The anchialine pool snail, scientific name Neritilia hawaiiensis, is a species living in brackish estuaries and in anchialine pools. [2] These snails have an operculum, and are aquatic gastropod mollusk in the family Neritiliidae.
This species is endemic to the islands of Hawaii, United States, and lives only in brackish estuaries and in anchialine pools, [2] which are marine pools that have no surface connection with the ocean but that are salty and that fluctuate in level with the tides.
Brackish water, also sometimes termed brack water, is water occurring in a natural environment having more salinity than freshwater, but not as much as seawater. It may result from mixing seawater with fresh water together, as in estuaries, or it may occur in brackish fossil aquifers. The word comes from the Middle Dutch root brak. Certain human activities can produce brackish water, in particular civil engineering projects such as dikes and the flooding of coastal marshland to produce brackish water pools for freshwater shrimp farming. Brackish water is also the primary waste product of the salinity gradient power process. Because brackish water is hostile to the growth of most terrestrial plant species, without appropriate management it is damaging to the environment.
The American black duck is a large dabbling duck in the family Anatidae. It was described by William Brewster in 1902. It is the heaviest species in the genus Anas, weighing 720–1,640 g (1.59–3.62 lb) on average and measuring 54–59 cm (21–23 in) in length with a 88–95 cm (35–37 in) wingspan. It somewhat resembles the female and eclipse male mallard in coloration, but has a darker plumage. The male and female are generally similar in appearance, but the male's bill is yellow while the female's is dull green with dark marks on the upper mandible. It is native to eastern North America. During the breeding season, it is usually found in coastal and freshwater wetlands from Saskatchewan to the Atlantic in Canada and the Great Lakes and the Adirondacks in the United States. It is a partially migratory species, mostly wintering in the east-central United States, especially in coastal areas.
Punaluʻu Beach is a beach between Pāhala and Nāʻālehu on the Big Island of the U.S. state of Hawaii. The beach has black sand made of basalt and created by lava flowing into the ocean which explodes as it reaches the ocean and cools. This volcanic activity is in the Hawaiʻi Volcanoes National Park. Punaluʻu is frequented by endangered hawksbill and green turtles, which can often be seen basking on the black sand.
The EcoSphere and "Original Ecosphere" are trademark names for sealed blown-glass miniature aquaria produced by Ecosphere Associates, Inc., of Tucson, Arizona, United States. Spherical or ovoid, the aquaria range from roughly pool-ball-size to basket-ball-size. They are sold worldwide as scientific novelties and decorative objects.
An anchialine pool or pond is a landlocked body of water with a subterranean connection to the ocean. Anchialine pools are a feature of coastal aquifers which are density stratified, with the water near the surface being fresh or brackish, and saline water intruding from the coast below at some depth. Depending on the site, it is sometimes possible to access the deeper saline water directly in the anchialine pool, or sometimes it may be accessible by cave diving.
The starlet sea anemone is a species of small sea anemone in the family Edwardsiidae native to the east coast of the United States, with introduced populations along the coast of southeast England and the west coast of the United States. Populations have also been located in Nova Scotia, Canada. This sea anemone is found in the shallow brackish water of coastal lagoons and salt marshes where its slender column is usually buried in the mud and its tentacles exposed. Its genome has been sequenced and it is cultivated in the laboratory as a model organism, but the IUCN has listed it as being a "Vulnerable species" in the wild.
Halocaridina rubra, the Hawaiian red shrimp or volcano shrimp is a small red shrimp of the family Atyidae, with the common Hawaiian name ʻōpaeʻula.
Dichotomyctere ocellatus, commonly the figure 8 puffer or eyespot puffer, is a pufferfish found in freshwater in Southeast Asia. It is known from the lower reaches of the Mekong (Cambodia), the Peninsular Malaysia as well as Borneo.
The white mullet or silver mullet is a tropical and subtropical marine fish of the family Mugilidae. It is commonly about 30 cm long.
Pelecus cultratus, commonly known as the ziege, sichel, sabre carp or sabrefish, is a cyprinid fish species from Eastern Europe and adjacent Asian regions, the only one in its genus, inhabiting the lower reaches of rivers and brackish waters in the eastern Baltic Sea, Black Sea, Caspian Sea and Aral Sea basins. The ziege having no major threats, the IUCN lists it as being of Least Concern.
Sicyopterus stimpsoni, commonly known as the Nopoli rockclimbing goby, oopu nopili, or Stimpson's goby, is a species of amphidromous goby endemic to Hawaii. This species can reach a length of 19.8 centimetres (7.8 in) SL.
Lyropupa hawaiiensis is a species of air-breathing land snail, terrestrial pulmonate gastropod mollusk in the family Pupillidae. This species is endemic to the United States.
Neritilia is a genus of freshwater snails which live near the sea coast in submarine caves. They have an operculum, and are aquatic gastropod mollusks in the family Neritiliidae.
Neritilia manoeli is a species of minute freshwater snail with an operculum, an aquatic gastropod mollusc or micromollusk in the family Neritiliidae.
The California brackish water snail, also known as the mimic tryonia, scientific name Tryonia imitator, is a species of very small brackish water snails that have an operculum, aquatic gastropod mollusks in the family Hydrobiidae.
Barbouria is a genus of shrimp in the family Barbouriidae, comprising two species.
Typhlatya is a genus of shrimp in the family Atyidae. These are small, stygobitic shrimp found in the West Mediterranean region, Caribbean region, Ascension Island and the Galápagos, although the individual species often have very small ranges. Species in this genus are found in salt, brackish and fresh waters, mostly in anchialine habitats and none in the open sea.
Coastal fish, also called inshore fish or neritic fish, inhabit the sea between the shoreline and the edge of the continental shelf. Since the continental shelf is usually less than 200 metres (660 ft) deep, it follows that pelagic coastal fish are generally epipelagic fish, inhabiting the sunlit epipelagic zone. Coastal fish can be contrasted with oceanic fish or offshore fish, which inhabit the deep seas beyond the continental shelves.
Hurst Castle and Lymington River Estuary is a 1,077.3-hectare (2,662-acre) biological and geological Site of Special Scientific Interest near Lymington in Hampshire. It is a Nature Conservation Review site and two areas are Geological Conservation Review sites. Three areas are local nature reserves, Boldre Foreshore, Sturt Pond and Lymington and Keyhaven Marshes; the latter site is managed by the Hampshire and Isle of Wight Wildlife Trust. Part of it is North Solent National Nature Reserve. It is part of Solent and Southampton Water Ramsar site and Special Protection Area. Parts of it are in Solent Maritime and Solent and Isle of Wight Lagoons Special Areas of Conservation.
