Which Joe gave his name to ‘sloppy joes’? We look at five interesting sandwiches and their lexical origins.
An eye consisting of an array of numerous small visual units, as found in insects and crustaceans.Contrasted with simple eye
- ‘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.’
- ‘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.’
- ‘Flies, crabs, and other arthropods have compound eyes in which many, sometimes hundreds, of individual ommatidia, or unit eyes, gather visual information.’
- ‘Evidently the lenses act to focus light in a manner similar to the compound eyes of insects.’
- ‘The eyes may have permitted comprehension of the world in the same fashion as the similar compound eyes of living arthropods.’
- ‘Insect compound eyes contain light-sensitive receptors in which phototransduction takes place.’
- ‘Each compound eye is composed of nearly 28,000 individual units, and together the eyes cover most of the head.’
- ‘The eyes are usually simple, though one group has compound eyes.’
- ‘Either compound eyes were lost numerous times or very similar eyes evolved separately in multiple lineages.’
- ‘In addition to ocelli and compound eyes, some insects are quite sensitive to sounds, and their chemoreceptive abilities are astounding.’
- ‘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.’
- ‘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.’
- ‘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.’
- ‘Like the compound eyes of adult crustaceans, larval eyes contain several types of pigments.’
- ‘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.’
- ‘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.’
- ‘A close-up view of a male blue dasher dragonfly shows the many lenslets of the insect's compound 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.’
