Townsend's Mole
The Townsend's mole (''Scapanus townsendii'') is a fossorial mammal in the family Talpidae, and is the largest North American mole. It was named after the American naturalist John Kirk Townsend. The name was selected at the request of Thomas Nuttall as a patronym to honor Townsend's contribution. Distribution and habitat It is found in open lowland and wooded areas with moist soils along the Pacific coast from southwestern British Columbia to northwestern California. This animal's total range in Canada is estimated to be 20 km² (). Conservation Townsend's mole is classified as Least Concern by the IUCN; however, in Canada it is considered an endangered species. Description It has velvety black fur, a pointed snout and a short, thick, a tail with barely any hair. It is about in length including a tail, and weighs about . Its front paws are broad and spade-shaped, specialized for digging; the rear paws are smaller. It has 44 teeth. Its ears are not visible and it has small ey ...

John Bachman
John Bachman (February 4, 1790 – February 24, 1874) was an American Lutheran minister, social activist and naturalist who collaborated with John James Audubon to produce ''Viviparous Quadrupeds of North America'' and whose writings, particularly ''Unity of the Human Race'', were influential in the development of the theory of evolution. He was married to the painter Maria Martin. Several species of animals are named in his honor. Life Bachman served the same Charleston, South Carolina church as pastor for 56 years but still found time to conduct natural history studies that caught the attention of noted bird artist John James Audubon and eminent scientists in England, Europe, and beyond. He was a proponent of secular and religious education and helped found Newberry College and the Lutheran Theological Southern Seminary, as well as the South Carolina Lutheran Synod. He was elected an Associate Fellow of the American Academy of Arts and Sciences in 1845. Bachman was a soci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Scapanus
''Scapanus'' is a genus of moles in the family Talpidae. They live in North America from west of the Rockies south to Baja California del Norte, and north to British Columbia, wherever conditions permit a mole population; that is to say, apart from the most sandy, rocky, or developed places. As they are one genus, they are very closely related, but as species, they rarely if ever interbreed successfully. It contains the following living species: * Mexican mole (''S. anthonyi'') * Northern broad-footed mole (''S. latimanus'') * Southern broad-footed mole (''S. occultus'') * Coast mole (''S. orarius'') * Townsend's mole (''S. townsendii'') In addition, there are several extinct species known from fossils. *''Scapanus hagermanensis'' ( Mid Blancan stage, Idaho) *''Scapanus malatinus'' ( Blancan- Quaternary, California). *''Scapanus proceridens'' (Miocene, Oregon and Idaho) *''Scapanus shultzi'' (Miocene, California and Oregon) Distribution Townsend's mole is primarily a Cal ...

Invertebrate
Invertebrates are a paraphyletic group of animals that neither possess nor develop a vertebral column (commonly known as a ''backbone'' or ''spine''), derived from the notochord. This is a grouping including all animals apart from the chordate subphylum Vertebrata. Familiar examples of invertebrates include arthropods, mollusks, annelids, echinoderms and cnidarians. The majority of animal species are invertebrates; one estimate puts the figure at 97%. Many invertebrate taxa have a greater number and variety of species than the entire subphylum of Vertebrata. Invertebrates vary widely in size, from 50 μm (0.002 in) rotifers to the 9–10 m (30–33 ft) colossal squid. Some so-called invertebrates, such as the Tunicata and Cephalochordata, are more closely related to vertebrates than to other invertebrates. This makes the invertebrates paraphyletic, so the term has little meaning in taxonomy. Etymology The word "invertebrate" comes from the Latin word ''vertebra'', whi ...

Earthworm
An earthworm is a terrestrial invertebrate that belongs to the phylum Annelida. They exhibit a tube-within-a-tube body plan; they are externally segmented with corresponding internal segmentation; and they usually have setae on all segments. They occur worldwide where soil, water, and temperature allow. Earthworms are commonly found in soil, eating a wide variety of organic matter. This organic matter includes plant matter, living protozoa, rotifers, nematodes, bacteria, fungi, and other microorganisms. An earthworm's digestive system runs the length of its body. An earthworm respires (breathes) through its skin. It has a double transport system made of coelomic fluid that moves within the fluid-filled coelom and a simple, closed circulatory system. It has a central and peripheral nervous system. Its central nervous system consists of two ganglia above the mouth, one on either side, connected to a nerve running along its length to motor neurons and sensory cells in each s ...

