LONDON, England (Reuters) -- Choosy Antarctic female fur seals go to great 
lengths to find the right mate.

While males prefer to stay put and wait to be chosen, females are more 
selective and prepared to travel to find an ideal, genetically diverse partner 
to father their pups.

"Many mammals have mating systems that were traditionally viewed as being 
dominated by males fighting each other for the right to mate with passive 
females," said Dr Joe Hoffman of the University of Cambridge in England.

"So it's not only remarkable to find that female fur seals are choosy, but this 
also suggests that female choice may be more widespread in nature than we 
previously thought."

Hoffman and scientists from the British Antarctic Survey (BAS), who reported 
their findings in the science journal Nature on Wednesday, discovered the 
unusual mating patterns while studying a colony of the seals on the island of 
South Georgia.

To avoid inbreeding with the less adventurous males, female seals would travel 
up to 35 meters to find a fitter mate to give the next generation the best 
chance of surviving.

Hoffman and his team believe the females size up potential mates by assessing 
their physique, behavior and even their smell.

"The behaviors that we observe will impact upon the genetic diversity of fur 
seal populations and may have helped them recover so successfully from near 
extinction only 100 years ago," said Hoffman.

"This could in turn affect how well they respond to future challenges such as 
climate change," he added in a statement.
