American Bullfrog
The American bullfrog (''Lithobates catesbeianus''), often simply known as the bullfrog in Canada and the United States, is a large true frog native to eastern North America. It typically inhabits large permanent water bodies such as swamps, ponds, and lakes. Bullfrogs can also be found in man made habitats such as pools, koi ponds, canals, ditches and culverts. The bullfrog gets its name from the sound the male makes during the breeding season, which sounds similar to a bull bellowing. The bullfrog is large and is commonly eaten throughout its range, especially in the southern United States where they are plentiful. Their presence as a food source has led to bullfrogs being distributed around the world outside of their native range. Bullfrogs have been introduced into the Western United States, South America, Western Europe, China, Japan, and southeast Asia. In these places they are invasive species due to their voracious appetite and the large number of eggs they produce, havi ...

Introduced Species
An introduced species, alien species, exotic species, adventive species, immigrant species, foreign species, non-indigenous species, or non-native species is a species living outside its native distributional range, but which has arrived there by human activity, directly or indirectly, and either deliberately or accidentally. Non-native species can have various effects on the local ecosystem. Introduced species that become established and spread beyond the place of introduction are considered naturalized. The process of human-caused introduction is distinguished from biological colonization, in which species spread to new areas through "natural" (non-human) means such as storms and rafting. The Latin expression neobiota captures the characteristic that these species are ''new'' biota to their environment in terms of established biological network (e.g. food web) relationships. Neobiota can further be divided into neozoa (also: neozoons, sing. neozoon, i.e. animals) and neophyt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Unkenreflex
Unkenreflex – interchangeably referred to as unken reflex (''Unke'' is the German word for the genus of fire-bellied toads) – is a defensive posture adopted by several branches of the amphibian class – including salamanders, toads, and certain species of frogs. Implemented most often in the face of an imminent attack by a predator, unkenreflex is characterized by the subject’s contortion or arching of its body to reveal previously hidden bright colors of the ventral side, tail, or inner limb; the subject remains immobile while in unkenreflex. During the course of unkenreflex, the amphibian in question releases bufotoxins from its parotid glands, tenses its entire body, and swallows air to bloat itself in an attempt to look larger. These secretions, along with the Aposematism, aposematic coloring common among the amphibians which display unkenreflex, serve as a warning to nearby predators that the amphibian may be poisonous. Not all amphibians which display unkenreflexes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
California Newt
The California newt or orange-bellied newt (''Taricha torosa''), is a species of newt endemic to California, in the Western United States. Its adult length can range from . Its skin produces the potent toxin tetrodotoxin. Subspecies ''Taricha torosa'' was divided into two subspecies until 2007, when it was determined that the Sierra and coastal populations represent distinct evolutionary lineages. The former subspecies ''Taricha torosa sierrae'' was elevated to full species level and it is now known as ''Taricha sierrae'', the Sierra newt. ''Taricha torosa torosa'' has been retired and now all coastal populations are simply known as ''Taricha torosa'', the California newt. Range and habitat California newts reside in the coastal counties of California and in the southern Sierra Nevada and occupy a diverse array of habitats found near the small ponds and creeks where they breed, including woodlands and chaparral. Description The California newt has warty, slate-gray skin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

San Francisco Garter Snake
The San Francisco garter snake (''Thamnophis sirtalis tetrataenia'') is a slender multi-colored subspecies of the common garter snake. Designated as an endangered subspecies since the year 1967, it is endemic to San Mateo County and the extreme northern part of coastal Santa Cruz County in California. Some researchers estimate that there are only 1,000 to 2,000 adult snakes of the subspecies ''T. s. tetrataenia'' remaining. However, the full extent of the snakes' habitat has not been fully documented, and many snakes may utilize creeks and other waterways that are currently unexplored. This garter snake prefers wet and marshy areas, and because of its elusive nature, it is difficult to see or capture. Geographic range The San Francisco garter snake, a subspecies of the common garter snake, is found in scattered wetland areas on the San Francisco Peninsula from approximately the northern boundary of San Mateo County south along the eastern and western bases of the Santa Cruz Mou ...
