Sistrurus Catenatus
The eastern massasauga (''Sistrurus catenatus'') is a rattlesnake species found in central and eastern North America from southern Ontario in Canada and throughout the Midwestern and Eastern United States. Like all rattlesnakes, it is a pit viper and is venomous; it is the only species of venomous snake in Ontario. Taxonomy Three subspecies were recognized for more than a century, although research published in 2011 elevated two subspecies ''Sistrurus catenatus catenatus'' and ''Sistrurus catenatus tergeminus'', to full species: the eastern massasauga (''Sistrurus catenatus'') and the western massasauga (''Sistrurus tergeminus''). The status of the third subspecies was somewhat unresolved and it is tentatively recognized as the desert massasauga (''Sistrurus tergeminus edwardsii'') by some,Powell, Robert, Roger Conant, and Joseph T.

Rattlesnake
Rattlesnakes are venomous snakes that form the genus, genera ''Crotalus'' and ''Sistrurus'' of the subfamily Crotalinae (the pit vipers). All rattlesnakes are vipers. Rattlesnakes are predators that live in a wide array of habitats, hunting small animals such as birds and rodents. Rattlesnakes receive their name from the #Rattle, rattle located at the end of their tails, which makes a loud rattling noise when tail vibration, vibrated that deters predators. Rattlesnakes are the leading contributor to snakebite injuries in North America, but rarely bite unless provoked or threatened; if treated promptly, the bites are seldom fatal. The 36 known List of rattlesnake species and subspecies, species of rattlesnakes have between 65 and 70 subspecies, all native to the Americas, ranging from central Argentina to southern Canada. The largest rattlesnake, the Eastern diamondback rattlesnake, eastern diamondback, can measure up to in length. Rattlesnakes are preyed upon by hawks, wease ...

They are distinguished by the presence of a heat-sensing pit organ located between the eye and the nostril on both sides of the head. Currently, 23 genera and 155 species are recognized: These are also the only viperids found in the Americas. The groups of snakes represented here include rattlesnakes, lanceheads, and Asian pit vipers. The type genus for this subfamily is '' Crotalus'', of which the type species is the timber rattlesnake, ''C. horridus''.

Greek Language
Greek (, ; , ) is an Indo-European languages, Indo-European language, constituting an independent Hellenic languages, Hellenic branch within the Indo-European language family. It is native to Greece, Cyprus, Italy (in Calabria and Salento), southern Albania, and other regions of the Balkans, Caucasus, the Black Sea coast, Asia Minor, and the Eastern Mediterranean. It has the list of languages by first written accounts, longest documented history of any Indo-European language, spanning at least 3,400 years of written records. Its writing system is the Greek alphabet, which has been used for approximately 2,800 years; previously, Greek was recorded in writing systems such as Linear B and the Cypriot syllabary. The Greek language holds a very important place in the history of the Western world. Beginning with the epics of Homer, ancient Greek literature includes many works of lasting importance in the European canon. Greek is also the language in which many of the foundational texts ...

Sistrum
A sistrum (plural: sistra or (in Latin) sīstra; from the Greek ''seistron'' of the same meaning; literally "that which is being shaken", from ''seiein'', "to shake") is a musical instrument of the percussion family, a form of rattle, used most notably by the ancient Egyptians. It consists of a handle and a U-shaped metal frame, made of brass or bronze and ranging from in width. The frame supports sliding metal cross-bars, which may hold metal rings. When shaken, the small rings or loops of thin metal on its movable crossbars produce a sound that can vary from a soft clank to a loud jangling. Its name in the ancient Egyptian language was ''sekhem'' ''(sḫm)'' or ''sesheshet'' ''(sššt)'' because of the sound it made when it rattled. The ancient Egyptian sistrum had important associations with religious and ritualistic practices concerning various musical and joyful deities. A ''sekhem'' is the simpler, hoop-like sistrum, while a ''sesheshet'' (an onomatopoeic word) is the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species
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. It is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour, or ecological niche. In addition, palaeontologists 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. About 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomen". The first part of a binomen is the name of a genus to which the species belongs. The second part is called the specific name (zoology), specific name or the specific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scale (zoology)
In zoology, a scale (; ) is a small rigid plate (animal anatomy), plate made out of keratin that grows out of Vertebrate animals' skin to provide protection. In lepidopterans (butterflies and moths), scales are plates on the surface of the insect wing, made out of chitin instead of keratin, and provide coloration. Scales are quite common and have evolved multiple times through convergent evolution, with varying structure and function. Scales are generally classified as part of an organism's integumentary system. There are various types of scales according to the shape and class (biology), class of an animal. Fish scales Fish scales are skin, dermally derived, specifically in the mesoderm. This fact distinguishes them from reptile scales paleontologically. Genetically, the same genes involved in tooth and hair development in mammals are also involved in scale development.

Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...
