New World members of the genus ''Lampropeltis'', which includes 26 species. Among these, about 45 subspecies are recognized. They are nonvenomous and ophiophagy, ophiophagous in diet. Description Kingsnakes vary widely in size and coloration. They can be as small as 24" (61cm) or as long as 60" (152cm). Some kingsnakes are colored in muted browns to black, while others are brightly marked in white, reds, yellows, grays, and lavenders that form rings, longitudinal stripes, speckles, and saddle-shaped bands. Most kingsnakes have quite vibrant patterns. Some species, such as the scarlet kingsnake, Mexican milk snake, and red milk snake, have coloration and patterning that can cause them to be confused with the highly venomous coral snakes. One of the mnemonic rhymes to help people distinguish between coral snakes and their nonvenomous lookalikes in the United States is "red on black, a friend of Jack; red on yellow, kill a fellow".

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
