In summary, these findings suggest that crabeater seals
are able to maintain or increase body mass and condition
while foraging in winter despite reduced light levels, and
shifts in the depth distribution and abundance of their
primary prey species, Antarctic krill. In addition, the
morphometric method proved to be a useful technique in
accessing condition in crabeater seals and will be a valuable
tool to access how crabeater seals and their prey are
responding to changes in the environment.
