A zoological expedition was a mission with the aim of preserving and studying animals.

In 2267, after Spock expressed his misgivings about killing the Horta, as it might be the lone survivor of an otherwise extinct species, James T. Kirk reminded him that their mission was to protect the Janus VI colony and get the pergium production back in operation, rather than a zoological expedition. (TOS: "The Devil in the Dark")
