Clingfishes
Clingfishes are fishes of the family Gobiesocidae, the only family in the order Gobiesociformes. These fairly small to very small fishes are widespread in tropical and temperate regions, mostly near the coast, but a few species in deeper seas or fresh water. Most species shelter in shallow reefs or seagrass beds, clinging to rocks, algae and seagrass leaves with their sucking disc, a structure on their chest. They are generally too small to be of interest to fisheries, although the relatively large ''Sicyases sanguineus'' regularly is caught as a food fish, and some of the other species occasionally appear in the marine aquarium trade. Distribution and habitat Clingfishes are primarily found near the shore in the Atlantic, Indian and Pacific Oceans, including marginal seas such as the Mediterranean, Gulf of Mexico, Caribbean and Gulf of California. The greatest species richness is in tropical and warm temperate regions, but the range of a few extends into colder waters, like ...

Diplecogaster Bimaculata
''Diplecogaster bimaculata'', the two-spotted clingfish, is a species of fish in the family Gobiesocidae found in Black Sea, Mediterranean Sea and Atlantic Ocean where it is found on rocks and among seagrass or shell beds. Description The species has pelvic fins modified to create a sucker which is used for clinging to rocks or other hard surfaces. It shows variable colouration and its body is frequently coloured red and is spotted with violet, blue, brown or yellow, and they have a yellowish ventral surface. They are sexually dimorphic and the males show a purple spot, surrounded by yellow, immediately to the rear of their pectoral fin. It has a flattened body and a small head, which is roughly triangular in shape. The single dorsal and anal fin are situated posteriorly near to the tail and both are separate from the caudal fin which sits at the end of a long caudal peduncle. It has large eyes and a short snout which ends in large, fleshy lips and very small gill openings. This ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lepadogaster Lepadogaster
The shore clingfish (''Lepadogaster lepadogaster'') is a clingfish of the family Gobiesocidae. It is found in the Mediterranean Sea and adjacent Atlantic Ocean north to Galicia, Spain. Description Distribution Occurs in the eastern Atlantic from Galicia, Spain to the Mediterranean, between latitudes 43.8° N and 30° N. Habitat and Biology ''L. lepadogaster'' often inhabits underwater boulder fields consisting of smooth rocks and large pebbles. Its length is up to 65 mm. ''L. lepadogaster'' is also classified as a cryptobenthic fish. Cryptobenthic simply means that the fish is both behaviorally and visually cryptic. The term is also used mainly to describe adult fish of a certain size, roughly around 5 cm in length. The clingfish gets its name from the ability of the fish to attach itself to the rock walls of the ocean shore. It does this by having pelvic fins that have been adapted to form suckers. These suckers keep the clingfish strongly attached to the rocky surf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lepadogaster Candolii
''Lepadogaster candolii'', common name Connemarra clingfish, is a species of fish in the genus '' Lepadogaster''. It occurs in the Eastern Atlantic from the British Isles (off the coast of Western Scotland and South-West England and Ireland) south to Madeira and the Canary Islands and into the western Mediterranean and the Black Sea. The specific name ''candolii'' honours the Swiss botanist Augustin Pyramus de Candolle (1778-1841) and has various spellings: ''candolii'', ''candolei'', ''candollei'', and ''decandollii'', but only the first one is correct. Some workers have found that ''L. candolii'' is not closely related to the other two species in the genus '' Lepadogaster'' and have proposed the placing of this species in the revived monotypic genus ''Mirbelia'' Canestrini, 1864, at least until more definitive taxonomic studies can be undertaken. ''L. candolii'' is considered a euryecious species, meaning that it has a broad variety of living conditions and habitats that it ...

Norway
Norway, officially the Kingdom of Norway, is a Nordic country in Northern Europe, the mainland territory of which comprises the western and northernmost portion of the Scandinavian Peninsula. The remote Arctic island of Jan Mayen and the archipelago of Svalbard also form part of Norway. Bouvet Island, located in the Subantarctic, is a dependency of Norway; it also lays claims to the Antarctic territories of Peter I Island and Queen Maud Land. The capital and largest city in Norway is Oslo. Norway has a total area of and had a population of 5,425,270 in January 2022. The country shares a long eastern border with Sweden at a length of . It is bordered by Finland and Russia to the northeast and the Skagerrak strait to the south, on the other side of which are Denmark and the United Kingdom. Norway has an extensive coastline, facing the North Atlantic Ocean and the Barents Sea. The maritime influence dominates Norway's climate, with mild lowland temperatures on the se ...

