Upogebia Pugettensis
''Upogebia pugettensis'', also known as the blue mud shrimp, is a species of mud lobster from the West Coast of North America. Description ''Upogebia pugettensis'' has an elongated and broad abdomen, including a well-developed tail fin (uropods). The shrimp measure up to 11 cm long in adulthood. Its snout ( rostrum) is hairy and includes 3 teeth. They eat detritus which they bring into their burrow using their pleopods. ''Upogebia pugettensis'' is the host of many parasites: '' Pseudopythina rugifera'', '' Phyllodurus abdominalis'', and '' Orthione griffenis''. Distribution ''Upogebia pugettensis'' is found from Valdez Narrows, Alaska, to Morro Bay, California. South of Morro Bay, '' U. macginitieorum'', a very similar species to ''U. pugettensis'', is found. Ecology ''Upogebia pugettensis'' lives in Y- or U-shaped burrows ( deep) that are located in inter-tidal mud flats. These shrimp can tolerate brackish water down to 10% seawater salinity. They usually live ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Upogebia Deltaura
''Upogebia deltaura'' is a species of mud lobster from the Atlantic Ocean and Mediterranean Sea. Description ''Upogebia deltaura'' is up to long, and is a dirty yellow colour, tinged with green, white or red. It is often confused with other species which it closely resembles, such as '' Upogebia stellata'', which has additional ocular spines and a narrower abdomen. The mouthparts are densely setose, which helps to filter particles out of the water. Distribution ''Upogebia deltaura'' is found in the eastern Atlantic from Sognefjord, Norway to Spain, and throughout the Mediterranean Sea as well as in the Black Sea. It may also extend as far as Togo, West Africa, but possible confusion with other taxa makes this difficult to assess. Ecology ''Upogebia deltaura'' lives in burrows at up to depth, and will make use of burrows dug by other animals. ''U. deltaura'' is the most abundant large crustacean and the deepest burrowing (up to ) large animal in Scottish maerl beds, and w ...

Mudflat
Mudflats or mud flats, also known as tidal flats or, in Ireland, slob or slobs, are coastal wetlands that form in intertidal areas where sediments have been deposited by tides or rivers. A global analysis published in 2019 suggested that tidal flat ecosystems are as extensive globally as mangroves, covering at least of the Earth's surface. / They are found in sheltered areas such as bays, bayous, lagoons, and estuaries; they are also seen in freshwater lakes and salty lakes (or inland seas) alike, wherein many rivers and creeks end. Mudflats may be viewed geologically as exposed layers of bay mud, resulting from deposition of estuarine silts, clays and aquatic animal detritus. Most of the sediment within a mudflat is within the intertidal zone, and thus the flat is submerged and exposed approximately twice daily. A recent global remote sensing analysis estimated that approximately 50% of the global extent of tidal flats occurs within eight countries (Indonesia, China, Austral ...

Crustaceans Of The Pacific Ocean
Crustaceans (Crustacea, ) form a large, diverse arthropod taxon which includes such animals as decapods, seed shrimp, branchiopods, fish lice, krill, remipedes, isopods, barnacles, copepods, amphipods and mantis shrimp. The crustacean group can be treated as a subphylum under the clade Mandibulata. It is now well accepted that the hexapods emerged deep in the Crustacean group, with the completed group referred to as Pancrustacea. Some crustaceans (Remipedia, Cephalocarida, Branchiopoda) are more closely related to insects and the other hexapods than they are to certain other crustaceans. The 67,000 described species range in size from '' Stygotantulus stocki'' at , to the Japanese spider crab with a leg span of up to and a mass of . Like other arthropods, crustaceans have an exoskeleton, which they moult to grow. They are distinguished from other groups of arthropods, such as insects, myriapods and chelicerates, by the possession of biramous (two-parted) limbs, and by their ...

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] |
Isopod
Isopoda is an order of crustaceans that includes woodlice and their relatives. Isopods live in the sea, in fresh water, or on land. All have rigid, segmented exoskeletons, two pairs of antennae, seven pairs of jointed limbs on the thorax, and five pairs of branching appendages on the abdomen that are used in respiration. Females brood their young in a pouch under their thorax. Isopods have various feeding methods: some eat dead or decaying plant and animal matter, others are grazers, or filter feeders, a few are predators, and some are internal or external parasites, mostly of fish. Aquatic species mostly live on the seabed or bottom of freshwater bodies of water, but some taxa can swim for a short distance. Terrestrial forms move around by crawling and tend to be found in cool, moist places. Some species are able to roll themselves into a ball as a defense mechanism or to conserve moisture. There are over 10,000 identified species of isopod worldwide, with around 4,5 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oregon
Oregon () is a U.S. state, state in the Pacific Northwest region of the Western United States. The Columbia River delineates much of Oregon's northern boundary with Washington (state), Washington, while the Snake River delineates much of its eastern boundary with Idaho. The 42nd parallel north, 42° north parallel delineates the southern boundary with California and Nevada. Oregon has been home to many Indigenous peoples of the Americas, indigenous nations for thousands of years. The first European traders, explorers, and settlers began exploring what is now Oregon's Pacific coast in the early-mid 16th century. As early as 1564, the Spanish expeditions to the Pacific Northwest, Spanish began sending vessels northeast from the Philippines, riding the Kuroshio Current in a sweeping circular route across the northern part of the Pacific. In 1592, Juan de Fuca undertook detailed mapping and studies of ocean currents in the Pacific Northwest, including the Oregon coast as well as ...

Clausidium Vancouverense
''Clausidium vancouverense'', the red copepod, is a symbiont of the ghost shrimp ''Neotrypaea californiensis''.

Pacific Staghorn Sculpin
The Pacific staghorn sculpin (''Leptocottus armatus'') is a species of marine ray-finned fish belonging to the family Cottidae, the typical sculpins. This species is found in the eastern Pacific Ocean. It is the only species in the monospecific genus ''Lepidocottus''.

Oyster Bed
Oyster is the common name for a number of different families of salt-water bivalve molluscs that live in marine or brackish habitats. In some species, the valves are highly calcified, and many are somewhat irregular in shape. Many, but not all oysters are in the superfamily Ostreoidea. Some types of oysters are commonly consumed (cooked or raw), and in some locales are regarded as a delicacy. Some types of pearl oysters are harvested for the pearl produced within the mantle. Windowpane oysters are harvested for their translucent shells, which are used to make various kinds of decorative objects. Etymology The word ''oyster'' comes from Old French , and first appeared in English during the 14th century. The French derived from the Latin , the feminine form of , which is the latinisation of the Ancient Greek () 'oyster'. Compare () 'bone'. Types True oysters True oysters are members of the family Ostreidae. This family includes the edible oysters, which mainly belong t ...
