Clear Lake Splittail
The Clear Lake splittail (''Pogonichthys ciscoides'') was endemic to California's Clear Lake and its tributaries until its numbers severely declined due to competition from the introduced bluegill and alterations to the flow of inlet streams. In greatly reduced numbers, the Clear Lake Splittail barely persisted until the 1967 introduction to surrounding lakes of the inland silverside The inland silverside (''Menidia beryllina'') is a neotropical silverside native to eastern North America, and introduced into California. It is a fish of estuaries and freshwater environments. Inland silversides are quite elongate even for silv ... as an experiment by the Department of Fish & Game. A fisherman supposedly introduced the silverside via bait bucket into Clear Lake. This dealt the final blow to the Clear Lake splittail, which had similar feeding habits. All of the splittails were taken by fishermen or have been eaten by catfish and large mouth bass. No Clear Lake splittails have been ...

Clear Lake (California)
Clear Lake (Pomo: ''Lypoyomi'') is a natural freshwater lake in Lake County in the U.S. state of California, north of Napa County and San Francisco. It is the largest natural freshwater lake wholly within the state, with of surface area. At an age of 2.5 million years, it is the oldest lake in North America. It is the latest lake to occupy a site with a history of lakes stretching back at least 2,500,000 years. Clear Lake supports large populations of largemouth bass, crappie, bluegill, carp and catfish. Two-thirds of the fish caught in Clear Lake are largemouth bass, with a record of . In addition to fish, there is abundant wildlife within the Clear Lake basin. There are year-round populations of ducks, pelicans, grebes, blue herons, egrets, osprey, and bald eagles, and the basin supports sizable populations of deer, bear, mountain lion, raccoon and other animals. The expansive, warm water of Clear Lake makes it popular for watersports, such as swimming, water skiing, wak ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inland Silverside
The inland silverside (''Menidia beryllina'') is a neotropical silverside native to eastern North America, and introduced into California. It is a fish of estuaries and freshwater environments. Inland silversides are quite elongate even for silverside, with lengths six to seven times depth. They have large eyes, a considerably upturned mouth, and a head noticeably flattened on top. Of the two widely separated dorsal fins, the anterior fin is small and has four to five weak spines, while the posterior fin is larger, with one spine and eight or nine rays. The lengthy anal fin is somewhat sickle-shaped, has one spine and 16 to 18 rays. As befits the name, they are silvery on the sides; the back is somewhat yellowish, and the underside is a translucent greenish. These are small fish, with 15 cm recorded, but most adults 10 cm or less. They primarily feed on zooplankton, moving in enormous schools capable of depleting populations of the small arthropods and crustaceans they ...

Pogonichthys
The splittails are a genus ''Pogonichthys'' of cyprinid fish, consisting of two species native to western North America. The common name is inspired by the distinctive appearance of the tail fin, in which the upper lobe is distinctly larger. Of the two species, only the Sacramento splittail survives; the Clear Lake splittail became extinct in the mid-1970s. Species * †''Pogonichthys ciscoides'' Hopkirk, 1974 (Clear Lake splittail) * ''Pogonichthys macrolepidotus The splittail (''Pogonichthys macrolepidotus''), also called Sacramento splittail, is a cyprinid fish native to the low-elevation waters of the Central Valley in California.

Endemic Fauna Of California
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fish Described In 1974
Fish are aquatic, craniate, gill-bearing animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Approximately 95% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with around 99% of those being teleosts. The earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Cambrian period. Although they lacked a true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts. Fish would continue to evolve through the Paleozoic era, diversifying into a wide variety of forms. Many fish of the Paleozoic developed external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) became formidable marine predators rather than just the prey of arthropods. Most f ...

Extinct Animals Of The United States
Extinction is the termination of a kind of organism or of a group of kinds (taxon), usually a species. The moment of extinction is generally considered to be the death of the last individual of the species, although the capacity to breed and recover may have been lost before this point. Because a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the fossil record) after a period of apparent absence. More than 99% of all species that ever lived on Earth, amounting to over five billion species, are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryote globally, and possibly many times more if microorganisms, like bacteria, are included. Notable extinct animal species include non-avian dinosaurs, saber-toothed cats, dodos, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fish Of North America Becoming Extinct Since 1500
Fish are Aquatic animal, aquatic, craniate, gill-bearing animals that lack Limb (anatomy), limbs with Digit (anatomy), digits. Included in this definition are the living hagfish, lampreys, and Chondrichthyes, cartilaginous and bony fish as well as various extinct related groups. Approximately 95% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with around 99% of those being teleosts. The earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Cambrian period. Although they lacked a vertebrate, true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts. Fish would continue to evolve through the Paleozoic era, diversifying into a wide variety of forms. Many fish of the Paleozoic developed placodermi, external armor that protected them from predators.
