(A) Ventilation frequencies ( f v ). (B) Opercula opening amplitudes (OA). (C) Opercula opening times (OT). (D) Opercula opening velocity (OV). Data points and error bars in all plots represent means and SEM of each metric normalized to the initial value for each animal, and averaged for three specimens of each species. For conventions of quantification and presentation of grouped data as a function of temperature, see Materials and Methods.
