Animals usually swallow using their tongue and throat. The northern leopard frog (Rana pipiens) uses its eyes. To swallow food such as a small cricket, it closes its eyes and retracts its eyeball into its body. These push into the pharynx and against the prey item, and regular retractions help force the food to the back of the oesophagus.
