Summary
Retinal adaptations to a tide pool environment in ten species of fishes belonging to as many families were studied. These fishes may be grouped into typical or temporary tide pool inhabitants. The retinal structure of these forms may be grouped into three categories viz. 1. visually dependent (good acuity and sensitivity), 2. specialised for dim environments (high sensitivity at the cost of acuity), and 3. poor visual ability.
Zusammenfassung
In zehn Arten aus ebenso vielen Familien werden Anpassungser-scheinungen der Retinastruktur an ein „tide pool”-Milieu untersucht. Die einzelnen Fische lassen sich einteilen in typische und zeitweilige „tide pool” Bewohner. Nach dem Bau der Netzhaut kann man drei verschiedene Gruppen unterscheiden: 1. über-wiegend visuell orientierte Tiere (gute Sehschärfe, hohe Empfindlichkeit); 2. Tiere mit Anpassung an Dämmerungssehen (hohe Empfindlichkeit auf Kosten der Sehschärfe); 3. Arten mit geringer Sehtüchtigkeit.
