MIAMI (AP) — The U.S. Fish and Wildlife Service is seeking more public comment on a proposal to add five types of giant snakes to an existing federal python ban.

Officials have proposed adding boa constrictors, reticulated pythons and three species of anacondas to the ban that already prohibits anyone from importing Burmese pythons, yellow anacondas and northern and southern African pythons into the U.S. or transporting them across state lines.
