Yellowfin Goatfish
The yellowfin goatfish (''Mulloidichthys vanicolensis'') is a species of goatfish native to the Indian Ocean and the Pacific Ocean. Description ''M. vanicolensis'' can reach a maximum length of . The back is red-orange, while the flanks and the belly are whitish and the fins are yellow. The sides show a yellow longitudinal band. This species feeds on crustaceans or worms at night. By day, it forms large aggregations. Distribution and habitat These fish are widespread in the Indo-Pacific, from the Red Sea to Hawaii and the Tuamotus, north to Japan and to Lord Howe Island to the south. The yellowfin goatfish is a reef-associated species. It usually can be found in lagoons and seaward reefs at depths of .

Hurghada
Hurghada (; ar, الغردقة ', ) is a city in the Red Sea Governorate of Egypt. It is one of the country's main tourist centres located on the Red Sea coast. Overview Hurghada was founded in the early 20th century. For many decades it was a small fishing village, but it has grown into a major Red Sea resort as a result of Egyptian and foreign investment that began in the 1980s. Holiday resorts and hotels provide facilities for windsurfing, kitesurfing, yachting, scuba diving and snorkeling. The city is known for its watersports, nightlife and warm weather. Daytime temperatures are around most of the year, and during July and August temperatures can reach over . Hurghada is a popular holiday destination for Europeans, especially during the winter, and some spend Christmas and New Year there. Tourist numbers from Russia dropped significantly after the Metrojet Flight 9268 plane crash in November 2015. Hurghada extends for about along the coast, but does not reach far into ...

Lord Howe Island
Lord Howe Island (; formerly Lord Howe's Island) is an irregularly crescent-shaped volcanic remnant in the Tasman Sea between Australia and New Zealand, part of the Australian state of New South Wales. It lies directly east of mainland Port Macquarie, northeast of Sydney, and about southwest of Norfolk Island. It is about long and between wide with an area of , though just of that comprise the low-lying developed part of the island. Along the west coast is a sandy semi-enclosed sheltered coral reef lagoon. Most of the population lives in the north, while the south is dominated by forested hills rising to the highest point on the island, Mount Gower (). The Lord Howe Island Group comprises 28 islands, islets, and rocks. Apart from Lord Howe Island itself, the most notable of these is the volcanic and uninhabited Ball's Pyramid about to the southeast of Howe. To the north lies a cluster of seven small uninhabited islands called the Admiralty Group. The first repo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fish Of The Pacific Ocean
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. Most fis ...

Mullidae
The goatfishes are perciform fish of the family Mullidae. The family is also sometimes referred to as the red mullets, which also refers more narrowly to the genus ''Mullus''. The family name and the English common name mullet derived from Latin ''mullus'', the red mullet; other than the red mullet and the striped red mullet or surmullet, the English word "mullet" generally refers to a different family of fish, the Mugilidae or gray mullets.''Oxford English Dictionary''''s.v.'' 'mullet'/ref> Description Goatfish are characterized by two chin barbels (or goatee), which contain chemosensory organs and are used to probe the sand or holes in the reef for food. Their bodies are deep and elongated, with forked tails and widely separated dorsal fins. The first dorsal fin has 6-8 spines; the second dorsal has one spine and 8-9 soft rays, shorter than anal fin. Spines in anal fin 1 or 2, with 5-8 soft rays. They have 24 vertebrae. Many goatfish are brightly colored. The largest specie ...

Digenea
Digenea (Gr. ''Dis'' – double, ''Genos'' – race) is a class of trematodes in the Platyhelminthes phylum, consisting of parasitic flatworms (known as ''flukes'') with a syncytial tegument and, usually, two suckers, one ventral and one oral. Adults commonly live within the digestive tract, but occur throughout the organ systems of all classes of vertebrates. Once thought to be related to the Monogenea, it is now recognised that they are closest to the Aspidogastrea and that the Monogenea are more closely allied with the Cestoda. Around 6,000 species have been described to date. Morphology Key features Characteristic features of the Digenea include a syncytial tegument; that is, a tegument where the junctions between cells are broken down and a single continuous cytoplasm surrounds the entire animal. A similar tegument is found in other members of the Neodermata; a group of platyhelminths comprising the Digenea, Aspidogastrea, Monogenea and Cestoda. Digeneans possess a vermifo ...

Apocreadiidae
Apocreadiidae is a family of parasitic worms in the class Trematoda Trematoda is a class of flatworms known as flukes. They are obligate internal parasites with a complex life cycle requiring at least two hosts. The intermediate host, in which asexual reproduction occurs, is usually a snail. The definitive h .... Characteristics Members of the family are characterised by having extensive vitelline (yolk producing) follicles, eye-spot pigment dispersed in the front half of the body, a rod-shaped excretory vesicle, no cirrus-sac and the genital pore just in front of the ventral sucker or occasionally just behind it. Genera The World Register of Marine Species lists the following genera: *Apocreadiinae Skrjabin, 1942 **'' Callohelmis'' Cribb & Bray, 1999 **'' Choanodera'' Manter, 1940 **'' Crassicutis'' Manter, 1936 **'' Dactylotrema'' Bravo-Hollis & Manter, 1957 **'' Homalometron'' Stafford, 1904 **'' Marsupioacetabulum'' Yamaguti, 1952 **'' Microcreadium'' Simer, 1929 **' ...

Pennulituba
''Pennulituba'' is a genus of monogeneans belonging to the family Ancyrocephalidae (sometimes considered as belonging to the Dactylogyridae). Etymology The generic name is derived from the Latin ("winglet") and ("tube"), referring to the male copulatory organ being characterized by a wing-shaped membrane. Host and Species The two known species of the genus are parasitic on the gills of the yellowfin goatfish ''Mulloidichthys vanicolensis'' (Mullidae) and were collected in the waters of the Pacific Ocean The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south, and is bounded by the contin ... off New Caledonia.

Monogenea
Monogeneans are a group of ectoparasitic flatworms commonly found on the skin, gills, or fins of fish. They have a direct lifecycle and do not require an intermediate host. Adults are hermaphrodites, meaning they have both male and female reproductive structures.L.A. Tubbsa et al. (2005). "Effects of temperature on fecundity in vitro, egg hatching and reproductive development of ''Benedenia seriolae'' and ''Zeuxapta seriolae'' (Monogenea) parasitic on yellowtail kingfish Seriola lalandi". ''International Journal for Parasitology''(35), 315–327. Some monogeneans are oviparous (egg-laying) and some are viviparous (live-bearing). Oviparous varieties release eggs into the water. Viviparous varieties release larvae, which immediately attach to another host. The genus ''Gyrodactylus'' is an example of a viviparous variety, while the genus ''Dactylogyrus'' is an example of an oviparous variety. Signs and symptoms Freshwater fish that become infected with this parasite become let ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
