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 ...
Barracudas are scavengers, and may mistake snorkelers for large predators, following them in hopes of eating the remains of their prey. Swimmers have been reported being bitten by barracuda, but such incidents are rare and possibly caused by poor visibility. Barracudas may mistake objects that glint and shine for prey. [6]
Amphipoda (/ æ m ˈ f ɪ p ə d ə /) is an order of malacostracan crustaceans with no carapace and generally with laterally compressed bodies. Amphipods (/ ˈ æ m f ɪ p ɒ d z /) range in size from 1 to 340 millimetres (0.039 to 13 in) and are mostly detritivores or scavengers.
Barracudas are ferocious, opportunistic predators, relying on surprise and short bursts of speed, up to 27 mph (43 km/h), [13] to overtake their prey. Adults of most species are more or less solitary, while young and half-grown fish frequently congregate. Barracudas prey primarily on fish (which may include some as large as themselves).

Populations of large predatory fish in the global oceans were estimated to be about 10% of their pre-industrial levels by 2003, [1] and they are most at risk of extinction; there was a disproportionate level of large predatory fish extinctions during the Cretaceous–Paleogene extinction event 66 million years ago. [2]
The mangrove snapper feeds mostly on small fishes, crustaceans (such as crabs and shrimp), cephalopods, gastropods, polychaete worms and some planktonic items (including copepods and amphipods). [ 3 ] [ 2 ] [ 4 ] It was also observed as systematically waiting under a maternal colony of buffy flower bats , for falling bats near the entrances of ...
They are generalist scavengers and predators of small animals. The name "ghost crab" derives from their nocturnality and their generally pale coloration. [1] [2] They are also sometimes called sand crabs, though the name refers to various other crabs that do not belong to the subfamily.
