the eye type of insects and crustaceans, which can have up to 1000 or more light-detecting, focusing ommatidia.
set upon short stalks in crayfish; contains over 2,000 tiny lenses used to detect light and movement; form relatively poor visual images
A large grouping of light gathering organs that allow the insect to detect color and motion. For most insects, resolution is not very good.
Found in many but not all arthropods, a compound eye is composed of a large number of small, closely packed simple eyes (ommatidia), each with its own lens and nerve receptors.
an aggregation of visual units known as ommatidia, consisting of a lens, cone and retina or group of light sensitive cells. Often look hexagonal in shape when crowded together but are circular when only a few
An eye made up of many separate units, each with its own surface area, lens, and optic nerve fiber. The images collected by all the parts of a compound eye are integrated in the animal's brain. Most invertebrates -- crustecea such as crab and shrimp, and insects such as dragonflies and bees -- have compound eyes. See Anatomy of a Compound Eye for more details.
paired aggregations of separate visual elements known as ommatidia that are located on the insect head. Each pair of ommatidia corresponds with a single facet of the cornea. View image
in insects and some crustaceans: composed of many light-sensitive elements each forming a portion of an image
a visual organ found in certain arthropod s (some insect s and crustacean s)
the eye that most insects and some crustaceans have, made up of several separate light-sensitive parts.
These are the pair of image forming optical units on either side of the compound eye. They are made of many optical subunits called ommatidia (singular ommatidium).
A large eye made up of many separate units.
Type of eye subdivided into many individual, light-receptive parts, such as that found in insects, crustaceans, etc.
An eye that's made up of many tiny, simple eyes that work together to form an image.
Eye formed of multiple lens components
an eye made up of many individual elements
A type of multifaceted eye in insects and crustaceans consisting of up to several thousand light-detecting, focusing ommatidia; especially good at detecting movement.
An eye that consists of many visual units, each having its own lens. Messages received from the different units together produce a large field of view that is not sharp in detail. Insects and crustaceans have compound eyes.
Eye composed of many units, each with a lens or facet.
An eye with many elements, common in insects, in which each element is visible as a hexagonal facet.
Insects (like butterflies and moths) have compound eyes. These eyes are made up of many hexagonal lens/corneas which focus light from each part of the insect's field of view onto a rhabdome (the equivalent of our retina). An optic nerve then carries this information to the insect's brain. They see very differently from us; they can see ultraviolet rays (which are invisible to us).
A compound eye is a visual organ found in arthropods such as insects and crustaceans. It consists of one to thousandshttp://entomology.unl.edu/ent801/vision.html of ommatidia which are tiny independent photoreception units that consist of a cornea, lens, and photoreceptor cells which distinguish brightness and color. The image perceived by the arthropod is a combination of inputs from the numerous ommatidia, which are oriented to point in slightly different directions.
