“…Due to the absence of an erupted tooth and lack of adult colour patterning, these individuals were likely females or juveniles. The distribution of Gray’s and strap-toothed beaked whales supports this identification, with both species previously documented off Western Australia, and Gray’s beaked whale being the most commonly recorded species of beaked whales in Western Australian waters [41]. Photographs from Observation 4 in 2016 show distinct diagnostic features and allow for a positive identification of a strap-toothed whale (Fig 7A).…”

“…What is known about beaked whale habitat preference indicates that they forage in deep water near the continental slope, in subsea canyons, or along steep-sided islands, and are often associated with cold-core eddy intrusions, which promote upwelling of nutrient-rich water [34–40]. In Australian waters, knowledge of their biology and distribution has been a result of intermittent sightings and stranding records [41–43]. …”

“…The Western Australian coast has the highest species diversity (10) of beaked whale strandings compared to other Australian coasts, with a total of 74 Ziphiidae strandings from 1940 to 2010 [41]. Gray’s beaked whale ( Mesoplodon grayi ) was the most frequently reported stranded species (44%), and has been involved in the largest mass stranding (seven individuals) of all beaked whales stranded in Western Australia [41].…”

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.

“…For M. layardii , Shirihai and Jarrett (), Groom et al . (), and MacLeod () all reported group sizes of up to 5, while Best () cited 2–6 individuals from at‐sea sightings in the South African subregion. Our sighting of an estimated 10 individuals off Bremer Bay appears to be the largest group of strap‐toothed beaked whales reported to date, and may be near the maximum for all mesoplodonts.…”
