Charles Eric Dawson
Charles Eric "Chuck" Dawson (December 6, 1922 – February 11, 1993) was a Canadian-American ecologist Ecology () is the study of the relationships between living organisms, including humans, and their physical environment. Ecology considers organisms at the individual, population, community, ecosystem, and biosphere level. Ecology overlaps wi ..., ichthyology, ichthyologist, and taxonomy (biology), taxonomist. He held expertise in goby, gobies, flatfishes, and sand stargazers, and was considered "the ultimate authority" on pipefishes in the family Syngnathidae. Life Dawson was born in Vancouver, British Columbia, Canada, but would eventually spend much of his career at the University of Southern Mississippi's Gulf Coast Research Laboratory in Ocean Springs, Mississippi, where he worked early as an administrator, then researcher, and museum curator. Over his long career Dawson wrote 150 publications, on the majority of which he was the sole author. He recognized 52 Syngnat ...

Sand Stargazer
Sand stargazers are blennioids; perciform marine fish of the family Dactyloscopidae. Found in temperate to tropical waters of North and South America; some may also inhabit brackish environments. The giant sand stargazer (''Dactylagnus mundus'') is the largest at 15 cm in length; all other species are under 10 cm. These blennies are named well: sand stargazers have protruding eyes on the top of their heads, fixed in an upward gaze, and may be on stalks. Their large mouths are also upturned. The dorsal fin is long and may or may not be continuous, with seven to 23 spines; the pelvic fins are situated below the throat and possess one spine. The anal fin is equally long and flowing. The mouth is fringed, and like the upper edge of the operculum (the gill cover), this fringe is divided into finger-like structures. The body is greatly elongated, and coloration is generally drab. As their name would suggest, sand stargazers spend most of their time buried in sandy substrat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bahamas
The Bahamas (), officially the Commonwealth of The Bahamas, is an island country within the Lucayan Archipelago of the West Indies in the Atlantic Ocean, North Atlantic. It takes up 97% of the Lucayan Archipelago's land area and is home to 88% of the archipelago's population. The archipelagic state consists of more than 3,000 islands, cays, and islets in the Atlantic Ocean, and is located north of Cuba and northwest of the island of Hispaniola (split between the Dominican Republic and Haiti) and the Turks and Caicos Islands, southeast of the U.S. state of Florida, and east of the Florida Keys. The capital is Nassau, Bahamas, Nassau on the island of New Providence. The Royal Bahamas Defence Force describes The Bahamas' territory as encompassing of ocean space. The Bahama Islands were inhabited by the Lucayan people, Lucayans, a branch of the Arawakan-Taino language, speaking Taíno, for many centuries. Christopher Columbus was the first European to see the islands, making hi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Virgin Islands
The Virgin Islands ( es, Islas Vírgenes) are an archipelago in the Caribbean Sea. They are geologically and biogeographically the easternmost part of the Greater Antilles, the northern islands belonging to the Puerto Rico Trench and St. Croix being a displaced part of the same geologic structure. Politically, the British Virgin Islands have been governed as the western island group of the Leeward Islands, which are the northern part of the Lesser Antilles, and form the border between the Caribbean Sea and the Atlantic Ocean. The archipelago is separated from the true Lesser Antilles by the Anegada Passage and from the main island of Puerto Rico by the Virgin Passage. The islands fall into three different political jurisdictions: * Virgin Islands, informally referred to as British Virgin Islands, a British overseas territory, * Virgin Islands of the United States, an unincorporated territory of the United States, * Spanish Virgin Islands, the easternmost islands of the Comm ...

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 (sharks and rays), as well as some other fishes. Total length meas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fish Described In 1982
Fish are aquatic, craniate, gill-bearing animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Approximately 95% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with around 99% of those being teleosts. The earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Cambrian period. Although they lacked a true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts. Fish would continue to evolve through the Paleozoic era, diversifying into a wide variety of forms. Many fish of the Paleozoic developed external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) became formidable marine predators rather than just the prey of arthropods. Most f ...
