The brown tree snake in Guam is the exotic species that was not introduced intentionally among the options given. The snake was accidentally transported via aircraft from the Solomon Islands to Guam.

Step-by-step explanation:

Among the given options, the brown tree snake in Guam was not introduced intentionally. This is an example of an exotic species, which are species that have been introduced, either intentionally or unintentionally, into an ecosystem where they did not evolve. In this case, the brown tree snake, or Boiga irregularis, was accidentally introduced via aircraft from the Solomon Islands to Guam in 1950.
