Canada, Mexico, U.S. to protect endangered porpoise

MEXICO CITY -- Officials from Mexico, the United States and Canada are teaming up in a plan presented Tuesday to protect the vaquita marina, a highly endangered species of porpoise in the upper Gulf of California.

Canadian and U.S. experts will join their Mexican counterparts in studying the rare animal and working to convince fishermen in Gulf communities to abandon fine-mesh gill nets and other techniques that threaten the species.
