Siren (genus)
''Siren'' is a genus of aquatic salamanders of the family Sirenidae. The genus consists of five living species, along with one Extinction, extinct species from the Eocene, Eocene Epoch and three from the Miocene. The living species have elongated, eel-like bodies, with two small Vestigiality, vestigial Forelimb, fore legs. Siren intermedia, the lesser siren, has been seen as both a colonizer and a dominant species, in a single community, at two different succession stages. In Texas, during the 1970s, the species was found to have removed at least 283 individuals from a beaver pond, over a four year period. Species Extant species, Extant (living) species include: *''Siren intermedia'' species:Daniel H. Barnes, Barnes, 1826 – lesser siren *''Siren lacertina'' Carl Linnaeus, Linnaeus, 1766 – greater siren *''Siren nettingi'' species:Coleman Jett Goin, Goin, 1942 – Lesser siren, western siren *''Siren reticulata'' species:Sean P.

Siren Intermedia
The lesser siren (''Siren intermedia'') is a species of aquatic salamander native to the eastern United States and northern Mexico. They are referred to by numerous common names, including two-legged eel, dwarf siren, and mud eel. The specific epithet ''intermedia'' denotes their intermediate size, between the greater siren, ''Siren lacertina'', and the dwarf sirens, ''Pseudobranchus'' species. Description Lesser sirens have elongated bodies possessing only two limbs, a pair of four-toed legs located behind the base of the head, and range in length from 7 to 27 inches (17 – 69 cm). Unlike greater sirens, lesser sirens have less than 35 costal grooves. Juvenile specimens have red to yellow banding on their heads and stripes running along the main length of the body, although these stripes are absent in ''Siren intermedia''. Adults have plainer coloration; the dorsal side is typically olive green to blue-gray or black, while the ventral is usually light grey. Spotted patter ...

Greater Siren
The greater siren (''Siren lacertina'') is an amphibian and one of the five members of the genus '' Siren''. The largest of the sirens and one of the largest amphibians in North America, the greater siren resides in the coastal plains of the southeastern United States. Description The greater siren is the third longest salamander in the Western Hemisphere. ''S. lacertina'' is paedomorphic, as are all sirens. They lack hindlimbs as well as a pelvic girdle, and have external gills all throughout their lives along with small lungs. They lack eyelids, and have an unfused pectoral girdle. Greater sirens measure around in length upon hatching and then grow to lengths ranging from . Weight can range from . Coloration varies throughout their range, but they are generally an olive or gray color with small yellow or green dots on their sides. They have about 36 to 40 costal grooves between their armpits and their cloaca. Younger sirens also have a light stripe along their sides, which fa ...

Dwarf Siren
Dwarf sirens are eel-like salamanders of the genus ''Pseudobranchus''. Dwarf sirens possess external gills throughout adulthood and lack hind legs, and can be distinguished from members of the genus '' Siren'' in that dwarf sirens have three toes on each foot rather than four. Whereas sirens have three gill slits, dwarf sirens keep just a single slit. Like sirens, dwarf sirens are restricted to the Southeastern United States. Species The genus ''Pseudobranchus'' consists of the following extant species: * Southern dwarf siren (''P. axanthus'') **Narrow-striped dwarf siren (''P. a. axanthus'') **Everglades dwarf siren (''P. a. belli'') * Northern dwarf siren (''P. striatus'') **Broad-striped dwarf siren (''P. s. striatus'') **Gulf Hammock dwarf siren (''P. s. lustricolus'') **Slender dwarf siren (''P. s. spheniscus'') There are also two extinct species known from fossil evidence: * †''Pseudobranchus vetustus'' (Miocene to Pliocene of Florida) * †''Pseudobranchus robus ...

