Actinopterygii, members of which are known as ray-finned fish or actinopterygians, is a class of bony fish that comprise over 50% of living vertebrate species. They are so called because of their lightly built fins made of webbings of skin supported by radially extended thin bony spines called lepidotrichia, as opposed to the bulkier, fleshy lobed fins of the sister class Sarcopterygii. Resembling folding fans, the actinopterygian fins can easily change shape and wetted area, providing superior thrust-to-weight ratios per movement compared to sarcopterygian and chondrichthyian fins. The fin rays attach directly to the proximal or basal skeletal elements, the radials, which represent the articulation between these fins and the internal skeleton.
Osteichthyes, also known as osteichthyans or commonly referred to as the bony fish, is a diverse superclass of vertebrate animals that have endoskeletons primarily composed of bone tissue. They can be contrasted with the Chondrichthyes and the extinct placoderms and acanthodians, which have endoskeletons primarily composed of cartilage. The vast majority of extant fish are members of Osteichthyes, being an extremely diverse and abundant group consisting of 45 orders, over 435 families and 28,000 species. It is the largest class of vertebrates in existence today, encompassing most aquatic vertebrates, as well as all semi-aquatic and terrestrial vertebrates.
Sushi is a Japanese dish of prepared vinegared rice, usually with some sugar and salt, plus a variety of ingredients, such as vegetables, meat, or most commonly, seafood, which may be raw or cooked. There are many styles of sushi, and its presentation varies widely, but the one key ingredient is "sushi rice", also referred to as shari (しゃり), or sumeshi (酢飯).
Fishing is the activity of trying to catch fish. Fish are often caught as wildlife from the natural environment, but may also be caught from stocked bodies of water such as ponds, canals, park wetlands and reservoirs. Fishing techniques include hand-gathering, spearing, netting, angling, shooting and trapping, as well as more destructive and often illegal techniques such as electrocution, blasting and poisoning.
Fish and chips is a hot dish consisting of fried fish in batter, served with chips. The dish originated in England, where these two components had been introduced from separate immigrant cultures; it is not known who combined them. Often considered Britain's national dish, fish and chips is a common takeaway food in numerous other countries, particularly English-speaking and Commonwealth nations.
Fish sauce is a liquid condiment made from fish or krill that have been coated in salt and fermented for up to two years. It is used as a staple seasoning in East Asian cuisine and Southeast Asian cuisine, particularly Myanmar, Cambodia, Laos, Philippines, Thailand, and Vietnam. Some garum-related fish sauces have been used in the West since the Roman times.
Catfish are a diverse group of ray-finned fish. Named for their prominent barbels, which resemble a cat's whiskers, catfish range in size and behavior from the three largest species alive, the Mekong giant catfish from Southeast Asia, the wels catfish of Eurasia, and the piraíba of South America, to detritivores, and even to a tiny parasitic species commonly called the candiru, Vandellia cirrhosa. Neither the armour-plated types nor the naked types have scales. Despite their name, not all catfish have prominent barbels or "whiskers". Members of the Siluriformes order are defined by features of the skull and swimbladder. Catfish are of considerable commercial importance; many of the larger species are farmed or fished for food. Many of the smaller species, particularly the genus Corydoras, are important in the aquarium hobby. Many catfish are nocturnal, but others are crepuscular or diurnal.
Hamilton Howard "Albert" Fish was an American serial killer, rapist, child molester and cannibal who committed at least three child murders between July 1924 and June 1928. He was also known as the Gray Man, the Werewolf of Wysteria, the Brooklyn Vampire, the Moon Maniac, and the Boogey Man. Fish was a suspect in at least ten murders during his lifetime, although he only confessed to three murders that police were able to trace to a known homicide. He also confessed to stabbing at least two other people.
Fish farming or pisciculture involves commercial breeding of fish, most often for food, in fish tanks or artificial enclosures such as fish ponds. It is a particular type of aquaculture, which is the controlled cultivation and harvesting of aquatic animals such as fish, crustaceans, molluscs and so on, in natural or pseudo-natural environments. A facility that releases juvenile fish into the wild for recreational fishing or to supplement a species' natural numbers is generally referred to as a fish hatchery. Worldwide, the most important fish species produced in fish farming are carp, catfish, salmon and tilapia.
Pisces (♓︎) is the twelfth and final astrological sign in the zodiac. It is a mutable sign. It spans 330° to 360° of celestial longitude. Under the tropical zodiac, the sun transits this area between about February 19 and March 20. In classical interpretations, the symbol of the fish is derived from the ichthyocentaurs, who aided Aphrodite when she was born from the sea.
A fish is an aquatic, anamniotic, gill-bearing vertebrate animal with swimming fins and a hard skull, but lacking limbs with digits. Fish can be grouped into the more basal jawless fish and the more common jawed fish, the latter including all living cartilaginous and bony fish, as well as the extinct placoderms and acanthodians. Most fish are cold-blooded, their body temperature varying with the surrounding water, though some large active swimmers like white shark and tuna can hold a higher core temperature. Many fish can communicate acoustically with each other, such as during courtship displays.
Pescetarianism is a dietary practice in which seafood is the only source of meat in an otherwise vegetarian diet. The inclusion of other animal products, such as eggs and dairy, is optional. According to research conducted from 2017 to 2018, approximately 3% of adults worldwide are pescetarian.
