Giant Grouper
The giant grouper (''Epinephelus lanceolatus''), also known as the Queensland grouper, brindle grouper or mottled-brown sea bass, is a species of marine ray-finned fish, a grouper from the subfamily Epinephelinae which is part of the family Serranidae, which also includes the anthias and sea basses. It has a wide Indo-Pacific distribution and is one of the largest extant species of bony fish. Description The giant grouper has a robust body which has a standard length equivalent to 2.4 to 3.4 times its depth. The dorsal profile of the head and the intraorbital area are convex, The propercle has a rounded corner and a finely serrated margin. The gill cover has a convex upper margin. There are 11 spines and 14-16 soft rays in the dorsal fin while the anal fin has 3 spines and 8 soft rays. The caudal fin is slightly rounded. There are 54 to 62 scales in its lateral line. The adults are grayish-brown in colour overlain with a mottled pattern and with darker fins. The small juvenile ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fish Measurement
Fish measurement is the measuring of individual fish and various parts of their anatomies. These data are used in many areas of ichthyology, including taxonomy and fisheries biology. Overall length * Standard length (SL) is the length of a fish measured from the tip of the snout to the posterior end of the last vertebra or to the posterior end of the midlateral portion of the hypural plate. Simply put, this measurement excludes the length of the caudal (tail) fin. * Total length (TL) is the length of a fish measured from the tip of the snout to the tip of the longer lobe of the caudal fin, usually measured with the lobes compressed along the midline. It is a straight-line measure, not measured over the curve of the body. Standard length measurements are used with Teleostei (most bony fish), while total length measurements are used with Myxini ( hagfish), Petromyzontiformes ( lampreys), and (usually) Elasmobranchii (shark Sharks are a group of elasmobranch fish characte ...

Christmas Island
Christmas Island, officially the Territory of Christmas Island, is an Australian external territory comprising the island of the same name. It is located in the Indian Ocean, around south of Java and Sumatra and around north-west of the closest point on the Australian mainland. It lies northwest of Perth and south of Singapore. It has an area of . Christmas Island had a population of 1,692 residents , the majority living in settlements on the northern edge of the island. The main settlement is Flying Fish Cove. Historically, Asian Australians of Chinese, Malay, and Indian descent formed the majority of the population. Today, around two-thirds of the island's population is estimated to have Straits Chinese origin (though just 22.2% of the population declared a Chinese ancestry in 2021), with significant numbers of Malays and European Australians and smaller numbers of Straits Indians and Eurasians. Several languages are in use, including English, Malay, and various C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Western Australia
Western Australia (commonly abbreviated as WA) is a state of Australia occupying the western percent of the land area of Australia excluding external territories. It is bounded by the Indian Ocean to the north and west, the Southern Ocean to the south, the Northern Territory to the north-east, and South Australia to the south-east. Western Australia is Australia's largest state, with a total land area of . It is the List of country subdivisions by area, second-largest country subdivision in the world, surpassed only by Russia's Sakha, Sakha Republic. the state has 2.76 million inhabitants percent of the national total. The vast majority (92 percent) live in the South-West Land Division, south-west corner; 79 percent of the population lives in the Perth area, leaving the remainder of the state sparsely populated.

Rottnest Island
Rottnest Island ( nys, Wadjemup), often colloquially referred to as "Rotto", is a island off the coast of Western Australia, located west of Fremantle. A sandy, low-lying island formed on a base of aeolianite limestone, Rottnest is an A-class reserve, the highest level of protection afforded to public land. Together with Garden Island, Rottnest Island is a remnant of Pleistocene dune ridges. Along with several other islands, Rottnest became separated from the mainland around 7,000 years ago, when sea levels rose; the traditional Noongar name for the island is ''Wadjemup'', which means "place across the water where the spirits are". Human artefacts have been found on the island dating back at least 30,000 years, but visitation and habitation of the island by the Noongar people appears to have ceased following its separation from the mainland. The island was first documented by Willem de Vlamingh in 1696, who called it t Eylandt 't Rottenest'' ("Rats' Nest Island") after the ...

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 area a ...

Pitcairn Islands
The Pitcairn Islands (; Pitkern: '), officially the Pitcairn, Henderson, Ducie and Oeno Islands, is a group of four volcanic islands in the southern Pacific Ocean that form the sole British Overseas Territory in the Pacific Ocean. The four islands—Pitcairn, Henderson, Ducie and Oeno—are scattered across several hundred miles of ocean and have a combined land area of about . Henderson Island accounts for 86% of the land area, but only Pitcairn Island is inhabited. The islands nearest to the Pitcairn Islands are Mangareva (of French Polynesia) at 688 km to the west and Easter Island at 1,929 km to the east. The Pitcairn Islanders are a biracial ethnic group descended mostly from nine ''Bounty'' mutineers and a handful of Tahitian consorts—as is still apparent from the surnames of many of the islanders. The mutiny and its aftermath have been the subject of many books and films. As of January 2020, the territory had only 47 permanent inhabitants. History Polyn ...

Western Pacific Ocean
The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south, and is bounded by the continents of Asia and Oceania in the west and the Americas in the east. At in area (as defined with a southern Antarctic border), this largest division of the World Ocean—and, in turn, the hydrosphere—covers about 46% of Earth's water surface and about 32% of its total surface area, larger than Earth's entire land area combined .Pacific Ocean .

Algoa Bay
Algoa Bay is a maritime bay in the Eastern Cape, South Africa. It is located in the east coast, east of the Cape of Good Hope. Algoa Bay is bounded in the west by Cape Recife and in the east by Cape Padrone. The bay is up to deep. The harbour city of Port Elizabeth is situated adjacent to the bay, as is the Port of Ngqura deep water port facility. History The Portuguese explorer Bartolomeu Dias was the first European to reach Algoa Bay in 1488, where he planted a wooden cross on a small island now called St Croix or Santa Cruz island. He gave the bay a name meaning "Bay of the Rock", which was changed in Portugal to ''Bahia de Lagoa'' or Bay of the Lagoon, and which eventually became Algoa Bay. Joshua Slocum talks about Algoa Bay in his book ' Sailing Alone Around the World' (this is not an historical account): Nautical charts of the bay caution mariners that "projectiles and badly corroded mustard gas containers have been found in the area between Cape St Francis and Bird ...

Lateral Line
The lateral line, also called the lateral line organ (LLO), is a system of sensory organs found in fish, used to detect movement, vibration, and pressure gradients in the surrounding water. The sensory ability is achieved via modified epithelial cells, known as hair cells, which respond to displacement caused by motion and transduce these signals into electrical impulses via excitatory synapses. Lateral lines serve an important role in schooling behavior, predation, and orientation. Fish can use their lateral line system to follow the vortices produced by fleeing prey. Lateral lines are usually visible as faint lines of pores running lengthwise down each side, from the vicinity of the gill covers to the base of the tail. In some species, the receptive organs of the lateral line have been modified to function as electroreceptors, which are organs used to detect electrical impulses, and as such, these systems remain closely linked.
