Spadefish
Ephippidae is a family containing the spadefishes, with about eight genera and a total of 20 marine species. Well-known species include the Atlantic spadefish (''Chaetodipterus faber'') and the reef-dwelling genus ''Platax'', the batfishes, which are kept as aquarium fish. They are spade-shaped and laterally compressed, and have very symmetrical, triangular dorsal and anal fins. They are shiny silver with areas of yellow and vertical brown or black banding. The eyes are often located in one of the vertical bands as a method of camouflage. Scuba divers sometimes mistake them for angelfish, which are similar in shape, but not closely related. Other genera in the family are characterized by long, trailing, pointed dorsal and anal fins. Most species feed primarily on algae and small invertebrates. Some spadefishes are popular sport fishing catches. The Atlantic spadefish (''Chaetodipterus faber''), for example, is a black and white striped fish common just offshore in the southeaste ...

Atlantic Spadefish
The Atlantic spadefish (''Chaetodipterus faber'') is a species of marine fish belonging to the family Ephippidae. It is the symbol of the North Carolina Aquariums. Taxonomy and etymology The scientific name is derived from the Greek word "chaíti" meaning "mane" and "dipteros" meaning "with two fins." The Atlantic spadefish belongs to the genus '' Chaetodipterus'', which includes two other species: the West African spadefish (''Chaetodipterus lippei'') and the Pacific spadefish (''Chaetodipterus zonatus''). The genus ''Chaetodipterus'' belongs to the family Ephippidae, which includes spadefish and batfish. ''Chaetodipterus faber'' is known by numerous other colloquial names, including angelfish, white angelfish, threetailed porgy, ocean cobbler, and moonfish. Description The disk-shaped body is very deep and compressed, and the snout is blunt. There are 9 dorsal spines and 21-24 soft dorsal rays, and there are 3 anal spines and 17-19 anal rays. The second dorsal and ana ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Exellia
''Exellia'' is a genus of extinct spadefish that lived in the Tethys Ocean during the early Paleogene. The adult form is shaped akin to a large spadefish or a short dolphinfish, with very large pelvic fins, and a long dorsal fin starting from in front of the eyes to near the base of the caudal peduncle. The juvenile form resembles a juvenile drumfish, with the dorsal fin forming a long crest on top of the head. The earlier species, ''E. proxima'', is known from the Danata Formation Lagerstätten from the Late Paleocene of Turkmenistan. The latter-occurring species, ''E. velifer'', is the better studied species, and is known from numerous adult and juvenile specimens from the Middle Eocene Monte Bolca Lagerstätten. Most researchers regard ''Exellia'' as a spadefish, though, some remove this genus, and the related '' Eoluvarus'' to a separate family Family (from la, familia) is a group of people related either by consanguinity (by recognized birth) or affinity (by m ...

Great Barrier Reef
The Great Barrier Reef is the world's largest coral reef system composed of over 2,900 individual reefs and 900 islands stretching for over over an area of approximately . The reef is located in the Coral Sea, off the coast of Queensland, Australia, separated from the coast by a channel 100 miles wide in places and over 200 feet deep. The Great Barrier Reef can be seen from outer space and is the world's biggest single structure made by living organisms. This reef structure is composed of and built by billions of tiny organisms, known as coral polyps. It supports a wide diversity of life and was selected as a World Heritage Site in 1981. CNN labelled it one of the seven natural wonders of the world in 1997. Australian World Heritage places included it in its list in 2007. The Queensland National Trust named it a state icon of Queensland in 2006. A large part of the reef is protected by the Great Barrier Reef Marine Park, which helps to limit the impact of human use, suc ...

Seaweed
Seaweed, or macroalgae, refers to thousands of species of macroscopic, multicellular, marine algae. The term includes some types of ''Rhodophyta'' (red), ''Phaeophyta'' (brown) and ''Chlorophyta'' (green) macroalgae. Seaweed species such as kelps provide essential nursery habitat for fisheries and other marine species and thus protect food sources; other species, such as planktonic algae, play a vital role in capturing carbon, producing at least 50% of Earth's oxygen. Natural seaweed ecosystems are sometimes under threat from human activity. For example, mechanical dredging of kelp destroys the resource and dependent fisheries. Other forces also threaten some seaweed ecosystems; a wasting disease in predators of purple urchins has led to a urchin population surge which destroyed large kelp forest regions off the coast of California. Humans have a long history of cultivating seaweeds for their uses. In recent years, seaweed farming has become a global agricultural practice, p ...

Parrotfish
Parrotfishes are a group of about 90 fish species regarded as a family (Scaridae), or a subfamily (Scarinae) of the wrasses. With about 95 species, this group's largest species richness is in the Indo-Pacific. They are found in coral reefs, rocky coasts, and seagrass beds, and can play a significant role in bioerosion. Description Parrotfish are named for their dentition, which is distinct from other fish, including other labrids. Their numerous teeth are arranged in a tightly packed mosaic on the external surface of their jaw bones, forming a parrot-like beak with which they rasp algae from coral and other rocky substrates (which contributes to the process of bioerosion). Maximum sizes vary within the family, with the majority of species reaching in length. However, a few species reach lengths in excess of , and the green humphead parrotfish can reach up to . The smallest species is the bluelip parrotfish (''Cryptotomus roseus''), which has a maximum size of . Mucus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paleocene
The Paleocene, ( ) or Palaeocene, is a geological epoch that lasted from about 66 to 56 million years ago (mya). It is the first epoch of the Paleogene Period in the modern Cenozoic Era. The name is a combination of the Ancient Greek ''palaiós'' meaning "old" and the Eocene Epoch (which succeeds the Paleocene), translating to "the old part of the Eocene". The epoch is bracketed by two major events in Earth's history. The K–Pg extinction event, brought on by an asteroid impact and possibly volcanism, marked the beginning of the Paleocene and killed off 75% of living species, most famously the non-avian dinosaurs. The end of the epoch was marked by the Paleocene–Eocene Thermal Maximum (PETM), which was a major climatic event wherein about 2,500–4,500 gigatons of carbon were released into the atmosphere and ocean systems, causing a spike in global temperatures and ocean acidification. In the Paleocene, the continents of the Northern Hemisphere were still connected v ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Surgeonfish
Acanthuridae are the family of surgeonfishes, tangs, and unicornfishes. The family includes about 86 extant species of marine fish living in tropical seas, usually around coral reefs. Many of the species are brightly colored and popular in aquaria. Morphology The distinctive characteristic of the family is that they have scalpel-like modified scales, one or more on either side of the peduncle of the tail. The spines are dangerously sharp and may seriously injure anyone who carelessly handles such a fish. The dorsal, anal, and caudal fins are large, extending for most of the length of the body. The mouths are small and have a single row of teeth adapted to grazing on algae. Surgeonfishes sometimes feed as solitary individuals, but they often travel and feed in schools. Feeding in schools may be a mechanism for overwhelming the highly aggressive defense responses of small territorial damselfishes that vigorously guard small patches of algae on coral reefs.
