Conservation-dependent
A conservation-dependent species is a species which has been categorized as "Conservation Dependent" ("LR/cd") by the International Union for Conservation of Nature (IUCN), as dependent on conservation efforts to prevent it from becoming endangered. A species that is reliant on the conservation attempts of humans is considered conservation dependent. Such species must be the focus of a continuing species-specific and/or habitat-specific conservation program, the cessation of which would result in the species qualifying for one of the threatened categories within a period of five years. The determination of status is constantly monitored and can change. This category is part of the IUCN 1994 Categories & Criteria (version 2.3), which is no longer used in evaluation of taxa, but persists in the IUCN Red List for taxa evaluated prior to 2001, when version 3.1 was first used. Using the 2001 (version 3.1) system these taxa are classed as near threatened, but those that have not been ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Near-threatened Species
A near-threatened species is a species which has been categorized as "Near Threatened" (NT) by the International Union for Conservation of Nature (IUCN) as that may be vulnerable to endangerment in the near future, but it does not currently qualify for the threatened status. The IUCN notes the importance of reevaluating near-threatened taxa at appropriate intervals. The rationale used for near-threatened taxa usually includes the criteria of vulnerable which are plausible or nearly met, such as reduction in numbers or range. Those designated since 2001 that depend on conservation efforts to not become threatened are no longer separately considered conservation-dependent species. IUCN Categories and Criteria version 2.3 Before 2001, the IUCN used the version 2.3 Categories and Criteria to assign conservation status, which included a separate category for conservation-dependent species ("Conservation Dependent", LR/cd). With this category system, Near Threatened and Con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Least-concern Species
A least-concern species is a species that has been evaluated and categorized by the International Union for Conservation of Nature (IUCN) as not being a focus of wildlife conservation because the specific species is still plentiful in the wild. They do not qualify as threatened, near threatened, or (before 2001) conservation dependent. Species cannot be assigned the "Least Concern" category unless they have had their population status evaluated. That is, adequate information is needed to make a direct, or indirect, assessment of its risk of extinction based on its distribution or population status. Evaluation Since 2001 the category has had the abbreviation "LC", following the IUCN 2001 Categories & Criteria (version 3.1). Before 2001 "least concern" was a subcategory of the " Lower Risk" category and assigned the code "LR/lc" or lc. Around 20% of least concern taxa (3261 of 15,636) in the IUCN database still use the code "LR/lc", which indicates they have not been re- ...

Bear Paw Clam
''Hippopus hippopus'', also known as the Horse Hoof clam and Strawberry clam, is a species of giant clam in the Subfamily Tridacninae and the genus ''Hippopus''. ''Hippopus'' is a delicacy in many Southeast Asian countries due to its high quality meat. The scientific name ''hippopus'' comes from Ancient Greek for "horse foot" (ἵππος, hippos, "horse", and πούς, pous, "foot"). Distribution and habitat ''H. hippopus'' is found in tropical waters of the Indian and Pacific Oceans. It is commonly found on the coast of Indonesia and Palau. Its range extends as far as India in the Indian Ocean, and Kiribati in the Pacific Ocean. ''H. hippopus'' frequently inhabits the shallow waters of fringing, barrier reefs, and seagrass beds. Because ''H. hippopus'' inhabits the shallow water, its symbiotic inhabitants can use sunlight to perform photosynthesis for the clam. ''H. Hippopus'' does not attach to rocks in the reef, instead, they settle on sandy patches, detached from any ree ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Reptiles
Reptiles, as commonly defined, are a group of tetrapods with an ectothermic metabolism and Amniotic egg, amniotic development. Living traditional reptiles comprise four Order (biology), orders: Testudines, Crocodilia, Squamata, and Rhynchocephalia. About 12,000 living species of reptiles are listed in the Reptile Database. The study of the traditional reptile orders, customarily in combination with the study of modern amphibians, is called herpetology. Reptiles have been subject to several conflicting Taxonomy, taxonomic definitions. In Linnaean taxonomy, reptiles are gathered together under the Class (biology), class Reptilia ( ), which corresponds to common usage. Modern Cladistics, cladistic taxonomy regards that group as Paraphyly, paraphyletic, since Genetics, genetic and Paleontology, paleontological evidence has determined that birds (class Aves), as members of Dinosauria, are more closely related to living crocodilians than to other reptiles, and are thus nested among re ...

Retrieved on 2013-04-13. True to its common and scientific names, the black caiman has a dark greenish-black coloration as an adult. In some individuals, the pigmentation can appear almost jet-black. It has grey to brown banding on the lower jaw; juveniles have a more vibrant coloration compared to adults, with prominent white-pale yellow banding on the flanks that remains present well into adulthood (more than most other species). The banding on young helps with camouflage by breaki ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Mollusca
Mollusca is a phylum of protostome, protostomic invertebrate animals, whose members are known as molluscs or mollusks (). Around 76,000 extant taxon, extant species of molluscs are recognized, making it the second-largest animal phylum after Arthropoda. The number of additional fossil species is estimated between 60,000 and 100,000, and the proportion of undescribed species is very high. Many taxa remain poorly studied. Molluscs are the largest marine biology, marine phylum, comprising about 23% of all the named marine organisms. They are highly diverse, not just in size and anatomical structure, but also in behaviour and habitat, as numerous groups are freshwater mollusc, freshwater and even terrestrial molluscs, terrestrial species. The phylum is typically divided into 7 or 8 taxonomy (biology), taxonomic class (biology), classes, of which two are entirely extinct. Cephalopod molluscs, such as squid, cuttlefish, and octopuses, are among the most neurobiology, neurologi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Maxima Clam
The maxima clam (''Tridacna maxima''), also known as the small giant clam, is a species of bivalve mollusc found throughout the Indo-Pacific region.MolluscaBase eds. (2022). MolluscaBase. Tridacna maxima (Röding, 1798). Accessed through: World Register of Marine Species at: https://marinespecies.org/aphia.php?p=taxdetails&id=207675 on 2022-10-13 They are much sought after in the aquarium trade, as their often striking coloration mimics that of the true giant clam; however, the ''maximas'' maintain a manageable size, with the shells of large specimens typically not exceeding in length. Description Bivalves have two valves on the mantle. These siphon water through the body to extract oxygen from the water using the gills and to feed on algae.Ellis, S. (1998) Spawning and early larval rearing of giant clams (Bivalvia: Tridacnidae). Center for Tropical and Subtropical Aquaculture, 130: 1–55.

Mistichthys Luzonensis
The sinarapan or tabyos (''Mistichthys luzonensis'') is a species of fish in the goby subfamily, Gobionellinae, and the only member of the monotypic genus ''Mistichthys''. It is endemic to the Philippines, where it occurs along the Bicol River and in Lakes Buhi, Bato, Lakelets Katugday and Manapao (both in Buhi) in Camarines Sur and iDanao Lake in Polangui Albay. The fish grows up to 2.5 centimeters long. It is transparent with a few dark spots and black eyes. This freshwater fish lives in lakes from the shoreline to 12 meters in depth. Tabyos is considered a delicacy, and it is of economic importance locally. It has been listed in the ''Guinness Book of Records'' as the "smallest commercially-harvested food fish". It is harvested with nets and palm leaves. It tends to school, making it easier to catch. It has been taken in large numbers since the 1940s, when it first became popular as food. It is fried or boiled and served with vegetables. By the 1990s it had become clear t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
