A basic morphological plan of organisms that have their body parts arranged around a central axis. Such organisms tend to be circular or cylindrical in shape, e.g., a coral polyp, or have projections around a central disc, e.g., starfish .
Industry:Natural environment
A device that receives electromagnetic radiation and converts it into a signal that can be recorded and displayed as numerical data or as an image.
Industry:Natural environment
A layer of calcium carbonate that grows outside corallite walls.
Industry:Natural environment
A periodic environmental signal that entrains a biological rhythm. For example, a cycle for a circadian rhythm, but may also be a temperature or even social cycle.
Industry:Natural environment
A troughlike depression with vertical to overhanging walls which cut across the reef front at right angles.
Industry:Natural environment
An elongated tubular organ of varying use and form, usually associated with the oral region of many invertebrates.
Industry:Natural environment
Energy that travels through space in the form of waves. The highest frequencies in the spectrum of electromagnetic radiation are gamma-rays; the lowest frequencies are radio waves. All electromagnetic radiation travels at the speed of light. Shorter wavelength radiation (eg, ultraviolet) carries more energy and is likely to be more harmful to living tissue.
Industry:Natural environment
Of or pertaining to a mantle, especially to the mantle of mollusks.
Industry:Natural environment
Reproduction without fertilization; the development of an unfertilized ovum, seed, or spore. It occurs naturally in several species and may also be induced artificially by chemical or mechanical means.
Industry:Natural environment
The collection of information about an object or event without being in physical contact with the object or event. Remote sensing is restricted to methods that record the electromagnetic radiation reflected or radiated from an object, which excludes magnetic and gravity surveys that record force fields.
