Turtle crab

The turtle crab is an animal that inhabits the beaches of Ember Island.

History
After Fire Lord Zuko went to see his father in prison for advice regarding the Yu Dao crisis, Ozai mentioned that during a trip to Ember Island, when Zuko was just a boy, they saw a hawk trying to catch a turtle crab and Zuko ran over to it. He grabbed the turtle crab in his arms, but soon realized he was starving the hawk. Before he could make a decision, a giant wave washed them all out to sea.
