The team of marine biologists based their conclusions on a study of Antarctic krill, a form of plankton eaten by penguins and seals after finding marked differences in the distribution of the vital food source.
Andrew Brierley, from the University of St Andrews' School of Biology Gatty Marine Lab, said hunting strategies closely match the natural distributions of plankton and follow a set pattern of movement.
"Predators often hunt by making long initial journeys into a new feeding area -- think of catching a bus in to a new town to look for a restaurant," he said in a statement released by the university Wednesday.
"This is followed by a series of smaller jumps to harvest the prey in that region, like walking from the chip shop to the burger van in the same town.
"Once all the prey is consumed in the first location, predators then move on in a long jump in search of a new feeding location -- a bit like getting a taxi home to raid the fridge after closing time (at the pub)."
The method, without the British-specific cultural analogies, is called "The Levy Walk", which scientists believe could help such animals survive in a harsh environment where the location of food sources is not always predictable.
"Predators using Levy search strategies locate food 14 percent more efficiently than random hunters and this might give them the edge in the competitive natural world," Brierley added.
The year-long St Andrews research -- details of which will be published in the journal Nature Thursday -- was part of a British Atlantic Survey study into sea-living prey around the remote South Atlantic Ocean island of South Georgia.
The Levy method has been a well-established mathematical formula applied to the foraging patterns of a range of birds and land animals.
But a Canadian research scientist questioned its accuracy last October, claiming technical mistakes in data collection and methodology that may have tainted results of previous studies.
