Spectral sensitivity of the barnacle, Balanus amphitrite.

W P Stratten, T E Ogden

    The Journal of General Physiology
    |April 1, 1971
    PubMed
    Summary

    Barnacle ocelli spectral sensitivity peaks at 530-540 nm, indicating a single photopigment. Light adaptation broadens spectral sensitivity by altering amplitude-intensity functions.

    Area of Science:

    • Marine biology
    • Sensory physiology
    • Biophysics

    Background:

    • The ocellus in crustaceans like barnacles plays a role in light detection.
    • Understanding spectral sensitivity is crucial for comprehending visual processing in marine invertebrates.

    Purpose of the Study:

    • To determine the spectral sensitivity of the barnacle (Balanus amphitrite) ocellus.
    • To investigate the photopigment characteristics and adaptation mechanisms within the ocellus.

    Main Methods:

    • Measurement of extracellular ocellar potential to assess spectral sensitivity.
    • Utilizing chromatic adapting lights to study receptor responses.
    • Analyzing tapetal fluorescence and corneal transmission to account for optical effects.

    Main Results:

    • Maximum relative spectral sensitivity was observed between 530-540 nm.
    • Evidence suggests the presence of a single photopigment within the ocellar receptors.
    • Spectral sensitivity was broader in the dark-adapted state compared to the light-adapted state.
    • Light adaptation increased the slope of the amplitude-intensity function, influencing spectral bandwidth.

    Conclusions:

    • The barnacle ocellus exhibits peak sensitivity in the green-yellow region of the spectrum.
    • Ocellar light adaptation involves changes in the amplitude-intensity function, affecting spectral bandwidth.
    • Ocellar media have minimal impact on the measured spectral sensitivity.
