The spring and summer foods of bullfrogs (Rana catesbeiana and R. grylio) were determined from examination of stomachs of 425 specimens collected in three coastal areas of Louisiana.

Bullfrogs from the coastal marshes are omnivorous although chiefly carnivorous. Crustaceans make up over 50 per cent of their spring and summer diet. Their major food is crabs which occurred in 55 per cent of the stomachs and formed 51 per cent of the total volume of consumed food. This is in marked contrast to findings in more northern states, where crawfish and insects form the principal foods. Other major foods consumed by coastal bullfrogs are crawfish, fish, and insects.
