Why does the fin whales have throat grooves?

The throat grooves (ventral pleats) expand when feeding, allowing a large volume of water and prey (e.g. krill, small schooling fish) to enter the buccal cavity (mouth). The grooves are contracted and the water forced out, trapping the prey in the hairy fringe of the baleen. The prey is then swallowed.
