Summary
| Description |
English: This is a freshwater amphipod (/Hylallela azteca/ - Crustacea: Amphipoda) infected with the parasitic acanthocephalan (/Corynosoma constrictum/ - Acanthocephala: Polymorphidae) collected at Crescent Lake National Wildlife Refuge and photographed at Cedar Point Biological Station (University of Nebraska). As adults, these thorny headed worms are parasites of ducks. The eggs are eaten by the amphipods and the worm develops into an infective (orange colored) cystacanth larva. The whole amphipod is then eaten by a duck or other water bird and the worms mature in the small intestine of the definitive host. L. Duclos showed that the orane color is due to carotenes concentrated in the tissues of the cystacanth larva. 27/July/2018.
Español: Este es un anfípodo de agua dulce (/Hylallela azteca/ - Crustacea: Amphipoda) infectado con el parásito acantocéfalo (/Corynosoma constrictum/ - Acanthocephala: Polymorphidae) recolectado en el Refugio Nacional de Vida Silvestre Crescent Lake y fotografiado en la Estación Biológica Cedar Point (Universidad de Nebraska). Cuando son adultos, estos gusanos con cabeza espinosa son parásitos de los patos o otros aves en el agua. Los anfípodos se comen los huevos y el gusano se convierte en una larva de cistacanto infecciosa (de color naranja). Luego, un pato u otra ave acuática se come el anfípodo entero y los gusanos maduran en el intestino delgado del huésped definitivo. L. Duclos demostró que el color naranja se debe a los carotenos concentrados en los tejidos de la larva del cistacanto. 27/julio/2018. |
