Cottus Aleuticus
The Coastrange sculpin (''Cottus aleuticus'') is a freshwater sculpin of the genus '' Cottus''. They are commonly found near the ocean in western North America, namely Canada and the United States. It is also known as the Aleutian sculpin. Taxonomy While the name ''Uranidea microstoma'' has been used since 1880, it is unclear whether or not it corresponds to the Coastrange sculpin. The species was first officially described by Charles Henry Gilbert in 1896 from specimens he collected in streams of Unalaska island the year before. ''Cottus protrusus'' was described in 1933, but it has since been found to be a synonym. Description The Coastrange sculpin can be distinguished from other species due to several unique traits. It only has one pore under its chin, no palatine teeth, and no distinct gap between the two dorsal fins. Adults can grow to be as long as 17 cm, although their average length is only 6 cm. Their maximum reported life span is 8 years. Breeding female Co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Morro Bay
Morro Bay (''Morro'', Spanish for "Hill") is a seaside city in San Luis Obispo County, California. Located on the Central Coast of California, the city population was 10,757 as of the 2020 census, up from 10,234 at the 2010 census. The town overlooks Morro Bay, a natural embayment with an all-weather small craft commercial and recreational harbor. History The prehistory of Morro Bay relates to Chumash settlement, particularly near the mouth of Morro Creek. At least as early as the Millingstone Horizon thousands of years before present, there was an extensive settlement along the banks and terraces above Morro Creek. A tribal site on present-day Morro Bay was named ''tsɨtqawɨ'', Obispeño for "Place of the Dogs". The first European land exploration of Alta California, the Spanish Portolá expedition, came down Los Osos Valley and camped near today's Morro Bay on September 8, 1769. Franciscan missionary and expedition member Juan Crespí noted in his diary that "we saw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
British Columbia
British Columbia (commonly abbreviated as BC) is the westernmost Provinces and territories of Canada, province of Canada, situated between the Pacific Ocean and the Rocky Mountains.

Three-spined Stickleback
The three-spined stickleback (''Gasterosteus aculeatus'') is a fish native to most inland and coastal waters north of 30°N. It has long been a subject of scientific study for many reasons. It shows great morphological variation throughout its range, ideal for questions about evolution and population genetics. Many populations are anadromous (they live in seawater but breed in fresh or brackish water) and very tolerant of changes in salinity, a subject of interest to physiologists. It displays elaborate breeding behavior (defending a territory, building a nest, taking care of the eggs and fry) and it can be social (living in shoals outside the breeding season) making it a popular subject of inquiry in fish ethology and behavioral ecology. Its antipredator adaptations, host-parasite interactions, sensory physiology, reproductive physiology, and endocrinology have also been much studied. Facilitating these studies is the fact that the three-spined stickleback is easy to find in na ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prickly Sculpin
''Cottus asper'' is a species of fish in the sculpin family known by the common name prickly sculpin. It is native to the river drainages of the Pacific Slope of North America from Seward, Alaska south to the Ventura River of Southern California.

Sympatry
In biology, two related species or populations are considered sympatric when they exist in the same geographic area and thus frequently encounter one another. An initially interbreeding population that splits into two or more distinct species sharing a common range exemplifies sympatric speciation. Such speciation may be a product of reproductive isolation – which prevents hybrid offspring from being viable or able to reproduce, thereby reducing gene flow – that results in genetic divergence. Sympatric speciation may, but need not, arise through secondary contact, which refers to speciation or divergence in allopatry followed by range expansions leading to an area of sympatry. Sympatric species or taxa in secondary contact may or may not interbreed. Types of populations Four main types of population pairs exist in nature. Sympatric populations (or species) contrast with parapatric populations, which contact one another in adjacent but not shared ranges and do n ...

Washington (state)
Washington (), officially the State of Washington, is a state in the Pacific Northwest region of the Western United States. Named for George Washington—the first U.S. president—the state was formed from the western part of the Washington Territory, which was ceded by the British Empire in 1846, by the Oregon Treaty in the settlement of the Oregon boundary dispute. The state is bordered on the west by the Pacific Ocean, Oregon to the south, Idaho to the east, and the Canadian province of British Columbia to the north. It was admitted to the Union as the 42nd state in 1889. Olympia is the state capital; the state's largest city is Seattle. Washington is often referred to as Washington state to distinguish it from the nation's capital, Washington, D.C. Washington is the 18th-largest state, with an area of , and the 13th-most populous state, with more than 7.7 million people. The majority of Washington's residents live in the Seattle metropolitan area, the center o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Washington
Lake Washington is a large freshwater lake adjacent to the city of Seattle. It is the largest lake in King County and the second largest natural lake in the state of Washington, after Lake Chelan. It borders the cities of Seattle on the west, Bellevue and Kirkland on the east, Renton on the south and Kenmore on the north, and encloses Mercer Island. The lake is fed by the Sammamish River at its north end and the Cedar River at its south. Lake Washington received its present name in 1854 after Thomas Mercer suggested it be named after George Washington, as the new Washington Territory had been named the year before. Earlier names for the lake include the Duwamish name ''Xacuabš'' (Lushootseed: literally "''xacu''" ''great-amount-of-water + "abš" people''), which referred to peoples who stayed along the coastline of Lake Washington, as well as Lake Geneva by Isaac N. Ebey; Lake Duwamish in railroad surveys under Governor Isaac Stevens; At-sar-kal in a map sketched ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Alaska
Alaska ( ; russian: Аляска, Alyaska; ale, Alax̂sxax̂; ; ems, Alas'kaaq; Yup'ik: ''Alaskaq''; tli, Anáaski) is a state located in the Western United States on the northwest extremity of North America. A semi-exclave of the U.S., it borders the Canadian province of British Columbia and the Yukon territory to the east; it also shares a maritime border with the Russian Federation's Chukotka Autonomous Okrug to the west, just across the Bering Strait.

Aleutian Islands
The Aleutian Islands ( ; ; ale, Unangam Tanangin, "land of the Aleuts"; possibly from the Chukchi ''aliat'', or "island")—also called the Aleut Islands, Aleutic Islands, or, before 1867, the Catherine Archipelago—are a chain of 14 main, larger volcanic islands and 55 smaller ones. Most of the Aleutian Islands belong to the U.S. state of Alaska, with the archipelago encompassing the Aleutians West Census Area and the Aleutians East Borough. The Commander Islands, located further to the west, belong to the Russian federal subject of Kamchatka Krai, of the Russian Far East. The islands form part of the Aleutian Arc of the Northern Pacific Ocean, and occupy a land area of 6,821 sq mi (17,666 km2) that extends westward roughly from the Alaskan Peninsula mainland, in the direction of the Kamchatka Peninsula; the archipelago acts as a border between the Bering Sea to the north and the Pacific Ocean to the south.
