The migratory eel, Anguilla rostrata, is born and lives the juvenile (immature) part of its life in a freshwater environment, but then migrates thousands of miles through the ocean as an adult in order to breed. These eels are known to regulate their internal water and salt balance. What adaptations would you expect this eel to have in order to transition from fresh water to salt water at these two life stages The adult eels would be better at removing salt from their bodies compared to juveniles. The adult eels would spend energy keeping salt in their bodies. The juvenile eels would spend energy keeping water in their bodies. The juvenile eels would be better at removing salt from their bodies compared to adults.