Algae
Algae (; singular alga ) is an informal term for a large and diverse group of photosynthetic eukaryotic organisms. It is a polyphyletic grouping that includes species from multiple distinct clades. Included organisms range from unicellular microalgae, such as ''Chlorella,'' ''Prototheca'' and the diatoms, to multicellular forms, such as the giant kelp, a large brown alga which may grow up to in length. Most are aquatic and autotrophic (they generate food internally) and lack many of the distinct cell and tissue types, such as stomata, xylem and phloem that are found in land plants. The largest and most complex marine algae are called seaweeds, while the most complex freshwater forms are the ''Charophyta'', a division of green algae which includes, for example, ''Spirogyra'' and stoneworts. No definition of algae is generally accepted. One definition is that algae "have chlorophyll ''a'' as their primary photosynthetic pigment and lack a sterile covering of cells around thei ...

Seagrass Meadow
A seagrass meadow or seagrass bed is an underwater ecosystem formed by seagrasses. Seagrasses are marine (saltwater) plants found in shallow coastal waters and in the brackish waters of estuaries. Seagrasses are flowering plants with stems and long green, grass-like leaves. They produce seeds and pollen and have roots and rhizomes which anchor them in seafloor sand. Seagrasses form dense underwater meadows which are among the most productive ecosystems in the world. They provide habitats and food for a diversity of marine life comparable to that of coral reefs. This includes invertebrates like shrimp and crabs, cod and flatfish, marine mammals and birds. They provide refuges for endangered species such as seahorses, turtles, and dugongs. They function as nursery habitats for shrimps, scallops and many commercial fish species. Seagrass meadows provide coastal storm protection by the way their leaves absorb energy from waves as they hit the coast. They keep coastal waters healthy ...

Coral Reef
A coral reef is an underwater ecosystem characterized by reef-building corals. Reefs are formed of colonies of coral polyps held together by calcium carbonate. Most coral reefs are built from stony corals, whose polyps cluster in groups. Coral belongs to the class Anthozoa in the animal phylum Cnidaria, which includes sea anemones and jellyfish. Unlike sea anemones, corals secrete hard carbonate exoskeletons that support and protect the coral. Most reefs grow best in warm, shallow, clear, sunny and agitated water. Coral reefs first appeared 485 million years ago, at the dawn of the Early Ordovician, displacing the microbial and sponge reefs of the Cambrian. Sometimes called ''rainforests of the sea'', shallow coral reefs form some of Earth's most diverse ecosystems. They occupy less than 0.1% of the world's ocean area, about half the area of France, yet they provide a home for at least 25% of all marine species, including fish, mollusks, worms, crustaceans, echinoderms, sp ...

Gobiesox
''Gobiesox'' is a genus of clingfishes found in the Americas, including offshore islands. Most species inhabit coastal marine and brackish waters, but ''G. lanceolatus'' is a deep-water species found at a depth of around , and seven species (''G. cephalus'', ''G. fluviatilis'', ''G. fulvus'', ''G. juniperoserrai'', ''G. juradoensis'', ''G. mexicanus'' and ''G. potamius'') are from fast-flowing rivers and streams. These seven are the only known freshwater clingfish. The genus includes both widespread and common species, and more restricted species that are virtually unknown. Three freshwater species that are endemic to Mexico (''G. fluviatilis'', ''G. juniperoserrai'' and ''G. mexicanus'') are considered threatened by Mexican authorities, and three species that are endemic to small offshore islands (''G aethus'' and ''G. canidens'' of the Revillagigedo Islands, and ''G. woodsi'' of Cocos Island) are considered vulnerable by the IUCN. ''Gobiesox'' are small fish, mostly less than ... [...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. To the north are the Chukchi and Beaufort Seas of the Arctic Ocean, while the Pacific Ocean lies to the south and southwest. Alaska is by far the largest U.S. state by area, comprising more total area than the next three largest states (Texas, California, and Montana) combined. It represents the seventh-largest subnational division in the world. It is the third-least populous and the most sparsely populated state, but by far the continent's most populous territory located mostly north of the 60th parallel, with ...
