Other live animals, up to nearly their own size, have been observed to be seized predaceously and dropped in flight. Among these are rock hyraxes, hares, marmots and, in one case, a 62 cm (24 in) long monitor lizard. [14] [38] Larger animals have been known to be attacked by bearded vultures, including ibex, Capra goats, chamois, and steenbok. [14]
The question of why prey animals stot has been investigated by evolutionary biologists including John Maynard Smith, C. D. Fitzgibbon, and Tim Caro; all of them conclude that the most likely explanation given the available evidence is that it is an honest signal to predators that the stotting animal would be difficult to catch. Such a signal is ...
Anhingas stalk fish underwater, mainly where there is some vegetation. Once they locate their prey, they partly open their bill and stab the fish swiftly. For larger fish, they use both their jaws; for small fish they may use only the lower jaw. [11] If the fish is too large to forage, the anhinga stabs it repeatedly and then lets it go. [30]

Wild animals can experience injury from a variety of causes such as predation; intraspecific competition; accidents, which can cause fractures, crushing injuries, eye injuries and wing tears; self-amputation; molting, a common source of injury for arthropods; extreme weather conditions, such as storms, extreme heat or cold weather; and natural disasters.
Sloths may be hosting entire ecosystems in their thick, dense fur, and algae growth on sloths can grow so great that it tinges their fur green. The video above from the Natural History Museum in ...
