  • Title: The visual pigments of the weever fish, Trachinus vipera: a microspectrophotometric study.
    Author: Bowmaker JK, Kunz YW.
    Journal: Exp Biol; 1985; 44(2):139-45. PubMed ID: 3850027.
    Abstract:
    Microspectrophotometric analyses of the visual pigments of the weever fish, Trachinus vipera, demonstrate the presence of a rhodopsin with peak sensitivity at 502 nm, and two cone visual pigments. Identical twin cones are green-sensitive containing a P5281, and single cones are blue-sensitive containing a P4401. The dichromacy of the weever is discussed in relation to its photic environment and feeding behaviour.
