All chameleons are primarily insectivores and feed by ballistically projecting their tongues, often twice the length of their bodies, to capture prey. They can change colour to match their surroundings and often climb through trees with a swaying motion, probably to mimic the movement of the leaves and branches they are surrounded by. Īn ambush tactic done by wolves or lions can be considered a tactic by cooperative hunters, where a flock of a particular species hunts for their prey in a group so they can obtain much larger prey (L15-BSCI361-Predation).Ī chameleon's tongue striking ballistically at foodĬhameleons (family Chamaeleonidae) are highly adapted as ambush predators. Several species of Felidae (cats) and snakes have vertically elongated (slit) pupils, advantageous for nocturnal ambush predators as it helps them to estimate the distance to prey in dim light diurnal and pursuit predators in contrast have round pupils. The fish faces into the current, waiting for prey to drift by.
The deep-sea tripodfish Bathypterois grallator uses tactile and mechanosensory cues to identify food in its low-light environment. In addition to the assessment aspect, sometimes when the predator cannot fit the prey into their mouth, they will 'put the prey back or leave it alone this can be defined as "gape limitation" and typically make predators be seen as generalists (L15-BSCI361-Predation). They prefer to strike prey that is both warm and moving their pit organs between the eye and the nostril contain infrared (heat) receptors, enabling them to find and perhaps judge the size of their small, warm-blooded prey. For example, pit vipers prey on small birds, choosing targets of the right size for their mouth gape: larger snakes choose larger prey. They have evolved a variety of adaptations that facilitate this assessment. They need to detect the prey, assess it as worth attacking, and strike when it is in exactly the right place. Īmbush predators must time their strike carefully. Many nocturnal ambush predators like this leopard cat have vertical pupils, enabling them to judge distance to prey accurately in dim light. Crab spiders, similarly, are coloured like the flowers they habitually rest on, but again, they can lure their prey even away from flowers. The orchid mantis actually attracts its prey, pollinator insects, more effectively than flowers do. įlower mantises are aggressive mimics, resembling flowers convincingly enough to attract prey that come to collect pollen and nectar. There is however some controversy about whether this is a true case of wolf in sheep's clothing mimicry. The zone-tailed hawk, which resembles the turkey vulture, flies among flocks of turkey vultures, then suddenly breaks from the formation and ambushes one of them as its prey. Similarly, some reptiles such as Elaphe rat snakes employ caudal luring (tail luring) to entice small vertebrates into striking range. Its tongue bears a conspicuous pink extension that resembles a worm and can be wriggled around fish that try to eat the "worm" are themselves eaten by the turtle.
The alligator snapping turtle is a well-camouflaged ambush predator. This strategy is called aggressive mimicry, using the false promise of nourishment to lure prey. Many ambush predators actively attract their prey towards them before ambushing them. The orchid mantis, Hymenopus coronatus, mimics a rainforest orchid of southeast Asia to lure its prey, pollinator insects. Different ambush predators use a variety of means to capture their prey, from the long sticky tongues of chameleons to the expanding mouths of frogfishes.Īmbush predation is widely distributed in the animal kingdom, spanning some members of numerous groups such as the starfish, cephalopods, crustaceans, spiders, insects such as mantises, and vertebrates such as many snakes and fishes. Nocturnal ambush predators such as cats and snakes have vertical slit pupils helping them to judge the distance to prey in dim light.
The predator then uses a combination of senses to detect and assess the prey, and to time the strike. The ambush is often opportunistic, and may be set by hiding in a burrow, by camouflage, by aggressive mimicry, or by the use of a trap (e.g. Unlike pursuit predators, who chase to capture prey using sheer speed or endurance, ambush predators avoid fatigue by staying in concealment, waiting patiently for the prey to get near, before launching a sudden overwhelming attack that quickly incapacitates and captures the prey. A female goldenrod crab spider ( Misumena vatia) ambushing the female of a pair of mating fliesĪmbush predators or sit-and-wait predators are carnivorous animals that capture or trap prey via stealth, luring or by (typically instinctive) strategies utilizing an element of surprise.
