Astroscopus Guttatus
''Astroscopus guttatus'' (northern stargazer) is a fish that can reach lengths of and is found on the Atlantic shores between the states of North Carolina and New York in the United States. The northern stargazer can be found up to depths of . Stargazers have a flat forehead with a lot of body mass up front near the mouth. Description The northern stargazer has a blackish brown body with white spots that are of the same size all over its head and back. It has three dark horizontal stripes on its (white) tail. The mouth of the stargazer faces up so that it can ambush prey while hiding in the sandy bottoms of coastal bodies of water. The top of the stargazer has electric organs in the orbitae which can generate and transmit an electric shock. The electric apparatus is composed of two organs, which form two vertical columns roughly oval in horizontal section, and placed behind and somewhat under each eye. It is composed of about 200 thin layers of electric tissue. Ecology Norther ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charles Conrad Abbott
Charles Conrad Abbott (June 4, 1843 – July 27, 1919) was an American archaeologist and naturalist. Biography Abbott was born at Trenton, New Jersey, son of Timothy and Susan (Conrad) Abbott; grandson of Joseph and Anne (Rickey) Abbott, and a descendant of John and Anne (Mauleverer) Abbott, settlers, from England, in New Jersey in 1684. He studied medicine at the University of Pennsylvania School of Medicine. During the American Civil War, he served as a surgeon in the Union Army. He received his M.D. degree from University of Pennsylvania in 1865, but never entered into the practice of the profession. In 1876, he announced the discovery, later confirmed by other archaeologists, of traces of human presence in the Delaware River Valley dating from the first or "Kansan" ice age, and inferentially from the pre-glacial period when humans are believed to have entered upon the North American continent. However, today the consensus of archaeologists is that most of Abbott's "Trenton ... [...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 ...
