Ballast Island (Japan)
Ballast Island, also known as Barasu Island (), is a small uninhabited coral island or cay in the Yaeyama Islands, Yaeyama chain off the coast of mainland Japan, located between the islands of Iriomote and Hatoma. The island sits at the center of a coral reef composed primarily of species of the Scleractinia, stony coral genus ''Acropora'', most numerously ''Acropora muricata''. At least four goby species have been found at the island, as well as a specimen of the moray eel ''Gymnothorax ryukyuensis''. Two small islets on the site had formed by the 1960s. A mass Coral bleaching, bleaching of the reef's corals from July to September 1998 led to the merging of the two islets, accelerated by the impact of several typhoons in 1998 and 1999. Ballast Island reached a maximum land area of around in late 1999, before steadily declining over the following years. , the island had a surface area of around , a size it has maintained since 2009. While uninhabited, the island is visited on snor ...

Acropora Intermedia
''Acropora'' is a genus of small polyp stony coral in the phylum Cnidaria. Some of its species are known as table coral, elkhorn coral, and staghorn coral. Over 149 species are described. ''Acropora'' species are some of the major reef corals responsible for building the immense calcium carbonate substructure that supports the thin living skin of a reef. Anatomy and distribution Depending on the species and location, ''Acropora'' species may grow as plates or slender or broad branches. Like other corals, ''Acropora'' corals are colonies of individual polyps, which are about 2 mm across and share tissue and a nerve net. The polyps can withdraw back into the coral in response to movement or disturbance by potential predators, but when undisturbed, they protrude slightly. The polyps typically extend further at night to help capture plankton and organic matter from the water. The species are distributed in the Indo-Pacific (over 100 species) and Caribbean (3 species).

ScienceDirect
ScienceDirect is a searchable web-based bibliographic database, which provides access to full texts of scientific and medical publications of the Dutch publisher Elsevier as well of several small academic publishers. It hosts over 18 million publications from more than 4,000 academic journals and 30,000 e-books. The access to the full-text requires subscription, while the bibliographic metadata are free to read. ScienceDirect was launched by Elsevier in March 1997. Usage The journals are grouped into four main sections: *''Physical Sciences and Engineering'' *''Life Sciences'' *''Health Sciences'' *''Social Sciences and Humanities''. Article abstracts are freely available, and access to their full texts (in PDF and, for newer publications, also HTML) generally requires a subscription or pay-per-view purchase unless the content is freely available in open access. Papers published under several open access licenses are available on ScienceDirect without cost. Access to t ...

Snorkeling
Snorkeling (American and British English spelling differences#Doubled in British English, British and Commonwealth English spelling: snorkelling) is the practice of human swimming, swimming face down on or through a body of water while breathing the ambient air through a shaped tube called a Snorkel (swimming), snorkel, usually with swimming goggles or a diving mask, and swimfins. In cooler waters, a wetsuit may also be worn. The snorkel may be an independent item or integrated with the mask. The use of this equipment allows the snorkeler to observe the underwater environment for extended periods with relatively little effort, and to breathe while face-down at the surface. Snorkeling is a popular recreational activity, particularly at tropics, tropical resort locations. It provides the opportunity to observe marine biology#Lifeforms, underwater life in a natural setting without the complicated equipment and training required for scuba diving. It appeals to all ages because of ho ...

Ballast
Ballast is dense material used as a weight to provide stability to a vehicle or structure. Ballast, other than cargo, may be placed in a vehicle, often a ship or the gondola of a balloon or airship, to provide stability. A compartment within a boat, ship, submarine, or other floating structure that holds water is called a ballast tank. Water should be moved in and out from the ballast tank to balance the ship. In a vessel that travels on the water, the ballast will be kept below the water level, to counteract the effects of weight above the water level. The ballast may be redistributed in the vessel or disposed of altogether to change its effects on the movement of the vessel. History The basic concept behind the ballast tank can be seen in many forms of aquatic life, such as the blowfish or members of the argonaut group of octopus. The concept has been invented and reinvented many times by humans to serve a variety of purposes. In the fifteenth and sixteenth century, the ...

Eviota Filamentosa
''Eviota'' is a genus of fish in the family (biology), family Gobiidae, commonly as dwarfgobies found in the Indian Ocean, Indo-Pacific Ocean, Pacific region, where it is range (biology), distributed from Japan to Australia and from Africa to Pitcairn Island. Species are mainly associated with coral reefs. Many of these fish are short-lived, with Biological life cycle, life cycles as brief as 3.5 weeks in the tropics. Some species are hermaphrodites and some representatives live symbiotically among the tentacles of the mushroom coral.Bos, A.R.

Gobiodon Erythrospilus
''Gobiodon'' is a genus of gobies also known as coral gobies or "clown gobies" (which can also mean the related genus '' Microgobius''). Unlike the rest of the family Gobiidae, coral gobies, are not burrowers, instead they inhabit the branches of ''Acropora'' or similar hard corals. As a group, they are small, most ranging about 6 cm, with exceptions. They have a fusiform shape. ''Gobiodon burdigalicus'' from the Burdigalian (Miocene) of southwestern India is the first fossil (otoliths) record of this genus. Species Accepted species in this genus include: * '' Gobiodon acicularis'' Harold & R. Winterbottom, 1995 (Needlespine coral goby) * '' Gobiodon albofasciatus'' Sawada & R. Arai, 1972 (Whitelined coral goby) * '' Gobiodon aoyagii'' Shibukawa, T. Suzuki & Aizawa, 2013Shibukawa, K., Suzuki, T. & Aizawa, M.
