Uta Stansburiana
The common side-blotched lizard (''Uta stansburiana'') is a species of side-blotched lizard in the family Phrynosomatidae. The species is native to dry regions of the western United States and northern Mexico. It is notable for having a unique form of polymorphism wherein each of the three different male morphs utilizes a different strategy in acquiring mates. The three morphs compete against each other following a pattern of rock paper scissors, where one morph has advantages over another but is outcompeted by the third. Etymology The specific epithet, ''stansburiana'', is in honor of Captain Howard Stansbury of the US Corps of Topographical Engineers, who collected the first specimens while leading the 1849-1851 expedition to explore and survey the Great Salt Lake of Utah. Taxonomy The systematics and taxonomy of the widespread and variable lizards of the genus '' Uta'' is much disputed. Countless forms and morphs have been described as subspecies or even distinct species. * ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spencer Fullerton Baird

He was dedicated to expanding the natural history collections of the Smithsonian which he increased from 6,000 specimens in 1850 to over 2 million by the time of his death. He published over 1,000 works during his lifetime. Early life and education Spencer Fullerton Baird was born in Reading, Pennsylvania in 1823.

Taxonomy (biology)
In biology, taxonomy () is the scientific study of naming, defining ( circumscribing) and classifying groups of biological organisms based on shared characteristics. Organisms are grouped into taxa (singular: taxon) and these groups are given a taxonomic rank; groups of a given rank can be aggregated to form a more inclusive group of higher rank, thus creating a taxonomic hierarchy. The principal ranks in modern use are domain, kingdom, phylum (''division'' is sometimes used in botany in place of ''phylum''), class, order, family, genus, and species. The Swedish botanist Carl Linnaeus is regarded as the founder of the current system of taxonomy, as he developed a ranked system known as Linnaean taxonomy for categorizing organisms and binomial nomenclature for naming organisms. With advances in the theory, data and analytical technology of biological systematics, the Linnaean system has transformed into a system of modern biological classification intended to reflect the evolu ...

Angel De La Guarda Side-blotched Lizard
In various theistic religious traditions an angel is a supernatural spiritual being who serves God. Abrahamic religions often depict angels as benevolent celestial intermediaries between God (or Heaven) and humanity. Other roles include protectors and guides for humans, and servants of God. Abrahamic religions describe angelic hierarchies, which vary by religion and sect. Some angels have specific names (such as Gabriel or Michael) or titles (such as seraph or archangel). Those expelled from Heaven are called fallen angels, distinct from the heavenly host. Angels in art are usually shaped like humans of extraordinary beauty. They are often identified in Christian artwork with bird wings, halos, and divine light. Etymology The word ''angel'' arrives in modern English from Old English ''engel'' (with a hard ''g'') and the Old French ''angele''. Both of these derive from Late Latin ''angelus'', which in turn was borrowed from Late Greek ''angelos'' (literally "messenge ...
