Metabetaeus Lohena
''Metabetaeus lohena'', also known as the alpha snapping shrimp or anchialine snapping shrimp, is a species of alpheid shrimp native to Hawaii and Easter Island.Anker, Arthur, 2010, Metabetaeus Borradaile, 1899 revisited, with description of a new marine species from French Polynesia (Crustacea: Decapoda: Alpheidae), Zootaxa 2552, pp. 37-54 : 51-53 DOI:10.5281/zenodo.6206644 Description ''Metabetaeus lohena'' is an alpheid scavenger, which will also hunt small anchialine invertebrates. ''M. lohena'' grows to lengths of 18 mm and are pale pink to vibrant red in colour. Shrimp possess large claws and a clearly visible mandibular spot. Females once gravid will produce a mass of 20 to 29 eggs. ''M. lohena'' larvae lack a yolk sack, which suggests the species possess a planktotrophic larval feeding phase. ''M. lohena'' have been recorded to live for up to 6 years. Distribution and habitat ''Metabetaeus lohena'' has a widespread distribution in Hawaii where it is native to m ...

Alpheidae
Alpheidae is a family of caridean snapping shrimp, characterized by having asymmetrical claws, the larger of which is typically capable of producing a loud snapping sound. Other common names for animals in the group are pistol shrimp or alpheid shrimp. The family is diverse and worldwide in distribution, consisting of about 1,119 species within 38 or more genera. The two most prominent genera are ''Alpheus'' and ''Synalpheus'', with species numbering well over 250 and 100, respectively. Most snapping shrimp dig burrows and are common inhabitants of coral reefs, submerged seagrass flats, and oyster reefs. While most genera and species are found in tropical and temperate coastal and marine waters, ''Betaeus'' inhabits cold seas and ''Potamalpheops'' is found only in freshwater caves. When in colonies, the snapping shrimp can interfere with sonar and underwater communication. The shrimp are considered a major source of sound in the ocean.

Hawaii
Hawaii ( ; haw, Hawaii or ) is a state in the Western United States, located in the Pacific Ocean about from the U.S. mainland. It is the only U.S. state outside North America, the only state that is an archipelago, and the only state geographically located within the tropics. Hawaii comprises nearly the entire Hawaiian archipelago, 137 volcanic islands spanning that are physiographically and ethnologically part of the Polynesian subregion of Oceania. The state's ocean coastline is consequently the fourth-longest in the U.S., at about . The eight main islands, from northwest to southeast, are Niihau, Kauai, Oahu, Molokai, Lānai, Kahoolawe, Maui, and Hawaii—the last of these, after which the state is named, is often called the "Big Island" or "Hawaii Island" to avoid confusion with the state or archipelago. The uninhabited Northwestern Hawaiian Islands make up most of the Papahānaumokuākea Marine National Monument, the United States' largest protected ...

Hawaii Department Of Land And Natural Resources
The Hawaii Department of Land and Natural Resources (DLNR) is a part of the Government of Hawaii, Hawaii state government dedicated to managing, administering, and exercising control over public lands, water resources and streams, ocean waters, coastal areas, minerals, and other natural resources of the State of Hawaii, Hawaiʻi. The mission of the Hawaiʻi Department of Land and Natural Resources is to "enhance, protect, conserve and manage Hawaiʻi's unique and limited natural, cultural and historic resources held in public trust for current and future generations of the people of Hawaiʻi nei, and its visitors, in partnership with others from the public and private sectors." The organization oversees over 1.3 million acres of land, beaches, and coastal waters and 750 miles of coastal land. The DLNR is established in the Hawaiʻi Revised Statutes §26-15 and establishes the Board of Land Natural Resources as the governing entity.

Easter Island
Easter Island ( rap, Rapa Nui; es, Isla de Pascua) is an island and special territory of Chile in the southeastern Pacific Ocean, at the southeasternmost point of the Polynesian Triangle in Oceania. The island is most famous for its nearly 1,000 extant monumental statues, called ''moai'', which were created by the early Rapa Nui people. In 1995, UNESCO named Easter Island a World Heritage Site, with much of the island protected within Rapa Nui National Park. Experts disagree on when the island's Polynesian inhabitants first reached the island. While many in the research community cited evidence that they arrived around the year 800, there is compelling evidence presented in a 2007 study that places their arrival closer to 1200. The inhabitants created a thriving and industrious culture, as evidenced by the island's numerous enormous stone ''moai'' and other artifacts. However, land clearing for cultivation and the introduction of the Polynesian rat led to gradual deforest ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scavenger
Scavengers are animals that consume dead organisms that have died from causes other than predation or have been killed by other predators. While scavenging generally refers to carnivores feeding on carrion, it is also a herbivorous feeding behavior. Scavengers play an important role in the ecosystem by consuming dead animal and plant material. ''Decomposers'' and detritivores complete this process, by consuming the remains left by scavengers. Scavengers aid in overcoming fluctuations of food resources in the environment. The process and rate of scavenging is affected by both biotic and abiotic factors, such as carcass size, habitat, temperature, and seasons. Etymology Scavenger is an alteration of ''scavager,'' from Middle English ''skawager'' meaning "customs collector", from ''skawage'' meaning "customs", from Old North French ''escauwage'' meaning "inspection", from ''schauwer'' meaning "to inspect", of Germanic origin; akin to Old English ''scēawian'' and German ' ...

Anchialine Pools
An anchialine system (, from Greek ''ankhialos'', "near the sea") is a landlocked body of water with a subterranean connection to the ocean. Depending on its formation, these systems can exist in one of two primary forms: pools or caves. The primary differentiating characteristics between pools and caves is the availability of light; cave systems are generally aphotic while pools are euphotic. The difference in light availability has a large influence on the biology of a given system. Anchialine systems are a feature of coastal aquifers which are density stratified, with water near the surface being fresh or brackish, and saline water intruding from the coast at 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. Anchialine systems are extremely common worldwide especially along neotropical coastlines where the geology and aquifer systems are relatively young, ...

Halocaridina Rubra
''Halocaridina rubra'', the Hawaiian red shrimp or volcano shrimp is a small red shrimp of the family Atyidae, with the common Hawaiian name (meaning "red shrimp"). Description and distribution It is a small red shrimp, rarely longer than in length, typically found in brackish water pools near the sea shore, sometimes in large numbers. Such pools are referred to as anchialine pools (from the Greek ' = near the sea). ''Halocaridina rubra'' is endemic to the Hawaiian islands, and most commonly found in anchialine pools in fresh lava substrates on Hawaii and Maui Island; it has also been found in limestone karst pools and hypogeal habitats in limestone on older islands, such as Oahu. Its habitat is unique and sparsely represented on five of the eight high Hawaiian Islands (Maui, Kahoolawe, Oahu, Molokai and Hawaii). Ecology are herbivorous and detritivorous shrimp occupying both hypogeal (subterranean) and epigeal (surface) anchialine waters. Typical food of is algal and ...

Crustaceans Described In 1960
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 ...
