| Definition | Tercera persona del singular (él, ella, ello; usted, 2.ª persona) del pretérito perfecto simple de indicativo de pedir. | (orden Phthiraptera) Cualquiera de más de 3000 especies de insectos ápteros adaptados para parasitar virtualmente todas las especies de mamíferos y aves, cuya sangre consumen, alojándose en el cabello del cuerpo y la cabeza. Su cuerpo está diseñado para este hábitat, con el primer par de patas modificado para permitir la sujeción al cabello. Son extremadamente fértiles, depositando las hembras hasta unos 200 huevos en los 30 días de su vida adulta. Tienen el cuerpo aplanado y de color oscuro o pardoamarillento. La infestación con piojos se denomina pediculosis, y provoca comezón, además de funcionar como vector para otras enfermedades —en particular el tifus— y provocar anemia en casos agudos. |
