teleost
This term is primarily used in ichthyology and evolutionary biology to distinguish the vast majority of modern bony fish from more primitive groups like sturgeons or lungfish. It carries a technical, scientific register and is rarely encountered in casual conversation, where the broader term "bony fish" is preferred.
In a laboratory or academic setting, the word often appears in the context of developmental biology and genetics, particularly when discussing model organisms like the zebrafish. It describes a specific anatomical blueprint, emphasizing the presence of a symmetrical tail and a calcified skeleton.
