Redspotted Catshark
The redspotted catshark (''Schroederichthys chilensis''), also known as the Chilean catshark, is a species of catshark commonly found in the coastal waters of the southeastern Pacific, from central Peru to southern Chile. They are typically found in the rocky sublittoral areas at the edge of the continental shelf, in waters down to 100 m in depth. They spend the spring, summer, and fall in rocky subtidal areas, but winter in deeper offshore waters due to the strong currents at that time of year. Description Redspotted catsharks range in length from 30 to 66 cm, although these sizes are taken from captured sharks, and it is believed that they may grow larger than this. Their bodies are elongate and sleek, typical of the catshark family. Their dorsal side is a dark reddish brown with dark saddle patterns on their side. Their ventral sides are a creamy white with reddish spots. Redspotted catsharks have two dorsal fins, with the first dorsal axil over the pelvic region. ...

Lizard Catshark
The lizard catshark (''Schroederichthys saurisqualus'') is a small shark species of the catshark family, Scyliorhinidae, found off the coast of southern Brazil on the upper continental shelf at depths of between . Description The lizard catshark is a small species growing to a maximum size of for males and for females.

William Charles Schroeder
William Charles Schroeder (1895–1977) was an American ichthyologist. He was born on Staten Island, New York. He, along with his lifelong colleague Henry Bryant Bigelow, made substantial contributions to the knowledge of the fish fauna of the western North Atlantic. The two described 42 new species of jawless fishes and cartilaginous fishes, and authored several seminal publications, including ''Fishes of the Western North Atlantic'' and ''Fishes of the Gulf of Maine''.

Stewart Springer
Stewart Springer (5 June 190623 August 1991) was an American ichthyologist and herpetologist. He was an expert on shark behavior, classification (taxonomy), and population distribution. More than 35 species of sharks, skates, rays, and other creatures are either classified by or named after him. Education Springer was a field naturalist, mostly self-taught. In 1964, 35 years after he dropped out of Butler University, Springer obtained a baccalaureate from George Washington University after having already achieved success in his chosen field of ichthyology. His interest in animal behavior was apparent early in his life, when at age 22, he identified and described a new species of lizard, '' Cnemidophorus velox'', the plateau striped whiptail. His interest in the whiptail was piqued, he said, by the fact that he was chaperoning a field trip with the Cottonwood Gulch Foundation in Arizona in 1928. His young team of Boy Scouts could catch jack rabbits and other lizards in the are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shark Genera
Sharks are a group of elasmobranch cartilaginous fish characterized by a ribless endoskeleton, dermal denticles, five to seven gill slits on each side, and pectoral fins that are not fused to the head. Modern sharks are classified within the division Selachii and are the sister group to the Batomorphi ( rays and skates). Some sources extend the term "shark" as an informal category including extinct members of Chondrichthyes (cartilaginous fish) with a shark-like morphology, such as hybodonts. Shark-like chondrichthyans such as ''Cladoselache'' and ''Doliodus'' first appeared in the Devonian Period (419–359 million years), though some fossilized chondrichthyan-like scales are as old as the Ordovician, Late Ordovician (458–444 million years ago). The earliest confirmed modern sharks (Selachii) are known from the Early Jurassic around , with the oldest known member being ''Agaleus'', though records of true sharks may extend back as far as the Permian.

Alphone Guichenot
Antoine Alphonse Guichenot (31 July 1809 in Paris Р17 February 1876 in Cluny) was a French zoology, zoologist who taught, researched, and participated in specimen collecting trips on behalf of the ''Mus̩um national d'histoire naturelle'' (Paris), including an extensive biological survey of Algeria. His primary fields of research included fish and reptiles. He is credited with describing the ichthyological genera ''Agonomalus'', ''Neosebastes'' (gurnard scorpionfishes) and ''Glossanodon''. He also described numerous new species, including the New Caledonian Crested Gecko, New Caledonian crested gecko, ''Correlophus ciliatis'' (changed to ''Rhacodactylus ciliatus'' in 1994, but reclassified as ''Correlophus ciliatis'' in 2012). He retired to solely an assistant naturalist position in 1856, and died in 1876 in Cluny, France. Tribute Several fish species commemorate his name, an example being ''Paracanthobrama guichenoti'' Pieter Bleeker, Bleeker, 1864. He is also commemorat ...
