Once Elaine leaves the freshwater estuary, she will disappear completely from human view.

As Elaine leaves fresh water for the ocean,she undergoes a shocking metamorphosis.Her eyes enlarge by about ten times,her skin gets thicker,and her fins get larger.These are most likely adaptations for their upcoming ocean travel,and Elaine seamlessly makes the transition from fresh to salt water,which would be toxic for most other fish.Once Elaine leaves the mouth of the fresh water streams,she will disappear completely from human view.No one has witnessed,or been able to follow,an adult eel on their migration,nor do we know how deep they spawn.
