CBS' Zoo is adding two new faces for season two.

Vampire Diaries alum Alyssa Diaz and Show Me a Hero star Josh Salatin have joined the summer drama as series regulars, The Hollywood Reporter has learned.

Diaz will play Dariela, who is part of a military unit which encounters a strange and troubling new development in the animal mutation. The actress's other credits include Ray Donovan and Army Wives. Diaz is repped by Joseph Le Talent Agency and Swerissen Management.

Salatin will portray Logan, a mysterious stranger that Jamie (Kristen Connolly) encounters who may be hiding a dangerous secret from her. The actor, whose credits also include The Following and The Carrie Diaries, is repped by UTA and managed by Kyle Luker at Industry Entertainment. 

Zoo, based on James Patterson and Michael Ledwidge's best-selling novel, centers on a group of individuals trying to investigate a mysterious pandemic as animal attacks upon humans become more coordinated and ferocious. James Wolk toplines the thriller, which is executive produced by Jeff Pinker, Josh Appelbaum, Andre Nemec, Scott Rosenberg, Michael Katleman, James Mangold, Cathy Konrad, Bill Robinson, Leopoldo Gout, Steve Bowen and Patterson. Billy Burke, Nonso Anozie and Nora Arnezeder also star.

Zoo is CBS' sole returning summer drama and will be joined by two freshman series, comic-thriller BrainDead and murder-mystery series American Gothic.
