Cephaloscyllium Umbratile By Jordan And Fowler
''Cephaloscyllium'' is a genus of catsharks, and part of the family Scyliorhinidae, commonly known as swellsharks because of their ability to inflate their bodies with water or air as a defense against predators. These sluggish, bottom-dwelling sharks are found widely in the tropical and temperate coastal waters of the Indian and Pacific Oceans. They have stocky, spindle-shaped bodies and short, broad, and flattened heads. The mouth is capacious, containing many small teeth and lacking furrows at the corners. The two dorsal fins are placed far back on the body, with the first much larger than the second. Different species have various color patterns of saddles, blotches, reticulations, and/or spots. The largest members of the genus can grow over in length. Swellsharks prey on a variety of fishes and invertebrates, and are oviparous, with females producing egg capsules in pairs. They are harmless and have been deemed of having no commercial value. Taxonomy The genus ''Cephalos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Australian Swellshark
The Australian swellshark (''Cephaloscyllium laticeps'') or draughtboard shark, is a species of catshark, and part of the family Scyliorhinidae, endemic to southern Australia. This bottom-dwelling species can be found on the continental shelf down to a depth of . Usually measuring long, it is a stout-bodied, broad-headed shark with a short tail and a first dorsal fin much larger than the second. It can be identified by its variegated dorsal coloration of brown or grey patches and numerous spots. Australian swellsharks are sedentary and mainly nocturnal, with most individuals remaining within the same local area throughout the year. It feeds on small crustaceans, cephalopods, and fish. When threatened, it responds by rapidly taking in water or air to inflate its body, hence the name "swellshark". This shark is oviparous and females lay pairs of distinctively ridged egg capsules at 20- to 30-day intervals. The eggs hatch after 11–12 months. Harmless and of little commerci ...

Greek Language
Greek ( el, label=Modern Greek, Ελληνικά, Elliniká, ; grc, Ἑλληνική, Hellēnikḗ) is an independent branch of the Indo-European family of languages, native to Greece, Cyprus, southern Italy (Calabria and Salento), southern Albania, and other regions of the Balkans, the Black Sea coast, Asia Minor, and the Eastern Mediterranean. It has the longest documented history of any Indo-European language, spanning at least 3,400 years of written records. Its writing system is the Greek alphabet, which has been used for approximately 2,800 years; previously, Greek was recorded in writing systems such as Linear B and the Cypriot syllabary. The alphabet arose from the Phoenician script and was in turn the basis of the Latin, Cyrillic, Armenian, Coptic, Gothic, and many other writing systems. The Greek language holds a very important place in the history of the Western world. Beginning with the epics of Homer, ancient Greek literature includes many works of lasting impo ...

Bernard Séret
Bernard (''Bernhard'') is a French and West Germanic masculine given name. It is also a surname. The name is attested from at least the 9th century. West Germanic ''Bernhard'' is composed from the two elements ''bern'' "bear" and ''hard'' "brave, hardy". Its native Old English reflex was ''Beornheard'', which was replaced by the French form ''Bernard'' that was brought to England after the Norman Conquest. The name ''Bernhard'' was notably popular among Old Frisian speakers. Its wider use was popularized due to Saint Bernhard of Clairvaux (canonized in 1174). Bernard is the second most common surname in France. Geographical distribution As of 2014, 42.2% of all known bearers of the surname ''Bernard'' were residents of France (frequency 1:392), 12.5% of the United States (1:7,203), 7.0% of Haiti (1:382), 6.6% of Tanzania (1:1,961), 4.8% of Canada (1:1,896), 3.6% of Nigeria (1:12,221), 2.7% of Burundi (1:894), 1.9% of Belgium (1:1,500), 1.6% of Rwanda (1:1,745), 1.2% of Germany ( ...

