    • ‘The ommatidia of these two groups are the most similar of the major arthropod groups and compound eyes are common in many hexapods and crustaceans.’
    • ‘In common with many other insects, adult butterflies have antennae, compound eyes, three pairs of legs, a hard exoskeleton, and a body that is divided into three parts: the head, thorax, and the abdomen.’
    • ‘Evidently the lenses act to focus light in a manner similar to the compound eyes of insects.’
    • ‘Crustaceans that have apposition compound eyes as adults, like some crabs, may simply continue to use the larval design with few modifications.’
    • ‘Fiddler crabs, like their arthropod cousins the insects, have compound eyes.’
    • ‘The optical design of a compound eye that permits the smallest retinal radius is the apposition type, so it is not surprising that this is the optical plan used in all larval crustacean compound eyes.’
    • ‘These considerations lead to the interesting hypothesis that genes that code for myodocopid compound eyes were maintained during ostracod evolution in the absence of the eyes themselves.’
    • ‘Complementing the large compound eyes, locusts have three much smaller simple eyes or ocelli characterized by rapid signal transmission and high photic sensitivity but very poor spatial resolution.’
    • ‘Either compound eyes were lost numerous times or very similar eyes evolved separately in multiple lineages.’
    • ‘Each compound eye is composed of nearly 28,000 individual units, and together the eyes cover most of the head.’
    • ‘We are all familiar with the idea that there are strikingly different kinds of eyes in animals: insects have compound eyes with multiple facets, while we vertebrates have simple lens eyes.’
    • ‘The nervous system and sensory system are simple, although some species vibrate their compound eyes to gather more visual information.’
    • ‘But all sighted insects have compound eyes, consisting of a mosaic of tube-shaped optical lens systems, with photoreceptors at the base of each tube.’
    • ‘Insect compound eyes contain light-sensitive receptors in which phototransduction takes place.’
    • ‘The eyes are usually simple, though one group has compound eyes.’
    • ‘Flies, crabs, and other arthropods have compound eyes in which many, sometimes hundreds, of individual ommatidia, or unit eyes, gather visual information.’
    • ‘Like the compound eyes of adult crustaceans, larval eyes contain several types of pigments.’
    • ‘In addition to ocelli and compound eyes, some insects are quite sensitive to sounds, and their chemoreceptive abilities are astounding.’
    • ‘A close-up view of a male blue dasher dragonfly shows the many lenslets of the insect's compound eyes.’
    • ‘The eyes may have permitted comprehension of the world in the same fashion as the similar compound eyes of living arthropods.’
