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 patte ...

Siren Reticulata
The reticulated siren (''Siren reticulata''), also known commonly 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 .

Sirenoidea
Sirenidae, the sirens, are a family of neotenic aquatic salamanders. Family members have very small fore limbs and lack hind limbs altogether. In one species, the skeleton in their fore limbs is made of only cartilage. In contrast to most other salamanders, they have external gills bunched together on the neck in both larval and adult states. Sirens are found only in the Southeastern United States and northern Mexico. Although they are primarily carnivorous, they are the only salamanders observed eating plant material.Hill, R. L., Mendelson, J. R. & Stabile, J. L. 2015. Direct observation and review of herbivory in Sirenidae (Amphibia: Caudata). Southeastern Naturalist 14, N5-N9. Description Sirens are quite distinct from other salamanders, and in some classifications they form their own suborder, Sirenoidea, or as a completely distinct order (Meantes or Trachystomata). Genetic analysis variously places them as the sister to other Salamandroidea or as sister to all other salama ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dwarf Siren
Dwarf sirens are eel-like salamanders of the genus ''Pseudobranchus''. Dwarf sirens possess external gills throughout adulthood and lack hind legs. Dwarf sirens can be distinguished from members of the genus ''Siren'' in that dwarf sirens have three toes on each foot rather than four. 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 robustus'' (Pleistocene The Pleistocene ( , often referred to as ...

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 Paleontology ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
