Lemon sharks can be identified by their two equally-sized, large dorsal fins. Juveniles spend most of their early years sheltered in mangrove habitats where few large sharks can swim, expanding their range as they grow. Some adult lemon sharks form loose aggregations made up of around 20 similarly sized sharks of the same sex, and tend to spend the daytime in deeper waters, coming into shallower habitats at night. Females return to shallow mangrove nurseries to give birth, and some adults make long seasonal migrations.