Walter Auffenberg
Walter Auffenberg ( – ) was an American biologist who spent almost 40 years in field research, studying reptile and amphibian paleontology and the systematics and biology of numerous reptile species, including alligators and Komodo dragons. Early life Auffenberg was born in Detroit, Michigan, in 1928. After graduating high school, he relocated to DeLand, Florida, to work on two small citrus groves owned by his parents. Shortly after, he enlisted in the US Navy and trained as a Hospital Corpsman in Corpus Christi, Texas. Upon his discharge he returned to Florida and attended Stetson University in DeLand, receiving his Bachelor of Science in zoology in 1951. He moved to Gainesville, Florida, to obtain his advanced degrees at the University of Florida. Academic life Auffenberg received his M.Sc. from the University of Florida in 1953 with his thesis A Study of Geographic Morphological Variation in the Blacksnake. He held a temporary position as Curator of Vertebrate Paleonto ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seepage Siren
The seepage siren (''Siren sphagnicola'') is a species of aquatic salamander in the family Sirenidae. It was described as a new species in 2023 by Fedler et al. The species is notable for being the smallest described siren species and is distinguished by several unique morphological features. The discovery of ''Siren sphagnicola'' highlights the ongoing description of new species in the Gulf Coastal Plain The Gulf Coastal Plain extends around the Gulf of Mexico in the Southern United States and eastern Mexico. This coastal plain reaches from the Florida Panhandle, southwest Georgia (U.S. state), Georgia, the southern two-thirds of Alabama, over m ..., a global biodiversity hotspot. This discovery, along with others like the reticulated or leopard siren (''Siren reticulata'') described in 2018, underscores the importance of habitat protection and the need for further research to understand these species' roles in their ecosystems.

Reticulated Siren
The reticulated siren (''Siren reticulata''), also known as the leopard siren or colloquially as the leopard eel, is a species of aquatic salamander in the family Sirenidae. The species, which is endemic to the southeastern United States, was first formally described in 2018. This cryptic salamander is known only from three localities in southern Alabama and the Florida panhandle and is one of the largest animals in the United States to be newly described in the past 100 years. Description The reticulated siren is one of the largest species of extant (living) salamanders worldwide, reaching up to in total length, which rivals the hellbender of the Appalachian Mountains as both the largest amphibian in North America and the fourth largest salamander in the world. It has a greenish grey, eel-like body, large external gills, and two small front legs. The sides and belly are a lighter yellowish green. It has an average snout to vent length (SVL) of .

Crystal Kelehear
A crystal or crystalline solid is a solid material whose constituents (such as atoms, molecules, or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions. In addition, macroscopic single crystals are usually identifiable by their geometrical shape, consisting of flat faces with specific, characteristic orientations. The scientific study of crystals and crystal formation is known as crystallography. The process of crystal formation via mechanisms of crystal growth is called crystallization or solidification. The word ''crystal'' derives from the Ancient Greek word (), meaning both "ice" and "rock crystal", from (), "icy cold, frost". Examples of large crystals include snowflakes, diamonds, and table salt. Most inorganic solids are not crystals but polycrystals, i.e. many microscopic crystals fused together into a single solid. Polycrystals include most metals, rocks, ceramics, and ice. A third category of sol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
David A
David (; , "beloved one") was a king of ancient Israel and Judah and the third king of the United Monarchy, according to the Hebrew Bible and Old Testament. The Tel Dan stele, an Aramaic-inscribed stone erected by a king of Aram-Damascus in the late 9th/early 8th centuries BCE to commemorate a victory over two enemy kings, contains the phrase (), which is translated as " House of David" by most scholars. The Mesha Stele, erected by King Mesha of Moab in the 9th century BCE, may also refer to the "House of David", although this is disputed. According to Jewish works such as the '' Seder Olam Rabbah'', '' Seder Olam Zutta'', and '' Sefer ha-Qabbalah'' (all written over a thousand years later), David ascended the throne as the king of Judah in 885 BCE. Apart from this, all that is known of David comes from biblical literature, the historicity of which has been extensively challenged,Writing and Rewriting the Story of Solomon in Ancient Israel; by Isaac Kalimi; page 3 ...
