Kelps are large brown algae or seaweeds that make up the order Laminariales. There are about 30 different genera. Despite its appearance, kelp is not a plant but a stramenopile.
Kelp forests are underwater areas with a high density of kelp, which covers a large part of the world's coastlines. Smaller areas of anchored kelp are called kelp beds. They are recognized as one of the most productive and dynamic ecosystems on Earth. Although algal kelp forest combined with coral reefs only cover 0.1% of Earth's total surface, they account for 0.9% of global primary productivity. Kelp forests occur worldwide throughout temperate and polar coastal oceans. In 2007, kelp forests were also discovered in tropical waters near Ecuador.
Eleotridae is a family of fish commonly known as sleeper gobies, with about 34 genera and 180 species. Most species are found in the tropical Indo-Pacific region, but there are also species in subtropical and temperate regions, warmer parts of the Americas and near the Atlantic coast in Africa. While many eleotrids pass through a planktonic stage in the sea and some spend their entire lives in the sea; as adults, the majority live in freshwater streams and brackish water. One of its genera, Caecieleotris, is troglobitic. They are especially important as predators in the freshwater stream ecosystems on oceanic islands such as New Zealand and Hawaii that otherwise lack the predatory fish families typical of nearby continents, such as catfish. Anatomically, they are similar to the gobies (Gobiidae), though unlike the majority of gobies, they do not have a pelvic sucker.
The bank cormorant, also known as Wahlberg's cormorant, is a medium-sized cormorant that is endemic to Namibia and the western seaboard of South Africa, living in and around coastal waters; it is rarely recorded more than 15 km offshore.
Eucyclogobius newberryi, the northern tidewater goby, is a species of goby native to lagoons of streams, marshes, and creeks along the coast of California, United States. The northern tidewater goby is one of six native goby species of California. It is protected under the Endangered Species Act as an endangered species of the United States since 1994.
Paralabrax clathratus, the kelp bass, bull bass or calico bass, is a species of marine ray-finned fish, from the subfamily Serraninae, classified as part of the family Serranidae which includes the groupers and anthias. It is found in the eastern North Pacific Ocean where it is an important species for both recreational and commercial fisheries.
A blind fish is a fish without functional eyes. Most blind fish species are found in dark habitats such as the deep ocean, deep river channels and underground.
The two-spotted goby is a species of goby native to marine and brackish waters of the eastern Atlantic Ocean where it can be found from the Faeroes and Norway to the northwestern coast of Spain. It has also been recorded from Estonia though records from the Mediterranean Sea are uncertain. They are common on all coasts of the United Kingdom. This species can reach a length of 6 centimetres (2.4 in) TL.
The Gobiiformes are an order of fish that includes the gobies and their relatives. The order, which was previously considered a suborder of Perciformes, is made up of about 2,211 species that are divided between seven families. Phylogenetic relationships of the Gobiiformes have been elucidated using molecular data. Gobiiforms are primarily small species that live in marine water, but roughly 10% of these species inhabit fresh water. This order is composed chiefly of benthic or burrowing species; like many other benthic fishes, most gobiiforms do not have a gas bladder or any other means of controlling their buoyancy in water, so they must spend most of their time on or near the bottom. Gobiiformes means "goby-like".
The rock goby is a small coastal goby of eastern Atlantic waters, from Scotland to Senegal. It is also reported from the Mediterranean and Black Seas, and is an anti-Lessepsian migrant in the Gulf of Aqaba and the Red Sea. There are unconfirmed records from the area around Pointe Noire in Congo-Brazzaville.
Cavefish or cave fish is a generic term for fresh and brackish water fish adapted to life in caves and other underground habitats. Related terms are subterranean fish, troglomorphic fish, troglobitic fish, stygobitic fish, phreatic fish, and hypogean fish.
The violet goby is a species of goby native to marine, fresh and brackish waters near the Atlantic coast of North and South America from South Carolina in the United States of America, to northern Brazil. It prefers bays, estuaries and river mouths with muddy substrates. It is often marketed as the dragon goby or dragon fish.
Lamprologus lethops is a species of cichlid fish from areas with fast current in the Congo River in Central Africa, where it is believed to live in depths as great as 160 m (520 ft) or 200 m (660 ft) below the surface. It reaches up to about 12.5 cm (5 in) in standard length, with females being somewhat smaller than males, is all whitish in color (non-pigmented), and essentially blind as adult, as their eyes are covered in a thick layer of skin. This is entirely unique among cichlids and an adaption to the perpetual darkness of its habitat, similar to the adaptions seen in cavefish. The eyes of juveniles are rudimentary and not covered by skin.
The Gobionellinae are a subfamily of fish which was formerly classified in the family Gobiidae, the gobies, but the 5th Edition of Fishes of the World classifies the subfamily as part of the family Oxudercidae. Members of Gobionellinae mostly inhabit estuarine and freshwater habitats; the main exception is the genus Gnatholepis, which live with corals in marine environments. The subfamily is distributed in tropical and temperate regions around the world with the exception of the northeastern Atlantic Ocean, the Mediterranean Sea, and the Ponto-Caspian region. It includes around 370 species and 55 genera: Wikipedia articles about genera list about 389 species.
Rhinogobiops is a genus of true gobies in the family Gobiidae. It is monotypic, being represented by the single species, Rhinogobiops nicholsii, also known as the blackeye goby, bluespot goby, and crested goby. They are common inhabitants of coral reefs and rocky habitats along the eastern Pacific Ocean coasts of Mexico, the United States, and Canada, although they are hardly noticed, as they often rest motionless near their shelters.
The blind goby is a species of fish in the goby family Oxudercidae, the only species in the genus Typhlogobius. It is native to the coastlines of southern California in the United States and Baja California in Mexico, where it commonly inhabits the burrows of shrimp of the genus Callianassa. The adult of the species is completely blind and lacks pigmentation, while the juvenile has rudimentary eyes that help it find the shrimp burrows. This species can reach a length of 8.3 centimetres (3.3 in) TL.
Acanthogobius flavimanus is a species of fish in the goby family known by the common name yellowfin goby. Other common names include mahaze, Japanese river goby, Oriental goby, and spotted goby. It is native to Asia, where its range includes China, Japan, Korea, parts of Russia, Vietnam, and Malaysia. It has spread beyond its native range to become an introduced, and often invasive, species. It has been recorded in Australia, Mexico, and Florida and California in the United States.
Sebastes atrovirens, the kelp rockfish, is a species of marine ray-finned fish belonging to the subfamily Sebastinae, the rockfishes, part of the family Scorpaenidae. It is native to the Pacific Ocean along the coast of California in the United States and Baja California in Mexico.
Goby is a common name for many species of small to medium sized ray-finned fish, normally with large heads and tapered bodies, which are found in marine, brackish and freshwater environments.
