التعريف: overall repetitive or reflective pattern in the body of one individual of this taxon. eg: bilateral symmetry, rotational symmetry, radial symmetry
التعريف: Body/caudal fin propulsion, retaining eel-like body movements and exploiting interactions between the sidewash from an anterior median fin with the next posterior fin, increasing its effective angle of attack
التعريف: The institution that holds a type specimen for a given species. The recommended best practice is to use the identifier in a collections registry such as the Biodiversity Collections Index (http://www.biodiversitycollectionsindex.org/).
