Dendrocoelopsis alaskensis is a species of freshwater triclad in the family Dendrocoelidae. [1] It is found in the White Mountains in Alaska.
Though not explicitly stated in the original publication, the specific epithet is clearly derived from its type-locality, being found in the streams of Alaska's White Mountains. [2]
Dendrocoelopsis alaskensis has two auricles on its front. The head slightly narrows behind those auricles; the body widens in the middle and the back is a blunt point. Its body is all white. It has two eyes. [2]
Planarians (triclads) are free-living flatworms of the class Turbellaria, order Tricladida, which includes hundreds of species, found in freshwater, marine, and terrestrial habitats. Planarians are characterized by a three-branched intestine, including a single anterior and two posterior branches. Their body is populated by adult stem cells called neoblasts, which planarians use for regenerating missing body parts. Many species are able to regenerate any missing organ, which has made planarians a popular model in research of regeneration and stem cell biology. The genome sequences of several species are available, as are tools for molecular biology analysis.
Norton Sound is an inlet of the Bering Sea on the western coast of the U.S. state of Alaska, south of the Seward Peninsula. It is about 240 km (150 mi) long and 200 km (125 mi) wide. The Yukon River delta forms a portion of the south shore and water from the Yukon influences this body of water. It is ice-free from June to October.
Dugesia is a genus of dugesiid triclads that contains some common representatives of the class Turbellaria. These common flatworms are found in freshwater habitats of Africa, Eurasia, and Australia. Dugesia is best known to non-specialists because of its regeneration capacities.
