The rivers of central Portugal have been invaded, and densely populated, by the Louisiana crayfish, Procambarus clarki, which looks like a freshwater lobster about 12 to 14 cm long. The otters of these rivers can easily catch and subdue these crayfish.

For the crayfish, assume low handling time, very high encounter rates, and high energy content.
