While hunting underwater, platypuses store captured prey in cheek pouches to eat later on land. This adaptation prevents loss of food while surfacing or moving between feeding areas. Cheek pouches expand and contract to hold multiple prey items. They are flexible and waterproof, allowing platypuses to forage continuously. This behavior maximizes energy intake during short foraging periods. It also enables platypuses to feed young without constant trips. This is essential in rivers with patchy prey distribution.
Cheek pouches enhance foraging efficiency and energy management.
They allow platypuses to feed in bursts and transport food safely.
Underwater cheek pouches are rare among mammals.
