Ridley Sea Turtle
Ridley sea turtles are a genus (''Lepidochelys'') of sea turtle comprising two species: Kemp's ridley sea turtle and the olive ridley sea turtle. Kemp's ridley sea turtles are currently on the New York and United States lists of endangered species. Anatomy Adult ridley sea turtles grow to a length of , and weight of . They feed on crabs, fish, cephalopods, clams, and some marine vegetation. Etymology and taxonomic history The origin of "ridley" is a subject of speculation. Prior to being known as ridleys, French naturalist Bernard Germain de Lacépède referred to the ''Lepidochelys'' species as "bastard turtles." Renowned sea turtle conservationist Archie Carr claimed that "ridley" was a common Floridan term, quite possibly, a dialectic corruption of "riddle." Conservation The Kemp's ridley sea turtles were on the brink of extinction in the 1960s with low numbers of 200 nesting individuals. Due to strict laws that protected their nesting sites in Mexico and altered fish ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kemp's Ridley Sea Turtle
Kemp's ridley sea turtle (''Lepidochelys kempii''), also called the Atlantic ridley sea turtle, is the rarest species of sea turtle and is the world's most endangered species of sea turtle. It is one of two living species in the genus '' Lepidochelys'' (the other one being ''L. olivacea'', the olive ridley sea turtle). Taxonomy This species of turtle is called Kemp's ridley because Richard Moore Kemp (1825–1908) of Key West was the first to send a specimen to Samuel Garman at Harvard, but the origin of the name "ridley" itself is unknown. Prior to the term being popularly used (for both species in the genus), ''L. kempii'' at least was known as the "bastard turtle". At least one source also refers to Kemp's ridley as a "heartbreak turtle". In her book ''The Great Ridley Rescue'', Pamela Philips claimed the name was coined by fishermen who witnessed the turtles dying after being "turned turtle" (on their backs). The fishermen said the turtles "died of a broken heart". Descr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leopold Fitzinger
Leopold Joseph Franz Johann Fitzinger (13 April 1802 – 20 September 1884) was an Austrian zoologist. Fitzinger was born in Vienna and studied botany at the University of Vienna under Nikolaus Joseph von Jacquin. He worked at the Vienna Naturhistorisches Museum between 1817, when he joined as a volunteer assistant, and 1821, when he left to become secretary to the provincial legislature of Lower Austria; after a hiatus he was appointed assistant curator in 1844 and remained at the Naturhistorisches Museum until 1861. Later he became director of the zoos of Munich and Budapest. In 1826 he published ''Neue Classification der Reptilien'', based partly on the work of his friends Friedrich Wilhelm Hemprich and Heinrich Boie. In 1843 he published ''Systema Reptilium'', covering geckos, chameleons and iguanas. Fitzinger is commemorated in the scientific names of five reptiles: '' Algyroides fitzingeri'', '' Leptotyphlops fitzingeri'', '' Liolaemus fitzingerii'', ''Micrurus tener fitzi ...

Olive Ridley
The olive ridley sea turtle (''Lepidochelys olivacea''), also known commonly as the Pacific ridley sea turtle, is a species of turtle in the family Cheloniidae. The species is the second-smallest and most abundant of all sea turtles found in the world. ''L. olivacea'' is found in warm and tropical waters, primarily in the Pacific and Indian Oceans, but also in the warm waters of the Atlantic Ocean. This turtle and the related Kemp's ridley turtle are best known for their unique synchronised mass nestings called ''arribadas'', where thousands of females come together on the same beach to lay eggs. Taxonomy The olive ridley sea turtle may have been first described as ''Testudo mydas minor'' by Georg Adolf Suckow in 1798. It was later described and named ''Chelonia multiscutata'' by Heinrich Kuhl in 1820. Still later, it was described and named ''Chelonia olivacea'' by Johann Friedrich von Eschscholtz in 1829. The species was placed in the subgenus ''Lepidochelys'' by Leopold Fitz ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Crabs
Crabs are decapod crustaceans of the infraorder Brachyura, which typically have a very short projecting "tail" (abdomen) ( el, βραχύς , translit=brachys = short, / = tail), usually hidden entirely under the thorax. They live in all the world's oceans, in freshwater, and on land, are generally covered with a thick exoskeleton, and have a single pair of pincers. They first appeared during the Jurassic Period. Description Crabs are generally covered with a thick exoskeleton, composed primarily of highly mineralized chitin, and armed with a pair of chelae (claws). Crabs vary in size from the pea crab, a few millimeters wide, to the Japanese spider crab, with a leg span up to . Several other groups of crustaceans with similar appearances – such as king crabs and porcelain crabs – are not true crabs, but have evolved features similar to true crabs through a process known as carcinisation. Environment Crabs are found in all of the world's oceans, as well as in fresh w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fish
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. Mos ...

