Gelliodes Wilsoni
''Gelliodes wilsoni'', sometimes known as the gray encrusting sponge, is a species of sponge found in shallow water in the Philippines. It was first described in 1925 by the American zoologist Edmund Beecher Wilson, the type locality being North Sulawesi. He gave it the name ''Gelliodes fibrosa'', a name already used in 1905 for a species in the Gulf of Mannar, Sri Lanka. In 2013, Carballo, Aquilar-Camacho, Knapp & Bell, decided that this was a homonym, a separate taxon from the original one given that name, and gave the new species the name ''Gelliodes wilsoni''. Description ''Gelliodes wilsoni'' varies somewhat in growth form but is usually found as a thick encrusting mat with irregular branches that overgrow each other, sometimes joining together, and sometimes forming short erect branches. It is usually bluish-grey, with a beige-grey interior. The texture is spongy but fibrous, elastic and tough and the surface may be smooth or may have irregular tufts of fibres protruding. ...

Sponge
Sponges, the members of the phylum Porifera (; meaning 'pore bearer'), are a basal animal clade as a sister of the diploblasts. They are multicellular organisms that have bodies full of pores and channels allowing water to circulate through them, consisting of jelly-like mesohyl sandwiched between two thin layers of cells. Sponges have unspecialized cells that can transform into other types and that often migrate between the main cell layers and the mesohyl in the process. Sponges do not have nervous, digestive or circulatory systems. Instead, most rely on maintaining a constant water flow through their bodies to obtain food and oxygen and to remove wastes. Sponges were first to branch off the evolutionary tree from the last common ancestor of all animals, making them the sister group of all other animals. Etymology The term ''sponge'' derives from the Ancient Greek word ( 'sponge'). Overview Sponges are similar to other animals in that they are multicellular, he ...

Environmental Impact Of Shipping
The environmental effects of shipping include air pollution, water pollution, #Sound pollution, acoustic, and oil pollution. Ships are responsible for more than 18 percent of some air pollutants. As for greenhouse gas emissions, the International Maritime Organization (IMO) estimates that carbon dioxide emissions from shipping were equal to 2.89% of the global human-made emissions in 2018 and expects them to rise to 90-130% of 2008 emissions by 2050 if no action is taken. Although in the movement of a given mass of cargo a given distance, ships are the Energy efficiency in transport, most energy-efficient method, the sheer size of the maritime transport industry means that it has a significant effect on the environment.

Fungiidae
The Fungiidae () are a family of Cnidaria, commonly known as mushroom corals or plate corals. The family contains thirteen extant genera. They range from solitary corals to colonial species. Some genera such as ''Cycloseris'' and ''Fungia'' are solitary organisms, '' Polyphyllia'' consists of a single organism with multiple mouths, and ''Ctenactis'' and '' Herpolitha'' might be considered as solitary organisms with multiple mouths or a colony of individuals, each with its separate mouth. Characteristics Species are generally solitary marine animals capable of benthic locomotion. These corals often appear to be bleached or dead. In most genera, a single polyp emerges from the center of the skeleton to feed at night. Most species remain fully detached from the substrate in adulthood. Some are immobile as well as colonial. Ecology Some species of mushroom coral such as ''Fungia repanda'' and ''Ctenactis echinata'' are able to change sex. This is posited to take place in resp ...

Kaneohe Bay
Kāneohe () is a census-designated place (CDP) included in the City and County of Honolulu and located in Hawaii state District of Koolaupoko on the island of Oahu. In the Hawaiian language, ''kāne ohe'' means "bamboo man". According to an ancient Hawaiian story a local woman compared her husband's cruelty to the sharp edge of cutting bamboo; thus the place was named Kāneohe or "bamboo man". The population was 37,430 at the 2020 census. Kāneohe is the largest of several communities along Kāneohe Bay and one of the two largest residential communities on the windward side of Oahu (the other is Kailua). The commercial center of the town is spread mostly along Kamehameha Highway. From ancient times, Kāneohe was important as an agricultural area, owing to an abundance of rainfall. Today, Kāneohe is mostly a residential community, with very little agriculture in evidence. The only commercial crop of any consequence in the area is banana. Features of note are Hoomaluhia Bo ...

Biofouling
Biofouling or biological fouling is the accumulation of microorganisms, plants, algae, or small animals where it is not wanted on surfaces such as ship and submarine hulls, devices such as water inlets, pipework, grates, ponds, and rivers that cause degradation to the primary purpose of that item. Such accumulation is referred to as '' epibiosis'' when the host surface is another organism and the relationship is not parasitic. Since biofouling can occur almost anywhere water is present, biofouling poses risks to a wide variety of objects such as boat hulls and equipment, medical devices and membranes, as well as to entire industries, such as paper manufacturing, food processing, underwater construction, and desalination plants. Anti-fouling is the ability of specifically designed materials (such as toxic biocide paints, or non-toxic paints) to remove or prevent biofouling. The buildup of biofouling on marine vessels poses a significant problem. In some instances, the hull struc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Species Description
A species description is a formal description of a newly discovered species, usually in the form of a scientific paper. Its purpose is to give a clear description of a new species of organism and explain how it differs from species that have been described previously or are related. In order for species to be validly described, they need to follow guidelines established over time. Zoological naming requires adherence to the ICZN code, plants, the ICN, viruses ICTV, and so on. The species description often contains photographs or other illustrations of type material along with a note on where they are deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million species have been identified and described, out of some 8.7 million that may actually exist. Millions more have become extinct throughout the existence of life on Earth. Naming process A name of a new species becomes valid (available in zo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
