The animal realm is full of predators and prey , with some predators being extraordinary killers . But there are many shipway to enchant a meal and many ways to delineate what makes a successful marauder .
So which animal is truly the best hunter ?
Dragonflies have many adaptations that make them excellent hunters, including compound eyes and wings they can move independently.
This is a deceptively complex inquiry , accord toMark Belk , an evolutionary ecologist at Brigham Young University . " There ’s so much interesting ecology and evolutionary biology tie up in this unsubdivided question , " he told Live Science . " Predation turn out to be the gum that holds everything together — this is how vitality passes through ecosystem . "
The most obvious way to go about the question of hunt down prowess is to consider an brute ’s snap rate — the identification number of time an animal successfully put down a repast out of all of its corporate attempts .
By this metric , it is n’t actually the metal money we most associate with hunting — such as lions , tigers , wolves and other big predators — that are the most successful . lion make a killroughly 30 % of the time , while tigers are successfulonly about 10 % of the time . alternatively , it ’s the relatively overlooked dragonfly that take in the title . These insect , along with their cousins the robber fly , have up to a 97 % catch pace , and theycan consume hundreds of mosquitoes a daylight .
Dragonflies have many adaptations that make them excellent hunters, including compound eyes and wings they can move independently.
Their success comes , in part , from their extraordinary visual sense . Dragonflies and their kin have compound eye that give them almost 360 degrees of flock , and their brains are equal to ofprocessing sensational information passing quickly , give up them to predict where target will move . And because they can move their fore wing and hind wings independently , snake feeder are adept aviator and can even surge backward .

But there are other definitions of hunting winner , Belk said . Typically , hunters flow into one of two camps : brute that actively prosecute and aggress their prey , and beast that lie in wait , relying on their forbearance to earn them a meal . In terms of sheer efficiency , something like a large python might deserve the summit , Belk said .
Archerfish can knock over prey by using a carefully aimed jet of water.
" A prominent snake like that can sit in one place and hold off and wait and waitress and waitress . And finally , when the ripe animal pass off by , they ’ll grab it and make a kill , " Belk said . " For these enceinte snakes , that might only happen two or three times a yr . "
Another fashion to draw shut the motion could be to study adaptability as a measure of attainment . Jason Fisher , a wildlife life scientist at the University of Victoria in Canada , said coyotes are the likely winners here , as they ’re up to of hunt alone or in a radical and of banquet on everything from moose calf to mouse . Their flexibility has helped themthrive in most habitat , include human cities . " Understanding what resources are available to you and exploiting them makes for an amazing predator , " Fisher said , adding that coyotes excel at " making use of whatever ’s at mitt . "
Otherwise , some species are simply so innovative that it ’s hard not to count them success . Archerfish — tropical fish aboriginal to the mangrove of Southeast Asia — can try the aloofness between themselves and an worm sitting on a leaf from below the water supply , and can then knock it downusing a cautiously aim jet of water . Across distances of 2 feet ( 65 centimeters ) or less , their purpose is closely 100 % accurate . Octopuses have been similarly successful at hunting outside their rude element : In improver to using their legendary camouflage , these cephalopods cantake to terra firma for small periods of timein pursuit of prey .
Out of all their attempts to capture prey, lions are successful only about 30% of the time.

Octopuses use their legendary camouflage and ability to briefly go on land to nab prey.
And which animal is the worst hunter ? Fisher said that , in some direction , that ’s an even hard question to answer . Every coinage that hunts is , by definition , successful , as it can confirm itself as a population . But in term of sheer oddity , Fisher told Live Science his ballot goes to the wolverine , which is consider a hunter but rely on scavenging during skimpy point .
" They ’re just so awkwardly shape , and their scheme is flakey , " Fisher say , noting that wolverines hunt down by getting into their prey ’s face and affright them with shrieking and other loud noises . " They basically say , ' If it mold , that ’s cool , and if it does n’t , I ’m out of portion , ' " he said .
