Long-spined Sea Scorpion
The long-spined bullhead (''Taurulus bubalis''), also known as the long-spined sea-scorpion, and the long-spined scorpion fish is a coastal fish of the sculpin family Cottidae, inhabiting marine waters of Europe. Description The longspined bullhead is a small fish with a thick, tapering body and a large head and resembles the shorthorn sculpin (''Myoxocephalus scorpius''). It has two spines on each side on the gill cover, the front one extending further than the rear one. The skin is not clad in scales. There is a row of bony tubercles running along the flank on the lateral line and there are backward sloping bony tubercles on the crown of the head. It has a variety of colours ranging from shades of brown or olive green, with cream blotches and four dark, vertical bands. The belly is pale bluish-green but becomes suffused with red in males in the breeding season. Behavior Bullhead are predators that will eat prawns, molluscs and small fish such as gobies and blennies. Despite th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Valerii Ivanovich Gratzianov
The gens Valeria was a patrician (ancient Rome), patrician family at ancient Rome, prominent from the very beginning of the Roman Republic, Republic to the latest period of the Roman Empire, Empire. Publius Valerius Poplicola was one of the Roman consul, consuls in 509 BC, the year that saw the overthrow of the King of Rome, Tarquins, and the members of his family were among the most celebrated statesmen and generals at the beginning of the Republic. Over the next ten centuries, few gens, gentes produced as many distinguished men, and at every period the name of ''Valerius'' was constantly to be found in the lists of annual Roman magistrate, magistrates, and held in the highest honour. Several of the Roman emperor, emperors claimed descent from the Valerii, whose name they bore as part of their official nomenclature.''Dictionary of Greek and Roman Biography and Mythology'', vol.

Bengt Anders Euphrasén
Bengt Anders Euphrasén (born 1756 in the parish of Habo, historical province of Västergötland, Sweden; died 25 December 1796 in Stockholm) was a Swedish botanist. Euphrasén studied at the veterinary school in Skara and then entered Uppsala University where he graduated in 1784. In 1788, with the support of the Royal Swedish Academy of Sciences, Euphrasén made a natural history trip to the Antilles, which included Saint Barthélemy and Saint Christopher island (today Saint Kitts).

Coastal Fish
Coastal fish, also called inshore fish or neritic fish, inhabit the sea between the shoreline and the edge of the continental shelf. Since the continental shelf is usually less than deep, it follows that pelagic coastal fish are generally epipelagic fish, inhabiting the sunlit epipelagic zone.Moyle and Cech, 2004, page 585 Coastal fish can be contrasted with ''oceanic fish'' or ''offshore fish'', which inhabit the deep seas beyond the continental shelves. Coastal fish are the most abundant in the world. They can be found in tidal pools, fjords and estuaries, near sandy shores and rocky coastlines, around coral reefs and on or above the continental shelf. Coastal fish include forage fish and the predator fish that feed on them. Forage fish thrive in inshore waters where high productivity results from upwelling and shoreline run off of nutrients. Some are partial residents that spawn in streams, estuaries and bays, but most complete their life cycles in the zone.Moyle and Cech, ...

Cottidae
The Cottidae are a family of fish in the superfamily Cottoidea, the sculpins. It is the largest sculpin family, with about 275 species in 70 genera.Kane, E. A. and T. E. Higham. (2012)Life in the flow lane: differences in pectoral fin morphology suggest transitions in station-holding demand across species of marine sculpin.''Zoology'' (Jena) 115(4), 223-32. They are referred to simply as cottids to avoid confusion with sculpins of other families. Cottids are distributed worldwide, especially in boreal and colder temperate climates. The center of diversity is the northern Pacific Ocean. Species occupy many types of aquatic habitats, including marine and fresh waters, and deep and shallow zones. A large number occur in near-shore marine habitat types, such as kelp forests and shallow reefs. They can be found in estuaries and in bodies of fresh water. Most cottids are small fish, under in length. The species ''Scorpaenichthys marmoratus'' can be up to in length.Froese, R. and D ...

Predation
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 inv ...

