▪ Abstract The acuity of compound eyes is determined by interommatidial angles, optical
quality, and rhabdom dimensions. It is also affected by light levels and speed of movement …

Animal Eyes provides a comparative account of all known types of eye in the animal
kingdom, outlining their structure and function with an emphasis on the nature of the optical …

Odonata (dragonflies and damselflies) present an unparalleled insect model to integrate
evolutionary genomics with ecology for the study of insect evolution. Key features of …

Spiders are wonderful creatures. Their varied and complex range of behavior and highly
developed sensory systems are excellently adapted to the environmental conditions-as is …

Sensorimotor control in vertebrates relies on internal models. When extending an arm to
reach for an object, the brain uses predictive models of both limb dynamics and target …

Dragonflies are colorful and large-eyed animals strongly dependent on color vision. Here
we report an extraordinary large number of opsin genes in dragonflies and their …

Aquatic insects are the dominant invertebrate fauna in most freshwater ecosystems, and
figure prominently in the work of a diverse range of researchers, students, and …

The fraction F of incident light absorbed by a photoreceptor of length l has traditionally been
given by F= 1-e− kl, where k is the absorption coefficient of the photoreceptor. Unfortunately …

Here, our objective is to examine how the jum** spider's eight eyes are structured, how
they function, and how they might have evolved. We will also review the intricate vision …

Many insect species have darkly coloured eyes, but distinct colours or patterns are
frequently featured. A number of exemplary cases of flies and butterflies are discussed to …