Cephalopods
A cephalopod is any member of the molluscan class Cephalopoda (Greek plural , ; "head-feet") such as a squid, octopus, cuttlefish, or nautilus. These exclusively marine animals are characterized by bilateral body symmetry, a prominent head, and a set of arms or tentacles (muscular hydrostats) modified from the primitive molluscan foot. Fishers sometimes call cephalopods "inkfish", referring to their common ability to squirt ink. The study of cephalopods is a branch of malacology known as teuthology. Cephalopods became dominant during the Ordovician period, represented by primitive nautiloids. The class now contains two, only distantly related, extant subclasses: Coleoidea, which includes octopuses, squid, and cuttlefish; and Nautiloidea, represented by ''Nautilus'' and ''Allonautilus''. In the Coleoidea, the molluscan shell has been internalized or is absent, whereas in the Nautiloidea, the external shell remains. About 800 living species of cephalopods have been identified. Tw ...

Bernard Germain De Lacépède
Bernard-Germain-Étienne de La Ville-sur-Illon, comte de Lacépède or La Cépède (; 26 December 17566 October 1825) was a French naturalist and an active freemason. He is known for his contribution to the Comte de Buffon's great work, the ''Histoire Naturelle''. Biography Lacépède was born at Agen in Guienne. His education was carefully conducted by his father, and the early perusal of Buffon's Natural History ('' Histoire naturelle, générale et particulière'') awakened his interest in that branch of study, which absorbed his chief attention. His leisure he devoted to music, in which, besides becoming a good performer on the piano and organ, he acquired considerable mastery of composition, two of his operas (which were never published) meeting with the high approval of Gluck; in 1781–1785 he also brought out in two volumes his ''Poétique de la musique''. Meantime he wrote two treatises, ''Essai sur l'électricité'' (1781) and ''Physique générale et particuliè ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Archie Carr
Archie Fairly Carr, Jr. (June 16, 1909 – May 21, 1987) was an American herpetologist, ecologist, and conservationist. He was a Professor of Zoology at the University of Florida and an acclaimed writer on science and nature. He brought attention to the world's declining sea turtle populations due to over-exploitation and habitat loss. Wildlife refuges in Florida and Costa Rica have been named in his honor. Biography Born in Mobile, Alabama, to a Presbyterian pastor, Carr grew up in Mobile, Fort Worth, Texas, and Savannah, Georgia. He studied zoology at the University of Florida (UF), eventually specializing in herpetology. He further refined that interest to the study of turtles and eventually became one of the world's foremost authorities on sea turtles. He married Marjorie Harris Carr, a conservationist herself. While a student at UF, he became a member of the Pi Kappa Phi fraternity. From UF, he received bachelor's degree in 1932, M.S. in 1934, and Ph.D. in 1937. He was a ...

Fishing Tackle
Fishing tackle is the equipment used by anglers when fishing. Almost any equipment or gear used in fishing can be called fishing tackle, examples being hooks, lines, baits/ lures, rods, reels, floats, sinkers/ feeders, nets, stringers/ keepnets/ livewells, spears, gaffs, traps, waders and tackle boxes, as well as any wire, snaps, beads, spoons, blades, spinners, clevises and tools that make it easy to tie knots. Gear that is attached to the end of a fishing line (and thus get cast out along with the bait) is collectively called terminal tackles, which include hooks, leaders, floats, sinkers/feeders, swivels and any attached snaps and/or split rings. Sometimes the term " rig" is used for a routine assembly of terminal tackle combination. Fishing tackle can be contrasted with fishing techniques. Fishing tackle refers to the physical equipment that is used when fishing, whereas fishing techniques refers to the manner in which the tackle is used (or "presented") when ...
