Descrição: Immature (yellow-stage) Anguilla spp. normally have small eyes, while mature (silver-stage) eels develop large eyes during the migration to deep offshore waters prior to breeding. However, under certain unusual conditions, immature anguillids may develop large eyes. During investigation of the ichthyofauna of Elevenmile Creek, a small, dark colored stream in western Florida, we discovered a large-eyed population of immature Anguilla rostrata. At Cantonment (Escambia Co., Florida), Elevenmile Creek receives paper mill effluent which drastically reduces light penetration in downstream waters from the outfall to the mouth in Perdido Bay.