Burrow
An Eastern chipmunk at the entrance of its burrow A burrow is a hole or tunnel excavated into the ground by an animal to construct a space suitable for habitation or temporary refuge, or as a byproduct of locomotion. Burrows provide a form of shelter against predation and exposure to the elements, and can be found in nearly every biome and among various biological interactions. Many animal species are known to form burrows. These species range from small invertebrates, such as the ''Corophium arenarium'', to very large vertebrate species such as the polar bear. Burrows can be constructed into a wide variety of substrates and can range in complexity from a simple tube a few centimeters long to a complex network of interconnecting tunnels and chambers hundreds or thousands of meters in total length; an example of the latter level of complexity, a well-developed burrow, would be a rabbit warren. Vertebrate burrows A large variety of vertebrates construct or use burrows in many t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coast Mole
The coast mole or Pacific mole (''Scapanus orarius'') is a medium-sized North American mole found in forested and open areas with moist soils along the Pacific coast from southwestern British Columbia to northwestern California. Taxonomy Two subspecies are recognized: the nominate, ''S. o. orarius'', and Scheffer's coast mole, ''S. o. schefferi''. The nominate has a shorter skull and less enlarged maxillary region. The patterns of teeth shearing on dirt and earthworms (their main diet) set both subspecies apart from similar species. Description The coast mole is generally less than 200 mm long, with the tail being one-fourth of its total length. The fur is uniformly black. The skull is relatively narrow and long, with a sublacrimal-maxillary ridge that is underdeveloped. Teeth are uncrowned and evenly spaced. Distribution and habitat The coast mole has a disjunct distribution, occurring from the western end of British Columbia, Canada through the western regions of Ore ...

Canada
Canada is a country in North America. Its ten provinces and three territories extend from the Atlantic Ocean to the Pacific Ocean and northward into the Arctic Ocean, covering over , making it the world's second-largest country by total area. Its southern and western border with the United States, stretching , is the world's longest binational land border. Canada's capital is Ottawa, and its three largest metropolitan areas are Toronto, Montreal, and Vancouver. Indigenous peoples have continuously inhabited what is now Canada for thousands of years. Beginning in the 16th century, British and French expeditions explored and later settled along the Atlantic coast. As a consequence of various armed conflicts, France ceded nearly all of its colonies in North America in 1763. In 1867, with the union of three British North American colonies through Confederation, Canada was formed as a federal dominion of four provinces. This began an accretion of provinces an ...

British Columbia
British Columbia (commonly abbreviated as BC) is the westernmost province of Canada, situated between the Pacific Ocean and the Rocky Mountains. It has a diverse geography, with rugged landscapes that include rocky coastlines, sandy beaches, forests, lakes, mountains, inland deserts and grassy plains, and borders the province of Alberta to the east and the Yukon and Northwest Territories to the north. With an estimated population of 5.3million as of 2022, it is Canada's third-most populous province. The capital of British Columbia is Victoria and its largest city is Vancouver. Vancouver is the third-largest metropolitan area in Canada; the 2021 census recorded 2.6million people in Metro Vancouver. The first known human inhabitants of the area settled in British Columbia at least 10,000 years ago. Such groups include the Coast Salish, Tsilhqotʼin, and Haida peoples, among many others. One of the earliest British settlements in the area was Fort Victoria, established ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fossorial
A fossorial () animal is one adapted to digging which lives primarily, but not solely, underground. Some examples are badgers, naked mole-rats, clams, meerkats, and mole salamanders, as well as many beetles, wasps, and bees. Prehistoric evidence The physical adaptation of fossoriality is widely accepted as being widespread among many prehistoric phyla and taxa, such as bacteria and early eukaryotes. Furthermore, fossoriality has evolved independently multiple times, even within a single family. Fossorial animals appeared simultaneously with the colonization of land by arthropods in the late Ordovician period (over 440 million years ago). Other notable early burrowers include ''Eocaecilia'' and possibly ''Dinilysia''. The oldest example of burrowing in synapsids, the lineage which includes modern mammals and their ancestors, is a cynodont, ''Thrinaxodon liorhinus'', found in the Karoo of South Africa, estimated to be 251 million years old. Evidence shows that this ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
