They form a sister group to the tunicates, together forming the olfactores. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Tetrapods emerged within lobe-finned fishes, so cladistically they are fish as well. However, traditionally fish are rendered obsolete or paraphyletic by excluding the tetrapods (i.e., the amphibians, reptiles, birds and mammals which all descended from within the same ancestry). Because in this manner the term "fish" is defined negatively as a paraphyletic group, it is not considered a formal taxonomic grouping in systematic biology. The traditional term pisces (also ichthyes) is considered a typological, but not a phylogenetic classification. - Krill are small crustaceans of the order Euphausiacea, and are found in all the world's oceans. The name "krill" comes from the Norwegian word "", meaning "small fry of fish", which is also often attributed to species of fish. - Euphausia is the largest genus of krill, and is placed in the family Euphausiidae. There are 31 species known in this genus, including Antarctic krill ("Euphausia superba") and ice krill ("Euphausia crystallorophias") from the Southern Ocean, and North Pacific krill ("Euphausia pacifica") in the Pacific Ocean. What is the relationship between 'stylocheiron' and 'euphausiidae'?

input: Please answer the following: Information: - The individual pursuit is a track cycling event where two cyclists begin the race from a stationary position on opposite sides of the track. The event is held over for men and for women. The two riders start at the same time and set off to complete the race distance in the fastest time. They will ride on the pursuit line at the bottom of the track in order to find the fastest line. This race makes for a good spectacle as the two riders pursue each other attempting to catch the other rider who started on the other side of the track. If the catch is achieved, then the successful pursuer is declared the winner. However, they can continue to ride the rest of the race distance in order to set the fastest time in a qualifying race or a record in a final. - Track cycling is a bicycle racing sport usually held on specially built banked tracks or velodromes (but many events are held at older velodromes where the track banking is relatively shallow) using track bicycles. - The team pursuit is a track cycling event similar to the individual pursuit , except that two teams , each of up to four riders , compete , start on opposite sides of the velodrome . - A velodrome is an arena for track cycling. Modern velodromes feature steeply banked oval tracks, consisting of two 180-degree circular bends connected by two straights. The straights transition to the circular turn through a moderate easement curve. - A track bicycle or track bike is a bicycle optimized for racing at a velodrome or outdoor track. Unlike road bicycles, the track bike is a fixed-gear bicycle; thus, it has only a single gear ratio and has neither a freewheel nor brakes. Tires are narrow and inflated to high pressure to reduce rolling resistance. Tubular tires are most often used in track racing and training, though advances in clincher tire design have seen them being used somewhat more often. What is the relationship between 'team pursuit' and 'sport'?
