Yacare Caiman and a piranha. would love to capture the feel of this somehow.
The Yacare Caiman (Caiman yacare) is extremelly common in the Pantanal, due in large part to the abundance of fish, their main food. There's an estimate 30 million caimans in the Pantanal. During the dry season they tend to concentrate in great numbers around drying lakes, where prey is easily captured.
