Fluorescence in situ hybridization ( FISH) is a molecular cytogenetic technique that uses fluorescent probes that bind to only particular parts of a nucleic acid sequence with a high degree of sequence complementarity.
They have been created from several different species of fish: zebrafish were the first GloFish available in pet stores, and recently the black tetra, tiger barb, rainbow shark, Siamese fighting fish, X-ray tetra, and most recently Bronze corydoras have been added to the lineup. They are sold in many colors, trademarked as "Starfire Red ...
A fish (pl.: fish or fishes) 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 ...
A robot fish is a type of bionic robot that has the shape and locomotion of a living fish. Most robot fish are designed to emulate living fish which use body-caudal fin (BCF) propulsion, and can be divided into three categories: single joint (SJ), multi-joint (MJ) and smart material -based "soft-body" design.

The sturddlefish is a hybrid of the American paddlefish ( Polyodon spathula) and the Russian sturgeon ( Acipenser gueldenstaedtii ), accidentally created by researchers in 2019 and announced in 2020. [2] Obtaining living hybrids through breeding individuals from different families is unusual, especially given that the two species' last common ...
Fish can learn how to perform a behavior simply by watching other individuals in action. This is variously called observational learning, cultural transmission, or social learning. For example, fish can learn a particular route after following an experienced leader a few times.
Typically, the eels are chopped (shucked) into rounds and boiled in water and vinegar to make a fish stock with nutmeg and lemon juice, before being allowed to cool. The eel is a naturally gelatinous fish, with the cooking process releasing proteins, like collagen, into the liquid, which solidify upon cooling to form a jelly, though gelatin may ...
Bubble nests, also called foam nests, are created by some fish and frog species as floating masses of bubbles blown with an oral secretion, saliva bubbles, and occasionally aquatic plants. Fish that build and guard bubble nests are known as aphrophils.
