Definição: 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.
Definição: A rock formed by subjecting any rock type (including previously-formed metamorphic rock) to different temperature and pressure conditions than those in which the original rock was formed. These temperatures and pressures are always higher than those at the Earth's surface and must be sufficiently high so as to change the original minerals into other mineral types or else into other forms of the same minerals (e.g. by recrystallisation).
Definição: 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)
