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 maxilla, they comprise the hard palate.
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.
Planorbidae, common name the ramshorn snails or ram's horn snails, is a family of air-breathing freshwater snails, aquatic pulmonate gastropod molluscs. Unlike most molluscs, the blood of ram's horn snails contains iron-based hemoglobin instead of copper-based hemocyanin. As a result, planorbids are able to breathe oxygen more efficiently than other molluscs. The presence of hemoglobin gives the body a reddish colour. This is especially apparent in albino animals.
The Sierra newt is a newt found west of the Sierra Nevada, from Shasta county to Tulare County, in California, Western North America.
Glossiphoniidae are a family of freshwater proboscis-bearing leeches. These leeches are generally flattened, and have a poorly defined anterior sucker. Most suck the blood of freshwater vertebrates like amphibians, crocodilians and aquatic turtles, but some feed on invertebrates like oligochaetes and freshwater snails instead. Although they prefer other hosts, blood-feeding species will opportunistically feed from humans.
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.
Cosmocercoides is a genus of nematode within the order Ascaridida. Nematodes within the genus Cosmocercoides have been found as parasites within the rough-skinned newt, Taricha granulosa. Cosmocercoides includes the following species:
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.