William Toby White
William Toby White is an Australian ichthyologist. He studies speciation and biodiversity of shark, ray, and skate species (subclass Elasmobranchii) through morphological and molecular systematics. Education White received bachelor's (1997) and doctoral (2003) degrees in Biological Science from Murdoch University in Perth, Australia. His doctoral thesis, "Aspects of the biology of elasmobranchs in a subtropical embayment in Western Australia and of chondrichthyan fisheries in Indonesia", examined 1) spatial partitioning of food resources available to shark, ray, and skate species in Shark Bay (off the western coast of Australia), and 2) the relative frequencies of shark, ray, and skate species caught in fisheries off the coast of southeastern Indonesia. From 2004 to 2006 he did post-doctoral training, also at Murdoch University. Professional career Since 2006, White has served as ichthyologist at the Australian National Fish Collection which is part of the CSIRO Marine and ...

Whitefin Swellshark
The whitefin swellshark (''Cephaloscyllium albipinnum'') is a little-known species of catshark, belonging to the family Scyliorhinidae, endemic to southeastern Australia. It is found down, on the outer continental shelf and upper continental slope. Reaching in length, this shark has a very thick body and a short, broad, flattened head with a large mouth. It is characterized by a dorsal color pattern of dark saddles and blotches over a brown to gray background, and light fin margins. When threatened the whitefin swellshark can inflate itself with water or air to increase its size. Reproduction is oviparous. As of 2019 The International Union for Conservation of Nature(IUCN) has assessed this species as Critically Endangered due to the significant decline of the population. Taxonomy Early specimens of the whitefin swellshark were often mistaken for the Australian swellshark (''C. laticeps'') or the draughtsboard shark (''C. isabellum''). In 1994, it was identified as a new sp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Type Specimen
In biology, a type is a particular wiktionary:en:specimen, specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally attached. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set (mathematics), set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the International Code of Nomenclature for algae, fungi, and plants (ICN), the ...

Blotchy Swellshark
The blotchy swellshark, or Japanese swellshark, (''Cephaloscyllium umbratile'') is a common species of catshark, belonging to the family Scyliorhinidae. The Blotchy swellshark is found at depths of in the northwestern Pacific Ocean, from Japan to Taiwan. It is benthic in nature and favors rocky reefs. Reaching in length, this thick-bodied shark has a broad head, large mouth, and two unequally-sized dorsal fins positioned far back past the pelvic fins. It can be identified by its dorsal coloration, consisting of seven brown "saddles" and extensive darker mottling on a light tan background. This species has often been confounded with the draughtsboard shark (''C. isabellum'') and the Sarawak pygmy swellshark (''C. sarawakensis'') in scientific literature. Voracious and opportunistic in feeding habits, the blotchy swellshark is known to consume numerous types of fishes and invertebrates, including an unusually high diversity of cartilaginous fishes.

Swellshark
The swell shark (''Cephaloscyllium ventriosum'') is a catshark in the family Scyliorhinidae. It is found in the tropical and subtropical eastern Pacific Ocean from between central California to southern Mexico, with an additional population off the coast of Chile. As a defense, the swell shark is able to expand to approximately double its regular size by swallowing water. Taxonomy When discovered in 1880, the swell shark was first described as ''Scyllium ventriosum'', but was later changed to ''Cephaloscyllium ventriosum''. The genus name comes from the Greek word ''kephale'', which means "head", and ''skylla'', which means a certain kind of shark. The species name comes from the Latin word ''ventrĭōsus'', which means "large-bellied". The species name refers to its ability to enlarge itself by taking in water. Distribution and habitat The swell shark is found in the eastern Pacific Ocean, from the central California coast to southern Mexico. There is an additional population ...

Draughtsboard Shark
The draughtsboard shark (''Cephaloscyllium isabellum'') is a species of catshark, and part of the family (biology), family Catshark, Scyliorhinidae, so named for its "checkerboard" color pattern of dark blotches. It is Endemism, endemic to New Zealand, where it is also known as the carpet shark (which usually refers to the entire order (biology), order Orectolobiformes). This shark typically reaches in length and has a thick body with a broad, flattened head and a capacious mouth. Its two dorsal fins are placed far back on the body, with the first much larger than the second. Occurring down to a depth of , the draughtsboard shark frequents rocky reefs during the day and sandy flats at night. Its diet consists of fishes and invertebrates. When threatened by a predator, it can take water or air into its body to inflate its body, which may be the cause of its unusual habit of bark (utterance), barking like a dog. This species is oviparous, with females laying smooth, tendril-bear ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
