(A) Absorbance spectra of visual pigment extracted from the retina of Bathysaurus ferox measured in unbleached and bleached states at pressures of 0.1, 9.0, 20.0, 31.0 and 45.8 MPa. For clarity of presentation all scans have been zeroed at 700 nm. (B) Difference spectra for each pressure constructed using the curves shown in Fig. 1A. Scans have been zeroed at the minimum long-wave absorbance (see Hart et al., 2000).

(A) Relationship between max and pressure for the visual pigment of the animal (Bathysaurus ferox) whose visual pigment difference spectra are shown in Fig. 1B. The data are fitted by the following linear regression: max=0.021943P+484.6437; where P is the pressure in MPa. (B) Relationship between absorbance at the max and pressure for the visual pigment of the animal (Bathysaurus ferox) whose visual pigment difference spectra are shown in Fig. 1B. The data are fitted by the following linear regression: A=5.806x10-5P+0.149787, where A is the absorbance at the max and P is the pressure in MPa.
