"It appears that one of the seals, RK60, may have been observed 'logging' (floating listlessly) in Kaneohe Bay in the days leading up to the discovery of her body. This logging behavior can be a symptom of a sick seal," NOAA said. "Reports of this behavior did not reach NOAA until after RK60 died, but more timely reporting may have given NOAA a chance to intervene and help her."