Goby
Goby is a common name for many species of small to medium sized ray-finned fish, normally with large heads and tapered bodies, which are found in marine, brackish and freshwater environments. Traditionally most of the species called gobies have been classified in the order Perciformes as the suborder Gobioidei but in the 5th Edition of ''Fishes of the World'' this suborder is elevated to an order Gobiiformes within the clade Percomorpha. Not all the species in the Gobiiformes are referred to as gobies and the "true gobies" are placed in the family Gobiidae, while other species referred to as gobies have been placed in the Oxudercidae. Goby is also used to describe some species which are not classified within the order Gobiiformes, such as the engineer goby or convict blenny ''Pholidichthys leucotaenia''. The word goby derives from the Latin ''gobius'' meaning "gudgeon", and some species of goby, especially the sleeper gobies in the family Eleotridae and some of the dartfishes are ...

Blenny
Blenny (from the Greek and , mucus, slime) is a common name for many types of fish, including several families of percomorph marine, brackish, and some freshwater fish sharing similar morphology and behaviour. Six families are considered "true blennies", grouped under the order Blenniiformes; its members are referred to as blenniiformids. About 151 genera and nearly 900 species have been described within the order. The order was formerly classified as a suborder of the Perciformes but the 5th Edition of ''Fishes of the World'' divided the Perciformes into a number of new orders and the Blenniiformes were placed in the percomorph clade Ovalentaria alongside the such taxa as Cichliformes, Mugiliformes and Gobiesociformes. Families The six "true blenny" families are: * Blenniidae Rafinesque, 1810 - combtooth blennies, including the sabre-toothed blennies * Chaenopsidae Gill, 1865 - pikeblennies, tubeblennies and flagblennies * Clinidae Swainson, 1839 - clinids, inclu ...

Camouflage
Camouflage is the use of any combination of materials, coloration, or illumination for concealment, either by making animals or objects hard to see, or by disguising them as something else. Examples include the leopard's spotted coat, the battledress of a modern soldier, and the leaf-mimic katydid's wings. A third approach, motion dazzle, confuses the observer with a conspicuous pattern, making the object visible but momentarily harder to locate, as well as making general aiming easier. The majority of camouflage methods aim for crypsis, often through a general resemblance to the background, high contrast disruptive coloration, eliminating shadow, and countershading. In the open ocean, where there is no background, the principal methods of camouflage are transparency, silvering, and countershading, while the ability to produce light is among other things used for counter-illumination on the undersides of cephalopods such as squid. Some animals, such as chameleons and o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fish Egg
An egg is an organic vessel grown by an animal to carry a possibly fertilized egg cell (a zygote) and to incubate from it an embryo within the egg until the embryo has become an animal fetus that can survive on its own, at which point the animal hatches. Most arthropods such as insects, vertebrates (excluding live-bearing mammals), and mollusks lay eggs, although some, such as scorpions, do not. Reptile eggs, bird eggs, and monotreme eggs are laid out of water and are surrounded by a protective shell, either flexible or inflexible. Eggs laid on land or in nests are usually kept within a warm and favorable temperature range while the embryo grows. When the embryo is adequately developed it hatches, i.e., breaks out of the egg's shell. Some embryos have a temporary egg tooth they use to crack, pip, or break the eggshell or covering. The largest recorded egg is from a whale shark and was in size. Whale shark eggs typically hatch within the mother. At and up to , the ostric ...

Algae
Algae (; singular alga ) is an informal term for a large and diverse group of photosynthetic eukaryotic organisms. It is a polyphyletic grouping that includes species from multiple distinct clades. Included organisms range from unicellular microalgae, such as ''Chlorella,'' ''Prototheca'' and the diatoms, to multicellular forms, such as the giant kelp, a large brown alga which may grow up to in length. Most are aquatic and autotrophic (they generate food internally) and lack many of the distinct cell and tissue types, such as stomata, xylem and phloem that are found in land plants. The largest and most complex marine algae are called seaweeds, while the most complex freshwater forms are the ''Charophyta'', a division of green algae which includes, for example, ''Spirogyra'' and stoneworts. No definition of algae is generally accepted. One definition is that algae "have chlorophyll ''a'' as their primary photosynthetic pigment and lack a sterile covering of cells around thei ...
