Interaction between Halobatrachus didactylus and Anguilla anguilla: What happens when these species occur in sympatry?
The Lusitanian toadfish, Halobatrachus didactylus, and the European eel, Anguilla anguilla, are benthic fish species, which occur in sympatry in the southern Iberian Peninsula and north-west Africa. The consequences of this sympatry were evaluated through the analysis of distribution, abundance and...
