Cardiocephaloides Longicollis
''Cardiocephaloides longicollis'' is a species of flukes. The life cycle of ''C. longicollis'' is asexual as well as complex. Its asexual stage resides in the body of whelks where it replicates many times, and eventually its eggs are dispersed in the water through feces. ''C.longicollis'' begin their early life as free swimming miracidia larvae in the water. They go on to infect snails (intermediate host), and a variety of fishes, usually second intermediate host, in the form of a cercariae. While ''C.longicollis'' has previously been recorded in 19 fish species, researchers have found 12 other species which are viable hosts for ''C.longicollis'' making for a grand total of 31 aquatic species. The final host for this parasite are the gulls that eat the infected fish in which the parasite has formed cysts in. __TOC__ Life cycle The asexual life cycle of ''C. longicollis'' is complex which involves carnivorous scavenging whelks, a variety of fish, and gulls.

Trematode
Trematoda is a Class (biology), class of flatworms known as flukes. They are obligate parasite, obligate internal Parasitism, parasites with a complex biological life cycle, life cycle requiring at least two Host_(biology), hosts. The intermediate host, in which asexual reproduction occurs, is usually a snail. The definitive host, where the flukes sexually reproduce, is a vertebrate. Infection by trematodes can cause disease in all five traditional vertebrate classes: mammals, birds, amphibians, reptiles, and fish. Etymology Trematodes are commonly referred to as flukes. This term can be traced back to the Old English name for flounder, and refers to the flattened, rhomboidal shape of the organisms. Taxonomy There are 18,000 to 24,000 known species of trematodes, divided into two subclasses — the Aspidogastrea and the Digenea. Aspidogastrea is the smaller subclass, comprising 61 species. These flukes mainly infect Bivalvia, bivalves and Osteichthyes, bony fishes.https://www.bi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boops Boops
''Boops boops'' (; from Ancient Greek , literally 'cow-eye'), commonly called the bogue, is a species of seabream native to the eastern Atlantic. Its common name in most languages refers to its large ("bug") eyes. Distribution and habitat The species is found off the coasts of Europe, Africa, the Azores and the Canary Islands, from Norway to Angola, and in the Mediterranean and Black Seas. It avoids brackish waters such as the Baltic Sea. A demersal and semi-pelagic feeder, it can generally be found at a depth of , and infrequently down to . Ecology It consumes seaweed, crustaceans, and some plankton, in schools that rise to the surface at night. Individuals can reach , but average . Sex determination in the bogue is unclear. It has variously been described as a rudimentary intersex organism, with a few intersex individuals, or a protogynous intersex, with individuals starting out life as females, and some becoming male later on.

Black Goby
The black goby (''Gobius niger'') is a species of ray-finned fish found in the Eastern Atlantic and Mediterranean Sea and Black Sea. It inhabits estuaries, lagoons, and inshore water over seagrass and algae. It feeds on a variety of invertebrates and sometimes small fish. This species can also be found in the aquarium trade. This fish reaches a maximum length of TL. This fish's neck is scaled and both of its dorsal fins have a black spot on the front end. Description The black goby is deeper-bodied than the common goby, sand goby and two-spotted goby with a more rounded snout and generally a larger size. It has two dorsal fins that are almost continuous, the anterior one having six spines, which may project from the fin membrane, and the posterior and shorter one having soft rays. The posterior dorsal fin terminates close to the caudal peduncle in contrast to the common and sand gobies where there is a long gap. The pelvic fins are fused.

Giant Goby
The giant goby (''Gobius cobitis'') is a species of goby native to coastal marine and brackish waters of the eastern Atlantic, the Mediterranean Sea and the Black Sea at depths of from . This species is of minor importance to commercial fisheries and is also popular as a game fish. Description The giant goby, which grows to in length, is greyish to olive brown with 'pepper and salt' markings. These are especially notable in smaller specimens. In the breeding season the male is darker than the female. The body is covered in small scales, and the tail stalk is short. The eyes are small. Habitat The giant goby inhabits rock pools high up in the intertidal zone of sheltered shores. Occupied pools typically contain boulders under which the giant goby can take shelter, and have inputs of freshwater, so the water in the pools is usually brackish. Diet This species has been recorded to feed upon polychaete worms, green algae of the genus ''Ulva'', amphipods, crabs and insec ...

Bucchich's Goby
Bucchich's goby (''Gobius bucchichi'') is a species of goby native to the Eastern Mediterranean Sea (at least the Adriatic and Aegean Seas) and perhaps the Black Sea. It has traditionally been considered to be more widespread, but in 2016 the similar incognito goby (''G. incognitus'') was described. It had been confused with the Bucchich's goby and much information formerly published for this species is now considered to actually be for the incognito goby. The Bucchich's goby prefers coastal waters with a sandy or muddy substrate with seagrass patches or tide pools at depths of from . Its diet consists of polychaete worms, amphipods, molluscs and algae. This species can reach a total length Fish measurement is the measuring of individual fish and various parts of their anatomies.

Three-spined Stickleback
The three-spined stickleback (''Gasterosteus aculeatus'') is a fish native to most inland and coastal waters north of 30°N. It has long been a subject of scientific study for many reasons. It shows great morphological variation throughout its range, ideal for questions about evolution and population genetics. Many populations are anadromous (they live in seawater but breed in fresh or brackish water) and very tolerant of changes in salinity, a subject of interest to physiologists. It displays elaborate breeding behavior (defending a territory, building a nest, taking care of the eggs and fry) and it can be social (living in shoals outside the breeding season) making it a popular subject of inquiry in fish ethology and behavioral ecology. Its antipredator adaptations, host-parasite interactions, sensory physiology, reproductive physiology, and endocrinology have also been much studied. Facilitating these studies is the fact that the three-spined stickleback is easy to find in na ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shore Rockling
The shore rockling (''Gaidropsarus mediterraneus'') is a mottled brown, small, elongated fish. This eel-like fish has three barbels on its head, with the second dorsal fin and the anal fin running the length of most of its body. These fins may be viewed moving in a continuous wave motion. The shore rockling is often confused with the five-bearded rockling (''Ciliata mustela'') and the larger three-bearded rockling (''Gaidropsarus vulgaris''), due to their similar colourings, shape, and habitat. As the name suggests, the main visual differences are the five-bearded rockling having five barbels around its mouth, whereas the three-bearded rockling has a significant redness to its brown colouring when compared to the shore rockling. Shore rocklings can also be eaten, as the flesh is also very tender. Shore rocklings live in rocks, feeding on both worms and crustaceans. They are distributed in the eastern Atlantic from the mid-Norwegian coast south to the Straits of Gibraltar and in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
