Sphyraena Putnamae
''Sphyraena putnamae'', the sawtooth, chevron or military barracuda, is a species of barracuda found in all tropical seas and temperate waters of major oceans with the exception of the eastern pacific. It is found near shores in bays, turbid lagoons, and some reefs. A recognizable feature is the many (about 15) dark chevron-shaped markings along its side, and its forked caudal fin. It spends its time in the shallow part of the sea off the coast, and stays closers to the surface levels of the open ocean. It can reach an age of 14 years old, and grow up to six feet long and over 100 pounds. Modern classification There is not currently any supported phylogenetic hypothesis including all twenty-nine species in '' Sphyraena''. However, there is phylogenetic data and a well-supported phylogeny that includes twenty of these species, including ''Sphyraena putnamae''. By analyzing three of the most frequently found nuclear and mitochondrial genes in ''Sphyraena'', as well as using Bayesian ...

Barracuda
A barracuda, or cuda for short, is a large, predatory, ray-finned fish known for its fearsome appearance and ferocious behaviour. The barracuda is a saltwater fish of the genus ''Sphyraena'', the only genus in the family Sphyraenidae, which was named by Constantine Samuel Rafinesque in 1815. It is found in tropical and subtropical oceans worldwide ranging from the eastern border of the Atlantic Ocean to the Red Sea, on its western border the Caribbean Sea, and in tropical areas of the Pacific Ocean. Barracudas reside near the top of the water and near coral reefs and sea grasses. Barracudas are targeted by sport-fishing enthusiasts. Etymology The common name "barracuda" is derived from Spanish, with the original word being of possibly Cariban origin. Description Barracuda are snake-like in appearance, with prominent, sharp-edged, fang-like teeth, much like piranha, all of different sizes, set in sockets of their large jaws. They have large, pointed heads with an unde ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Megalaspis Cordyla
The torpedo scad (''Megalaspis cordyla''), also known as the hardtail scad, finny scad, finletted mackerel scad or cordyla scad, is a species of moderately large marine fish classified in the jack and horse mackerel family, Carangidae. The torpedo scad is distributed throughout the tropical Indo-Pacific region, ranging from South Africa in the west to Tonga in the east, extending to Japan in the north and Australia in south. It is a schooling pelagic fish which occupies the surface layers of both inshore and offshore oceanic waters. The torpedo scad is easily identified by both its 'torpedo' shaped body and a series of detached finlets at the rear of both the dorsal and anal fins. The largest recorded individual was 80 cm long and weighed 4 kg, although it is more common at lengths less than 40 cm. It is a predatory species, taking a variety of fish, cephalopods and crustaceans by both active and filter feeding. There is a shift in diet as the species grow; ...

Predators
Predation is a biological interaction where one organism, the predator, kills and eats another organism, its prey. It is one of a family of common feeding behaviours that includes parasitism and micropredation (which usually do not kill the host) and parasitoidism (which always does, eventually). It is distinct from scavenging on dead prey, though many predators also scavenge; it overlaps with herbivory, as seed predators and destructive frugivores are predators. Predators may actively search for or pursue prey or wait for it, often concealed. When prey is detected, the predator assesses whether to attack it. This may involve ambush or pursuit predation, sometimes after stalking the prey. If the attack is successful, the predator kills the prey, removes any inedible parts like the shell or spines, and eats it. Predators are adapted and often highly specialized for hunting, with acute senses such as vision, hearing, or smell. Many predatory animals, both vertebrate and ...

Koh Tao
Ko Tao ( th, เกาะเต่า, , ) is an island in Thailand and is part of the Chumphon Archipelago on the western shore of the Gulf of Thailand. It covers an area of about 21 km2 (8 sq mi). Administratively it is a subdistrict (''tambon'') of Ko Pha-ngan District (''amphoe'') of Surat Thani Province. , its official population was 1,382. The main settlement is Ban Mae Haad. The economy of the island is almost exclusively centered on tourism, especially scuba diving. Scuba diving is extremely popular in Ko Tao due to clear visibility, inexpensive pricing and the range of sealife to be seen. History Before being settled the island would be occasionally visited by fishermen from neighbouring islands looking for shelter in a storm or just resting before continuing on their journeys. It would appear from old maps and descriptions that this island was known by European cartographers and mariners as "Pulo Bardia", indicating that it was first settled by Malayo-Polynes ...

Bucephalidae
Bucephalidae is a family of trematodes that parasitize fish. They lack suckers, having instead a muscular organ called a "rhynchus" at the front end which they use to attach to their hosts. The characteristics of the rhynchus are used to help define the genera of the family.Hassanine, R. M. E. (2002)On three digenean trematodes (Family Bucephalidae) from marine teleost fishes with new record from the Red Sea.''Egyptian Journal of Aquatic Biology and Fisheries'', 6(3), 1–16.

Kudoa
''Kudoa'' is a genus of Myxozoa and the only genus recognized within the monotypic family Kudoidae. There are approximately 100 species of ''Kudoa'' all of which Parasitism, parasitize on Marine life, marine and Estuary, estuarine fish. ''Kudoa'' are most commonly known and studied for the negative effects the genus has on commercial fishing and aquaculture industries. Description The genus ''Kudoa'' is identified by the possession of four or more shell valves composed of a fragile membrane and arranged in a wikt:quadrate, quadrate or Star-shaped, stellate pattern. The maximum number of shell valves in any described ''Kudoa'' species is 13. Each of these valves has a polar capsule. The genus ''Kudoa'' was originally part of the genus ''Chloromyxum'' because of the distribution of their polar capsules, however, it was later determined to be a separate genus. Each ''Kudoa'' has two sporoplasm cells, one enclosed by the other. Most ''Kudoa'' are histozoic parasites, with a few spe ...

Myxozoa
Myxozoa (etymology: Greek: μύξα ''myxa'' "slime" or "mucus" + thematic vowel o + ζῷον ''zoon'' "animal") is a subphylum of aquatic cnidarian animals – all obligate parasites. It contains the smallest animals ever known to have lived. Over 2,180 species have been described and some estimates have suggested at least 30,000 undiscovered species. Many have a two-host lifecycle, involving a fish and an annelid worm or a bryozoan. The average size of a myxosporean spore usually ranges from 10 μm to 20 μm, whereas that of a malacosporean (a subclade of the Myxozoa) spore can be up to 2 mm. Myxozoans can live in both freshwater and marine habitats. Myxozoans are highly derived cnidarians that have undergone dramatic evolution from a free swimming, self-sufficient jellyfish-like creature into their current form of obligate parasites composed of very few cells – sometimes only a single cell. As myxozoans evolved into microscopic parasites, they lost many g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
