In anatomy, the palatine bones are two irregular bones of the facial skeleton in many animal species, located above the uvula in the throat. Together with the maxillae, they comprise the hard palate.
Salamandridae is a family of salamanders consisting of true salamanders and newts. Salamandrids are distinguished from other salamanders by the lack of rib or costal grooves along the sides of their bodies and by their rough skin. Their skin is very granular because of the number of poison glands. They also lack nasolabial grooves. Most species of Salamandridae have moveable eyelids but lack lacrimal glands.
Corixidae is a family of aquatic insects in the order Hemiptera. They are found worldwide in virtually any freshwater habitat and a few species live in saline water. There are about 500 known species worldwide, in 55 genera, including the genus Sigara.
The Siskiyou Mountains salamander, also called the Siskiyou Mountain salamander, exists only in isolated locations along the Klamath River in northern California and southern Oregon. It is a close relative of the Del Norte salamander, and some herpetologists believe it may be a subspecies of that animal.
The genus Taricha consists of four species of highly toxic newts in the family Salamandridae. Their common name is Pacific newts, sometimes also western newts or roughskin newts. The four species within this genus are the California newt, the rough-skinned newt, the red-bellied newt, and the sierra newt, all of which are found on the Pacific coastal region from southern Alaska to southern California, with one species possibly ranging into northern Baja California, Mexico.
The rough-skinned newt or roughskin newt is a North American newt known for the strong toxin exuded from its skin.
The California newt or orange-bellied newt, is a species of newt endemic to California, in the Western United States. Its adult length can range from 5 to 8 in. Its skin produces the potent toxin tetrodotoxin.
The Sierra newt is a newt found west of the Sierra Nevada, from Shasta county to Tulare County, in California, Western North America.
Planorbella is a genus of freshwater air-breathing snails, aquatic pulmonate gastropod mollusks in the family Planorbidae, the ram's horn snails, or planorbids, which all have sinistral, or left-coiling, shells.
The Tulameen River is a tributary of the Similkameen River in the Canadian province of British Columbia. The Tulameen River is part of the Columbia River drainage basin, being a tributary of the Similkameen River, which flows into the Okanagan River, which flows into the Columbia River.
The Crater Lake newt or Mazama newt, Taricha granulosa mazamae, is a subspecies of the rough-skinned newt. Its type locality is Crater Lake, Oregon. Similar newts have been found in Alaska, but their identity is unclear.
A nuptial pad is a secondary sex characteristic present on some mature male frogs and salamanders. Triggered by androgen hormones, this breeding gland appears as a spiked epithelial swelling on the forearm and prepollex that aids with grip, which is used primarily by males to grasp females during amplexus. They can also be used in male–male combat in some species.
Megalobatrachonema is a nematode genus. Species of this genus are parasites of a number of amphibians including the rough-skinned newt.
Karotomorpha is a genus of parasites with a flagellum structure. This organism can infect a variety of higher life forms including a number of amphibians. For example, this genus is known to be a parasite of the rough-skinned newt, a widespread newt in the western USA.
Cephalouterina is a genus of trematodes within the family Lecithodendriidae under the order Plagiorchiida. Individuals of this genus are known to use amphibian hosts.
Cephalouterina decamptodoni is a species of trematodes within the family Lecithodendriidae under the order Plagiorchiida. This species is sometimes known to use amphibian hosts.
Tritrichomonas is a genus of single celled flagellated parasitic excavates, some of whose species are known to be pathogens of the bovine reproductive tract as well as the intestinal tract of felines.
Marion Lake is a subalpine lake located in Linn County of the U.S. state of Oregon. The lake is in central Oregon's Cascades within the Mount Jefferson Wilderness. The lake is approximately 300 acres (1.2 km2), at an elevation of 4,134 feet (1,260 m).
Perennibranchiate, in zoology, is the condition of an organism retaining branchae, or gills, through life. This condition is generally said of certain amphibia, such as the mudpuppy. The term is opposed to caducibranchiate. In some cases only a small proportion of a given amphibian population is perennibranchiate, but in other instances a preponderance of the individuals have an adult gill retention. For example, in the case of the Rough-skinned Newt in the Cascade Mountains populations, approximately ninety percent of the adult population is perennibranchiate.
The Bedded Range is a mountain range in the Hozameen Range subdivision of the Canadian Cascades, which are the extension of the Cascade Range into British Columbia, Canada. Located between the Coquihalla and Tulameen Rivers, the Bedded Range is a dioritic plug related to the Chilliwack batholith.
