Definition: overall repetitive or reflective pattern in the body of one individual of this taxon. eg: bilateral symmetry, rotational symmetry, radial symmetry
Definition: Mouthparts modified into long or short, sclerotized piercing devices that are used to penetrate the host/prey/substrate to gain access to food, and liquids are transported through the food canal with the aid of a pressure gradient created by a sucking pump.
Definition: The plain formed by the large amounts of silt and sediment, picked up as a glacier erodes the underlying rocks as it moves slowly downhill, and at the snout of the glacier, meltwater can carry this sediment away from the glacier and deposit it on a broad plain. The material in the outwash plain is often size-sorted by the water runoff of the melting glacier with the finest materials, like silt, being the most distantly re-deposited, whereas larger boulders are the closest to the original terminus of the glacier.
Definition: A group of species that exploit the same food resources, and/or use the same feeding or foraging methods. http://en.wikipedia.org/wiki/Guild_(ecology)
