Dear Colleagues, We are pleased to announce the following publication in PLOS ONE: Wellard R, Lightbody K, Fouda L, Blewitt M, Riggs D & Erbe C. (2016)* Killer Whale (Orcinus orca) Predation on Beaked Whales (Mesoplodon spp.) in the Bremer Sub-Basin, Western Australia.* PLOS ONE 11(12): e0166670. doi: 10.1371/journal.pone.0166670 *Abstract*: Observations of killer whales (*Orcinus orca*) feeding on the remains of beaked whales have been previously documented; however, to date, there has been no published account of killer whales actively preying upon beaked whales. This article describes the first field observations of killer whales interacting with, hunting and preying upon beaked whales ( *Mesoplodon* spp.) on four separate occasions during 2014, 2015 and 2016 in the Bremer Sub-Basin, off the south coast of Western Australia.
