I'm specifically asking about animals that use a hunting strategy revolving around hanging around cadavers to attack animals attracted to the cadaver, or even leaving part of their catches out to lure scavengers.
Saltwater crocodiles in Australia are reputed to do this; storing meat under water and later eating the fish and crustaceans that are attracted.
Having trouble finding a good source for this.
