Chaetodon Adiergastos
The Philippine butterflyfish (''Chaetodon adiergastos''), the Bantayan butterflyfish or panda butterflyfish,, is a species of marine ray-finned fish, a butterflyfish belonging to the family Chaetodontidae. It is found in the western Pacific, from the Ryukyu Islands and Taiwan to Java and northwestern Australia. It grows to a maximum length of 20 cm (nearly 8 in). The body is white with diagonal brown stripes on the sides. The dorsal, caudal, anal and pelvic fins are yellow. There are rounded broad black bands on the face, covering the eye, but not continuous from one side of the body to the other but with a separate black spot centered on the forehead. The Philippine butterflyfish was first formally described in 1910 by the American ichthyologist Alvin Seale (1871-1958) with the type locality given as Bantayan Island in the Philippines. It belongs to the large subgenus ''Rabdophorus'' which might warrant recognition as a distinct genus. In this group, it appears to bel ...

Alvin Seale
Alvin Seale (July 8, 1871 – July 28, 1958) was a naturalist known for his aquarium design and as an ichthyologist. Early life Alvin Seale was born on July 8, 1871, in Fairmount, Indiana, to a family of Quakers. In 1892, he attended Stanford University, and was tutored by David Starr Jordan. Education In 1896, the year that Seale would have graduated from Stanford in zoology, he was picked by Professor Jordan, along with fellow student Norman B. Scofield, to go to Point Barrow in Alaska. His mission was to look for salmon in the Mackenzie River. Travels Before returning to Stanford Seale collected sea birds along the Alaskan coast on behalf of the British Museum. He also went with his roommate to the Klondike to join the gold rush there. According to Seale, his companion “struck it rich.” Seale, however, was too busy exploring the native wildlife to waste his time searching for gold. In his unpublished diary Seale writes that he spent “an exciting year." Polynesian c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ichthyologist
Ichthyology is the branch of zoology devoted to the study of fish, including bony fish ( Osteichthyes), cartilaginous fish (Chondrichthyes), and jawless fish (Agnatha). According to FishBase, 33,400 species of fish had been described as of October 2016, with approximately 250 new species described each year. Etymology The word is derived from the Greek words ἰχθύς, ''ikhthus'', meaning "fish"; and λογία, ''logia'', meaning "to study". History The study of fish dates from the Upper Paleolithic Revolution (with the advent of "high culture"). The science of ichthyology was developed in several interconnecting epochs, each with various significant advancements. The study of fish receives its origins from humans' desire to feed, clothe, and equip themselves with useful implements. According to Michael Barton, a prominent ichthyologist and professor at Centre College, "the earliest ichthyologists were ''hunters and gatherers'' who had learned how to obtain the most usef ...

Estuaries
An estuary is a partially enclosed coastal body of brackish water with one or more rivers or streams flowing into it, and with a free connection to the open sea. Estuaries form a transition zone between river environments and maritime environments and are an example of an ecotone. Estuaries are subject both to marine influences such as tides, waves, and the influx of saline water, and to fluvial influences such as flows of freshwater and sediment. The mixing of seawater and freshwater provides high levels of nutrients both in the water column and in sediment, making estuaries among the most productive natural habitats in the world. Most existing estuaries formed during the Holocene epoch with the flooding of river-eroded or glacially scoured valleys when the sea level began to rise about 10,000–12,000 years ago. Estuaries are typically classified according to their geomorphological features or to water-circulation patterns. They can have many different names, such as bays, har ...

Soft Coral
Alcyonacea, or soft corals, are an order of corals. In addition to the fleshy soft corals, the order Alcyonacea now contains all species previously known as "gorgonian corals", that produce a more or less hard skeleton, though quite different from "true" corals (Scleractinia). These can be found in suborders Holaxonia, Scleraxonia, and Stolonifera. They are Sessility (zoology), sessile colony (biology), colonial cnidarians that are found throughout the oceans of the world, especially in the deep sea, polar waters, tropics and subtropics. Common names for subsets of this order are sea fans and sea whips; others are similar to the sea pens of related order Pennatulacea. Individual tiny polyp (zoology), polyps form colonies that are normally erect, flattened, branching, and reminiscent of a fan (implement), fan. Others may be whiplike, bushy, or even encrusting. A colony can be several feet high and across, but only a few inches thick. They may be brightly coloured, often purple, r ...

Coral Reef
A coral reef is an underwater ecosystem characterized by reef-building corals. Reefs are formed of colonies of coral polyps held together by calcium carbonate. Most coral reefs are built from stony corals, whose polyps cluster in groups. Coral belongs to the class Anthozoa in the animal phylum Cnidaria, which includes sea anemones and jellyfish. Unlike sea anemones, corals secrete hard carbonate exoskeletons that support and protect the coral. Most reefs grow best in warm, shallow, clear, sunny and agitated water. Coral reefs first appeared 485 million years ago, at the dawn of the Early Ordovician, displacing the microbial and sponge reefs of the Cambrian. Sometimes called ''rainforests of the sea'', shallow coral reefs form some of Earth's most diverse ecosystems. They occupy less than 0.1% of the world's ocean area, about half the area of France, yet they provide a home for at least 25% of all marine species, including fish, mollusks, worms, crustaceans, echinoderms, sp ...

Raccoon
The raccoon ( or , ''Procyon lotor''), sometimes called the common raccoon to distinguish it from other species, is a mammal native to North America. It is the largest of the procyonid family, having a body length of , and a body weight of . Its grayish coat mostly consists of dense underfur, which insulates it against cold weather. Three of the raccoon's most distinctive features are its extremely dexterous front paws, its facial mask, and its ringed tail, which are themes in the mythologies of the indigenous peoples of the Americas relating to the animal. The raccoon is noted for its intelligence, as studies show that it is able to remember the solution to tasks for at least three years. It is usually nocturnal and omnivorous, eating about 40% invertebrates, 33% plants, and 27% vertebrates. The original habitats of the raccoon are deciduous and mixed forests, but due to their adaptability, they have extended their range to mountainous areas, coastal marshes, and urban ...

Raccoon Butterflyfish
The raccoon butterflyfish (''Chaetodon lunula''), also known as the crescent-masked butterflyfish, lunule butterflyfish, halfmoon butterflyfish, moon butterflyfish, raccoon butterfly, raccoon, raccoon coralfish, and redstriped butterflyfish, is a species of marine ray-finned fish, a butterflyfish belonging to the family Chaetodontidae. It is found in the Indian and Pacific Oceans. Taxonomy ''Chaetodon lunula'' was first formally described as ''Pomacentrus lunula'' in 1802 by the french naturalist Bernard Germain de Lacépède (1756-1825) with the type locality given as "the Indian Ocean". It belongs to the large subgenus ''Rabdophorus'' which might warrant recognition as a distinct genus. In this group, its closest relative is probably the very similar Red Sea raccoon butterflyfish or diagonal butterflyfish, ''C. fasciatus''. Other close relatives appear to be the black butterflyfish, '' C. flavirostris''), Philippine butterflyfish, ''C. adiergastos'', and perhaps also t ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...
