Reproduction/ Development
Mating Behavior
The way in which American Bullfrogs mate is called amplexus. The male will lay on top of the female and wrap it's arms around the female's abdomen. The male releases it's sperm while the female releases it's eggs. Once the eggs are laid, the female will leave but the male will stay with the eggs to mate with the females once hatched.
Male Reproduction
Males reproductive systems contain three major organs, testes, the urine ducts and the cloaca.
Testes: Where the sperm is produced
The Urine Ducts: Carries the urine and sperm to the cloaca
Cloaca: Sperm and urine exit the body through the cloaca
