Pentacerotidae
Pentacerotidae or armourheads are a small family of ray-finned fishes in the order Acropomatiformes. They are native to the Indian Ocean, western and central Pacific, and southwestern Atlantic. They are generally found at rocky reefs below normal scuba diving depths, although several species occur in low densities at shallower depths. Their name, from Greek ''pente'' meaning "five" and ''keras'' meaning "horn", refers to the prominent, sharp spines in their dorsal fins (though these do not number five in all species). The largest species in the family (''Paristiopterus'') may reach a length of . Many species have distinct dark-and-light-striped bodies, while others are overall dusky-silvery.

Acropomatiformes
The Acropomatiformes or Pempheriformes are an order of fish from the group of perch relatives Percomorpha. The relationship of the families assigned to the Acropomatiformes is based on molecular biological studies and is not yet supported by morphological characteristics. The giant sea bass (''Stereolepis gigas'') of the Eastern Pacific Ocean, with a maximum length of and weight of , is the largest species of the Pempheriformes. As early as 2007, Smith and Craig established a relationship between the wreckfish Polyprionidae, the longfin pike Dinolestes lewini, the armored heads Pentacerotidae and the lanternbellies Acropomatidae. In February 2009, Blaise Li and colleagues described a monophyletic clade composed of the Howellidae, the Lateolabracidae and the deep-sea cardinalfishes Epigonidae in their analysis of the relationships between the various groups of the Acanthomorpha. In a revision of the bony fish systematics published in early 2013 by Ricardo Betancur-R. and c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Scuba Diving
Scuba diving is a Diving mode, mode of underwater diving whereby divers use Scuba set, breathing equipment that is completely independent of a surface breathing gas supply, and therefore has a limited but variable endurance. The word ''scuba'' is an Acronym#Normal case and acronyms, acronym for "Self-Contained Underwater Breathing Apparatus" and was coined by Christian J. Lambertsen in a patent submitted in 1952. Scuba divers carry their own source of breathing gas, affording them greater independence and movement than surface-supplied divers, and more time underwater than freedivers. Although the use of compressed air is common, other gas blends are also used. Open-circuit scuba systems discharge the breathing gas into the environment as it is exhaled and consist of one or more diving cylinders containing breathing gas at high pressure which is supplied to the diver at ambient pressure through a diving regulator. They may include additional cylinders for range extension, de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atlantic
The Atlantic Ocean is the second largest of the world's five oceanic divisions, with an area of about . It covers approximately 17% of Earth's surface and about 24% of its water surface area. During the Age of Discovery, it was known for separating the New World of the Americas (North America and South America) from the Old World of Afro-Eurasia (Africa, Asia, and Europe). Through its separation of Afro-Eurasia from the Americas, the Atlantic Ocean has played a central role in the development of human society, globalization, and the histories of many nations. While the Norse were the first known humans to cross the Atlantic, it was the expedition of Christopher Columbus in 1492 that proved to be the most consequential. Columbus's expedition ushered in an age of exploration and colonization of the Americas by European powers, most notably Portugal, Spain, France, and the United Kingdom. From the 16th to 19th centuries, the Atlantic Ocean was the center of both an eponymou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Family (biology)
Family (, : ) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". The delineation of what constitutes a family—or whether a described family should be acknowledged—is established and decided upon by active taxonomists. There are not strict regulations for outlining or acknowledging a family, yet in the realm of plants, these classifications often rely on both the vegetative and reproductive characteristics of plant species. Taxonomists frequently hold varying perspectives on these descriptions, leading to a lack of widespread consensus within the scientific community ...
