Description
Young Atlantic goliath grouper may live in brackish estuaries, canals, and mangrove swamps, unusual behavior among groupers.
They may reach extremely large sizes, growing to lengths of 8.2 feet (2.5 m) and can weigh as much as 800 pounds (363 kg). The world record for a hook and line-captured specimen is 680 pounds (309 kg), caught off Fernandina Beach, Florida, in 1961. They are usually around 400 pounds when mature. Considered of fine food quality, Atlantic goliath grouper were a highly sought-after quarry for fishermen. The grouper's inquisitive and generally fearless nature makes it a relatively easy prey for spear fishermen. They also tend to spawn in large aggregations, returning like clockwork to the same locations, making them particularly vulnerable to mass harvesting. Until a harvest ban was placed on the species, its population was in rapid decline. The fish is entirely protected from harvest and is recognized as a critically endangered species by the World Conservation Union (IUCN). The US began protection in 1990, and the Caribbean in 1993. The species' population has been recovering since the ban; with the fish's slow growth rate, however, it will take some time for populations to return to their previous levels. However, many conservationists are concerned that size-selective harvesting (seeking large fish and throwing back the small ones) may have inadvertently selected for smaller size, and fish of the size encountered so often in the mid-20th century may be lost forever.
Goliath grouper eat crustaceans, other fish, octopuses and young sea turtles. Grouper are preyed upon by large fish, such as barracudas, moray eels and large sharks.

Famous quotes containing the word description:
“Why does philosophy use concepts and why does faith use symbols if both try to express the same ultimate? The answer, of course, is that the relation to the ultimate is not the same in each case. The philosophical relation is in principle a detached description of the basic structure in which the ultimate manifests itself. The relation of faith is in principle an involved expression of concern about the meaning of the ultimate for the faithful.”
—Paul Tillich (1886–1965)
“Once a child has demonstrated his capacity for independent functioning in any area, his lapses into dependent behavior, even though temporary, make the mother feel that she is being taken advantage of....What only yesterday was a description of the child’s stage in life has become an indictment, a judgment.”
—Elaine Heffner (20th century)
“Everything to which we concede existence is a posit from the standpoint of a description of the theory-building process, and simultaneously real from the standpoint of the theory that is being built. Nor let us look down on the standpoint of the theory as make-believe; for we can never do better than occupy the standpoint of some theory or other, the best we can muster at the time.”
—Willard Van Orman Quine (b. 1908)
