Scavengers are animals that consume dead organisms that have died from causes other than predation or have been killed by other predators. [1] While scavenging generally refers to carnivores feeding on carrion, it is also a herbivorous feeding behavior. [2] Scavengers play an important role in the ecosystem by consuming dead animal and plant ...
Scavengers, organisms that only eat organisms found already dead, are not predators, but many predators such as the jackal and the hyena scavenge when the opportunity arises. [ 9 ] [ 10 ] [ 5 ] Among invertebrates, social wasps such as yellowjackets are both hunters and scavengers of other insects.
Albatrosses are both predators and scavengers. So, their diet primarily consists of fish, squid, octopus, crustaceans, and carrion, which is the flesh of dead creatures.
In various regions of Africa, the dynamic interplay of vultures and predators such as lions, cheetahs, hyenas, and jackals significantly influences the continent's food web. These avian scavengers actively engage in competition with these predatory animals for sustenance, meticulously tracking their hunting activities. [25]
Scavengers are not typically thought to be detritivores, as they generally eat large quantities of organic matter, but both detritivores and scavengers are the same type of cases of consumer-resource systems. [6] The consumption of wood, whether alive or dead, is known as xylophagy.
"The are several reasons why a pterosaur would be at the water surface, including drinking and hunting for food itself," Brown added. Modern crocs are both active predators and scavengers.
The debate about whether Tyrannosaurus was an active predator or a pure scavenger, however, is as old as the debate about its locomotion.Lambe (1917) described a good skeleton of Tyrannosaurus ' s close relative Gorgosaurus and concluded that it and therefore also Tyrannosaurus was a pure scavenger, because the Gorgosaurus teeth showed hardly any wear.

Whether eating live prey or carrion, the wolverine's feeding style appears voracious, leading to the nickname of "glutton" (also the basis of the scientific name). However, this feeding style is believed to be an adaptation to food scarcity, especially in winter. [48] The wolverine is also a powerful and versatile predator.
