Crocodiles engage in complex courtship behaviors that precede mating, which occurs in the water. During the breeding season, both sexes may produce loud roars to communicate, and males often use these vocalizations to establish territories and attract females.123

Courtship involves a variety of signals, including:
* Vocalizations: Beyond roaring, animals use various sounds to signal one another.12
* Physical displays: Individuals change their body profiles and use touch to interact.1
* Chemical signals: Glands located in the mandible and cloaca excrete oily substances that are believed to play a role in communication.12

Once courtship is successful, the male mounts the female's back. Both animals rotate their tails to bring their cloacae into contact, allowing for the intromission of the male's erectile organ. While all species reproduce sexually, it is worth noting that the American crocodile has been observed reproducing via parthenogenesis, a process where offspring develop without fertilization.1
