One 3sec blast of the seamoth's shocking defense perimeter module upgrade sends those Leviathan's running. if it grabs the seamoth, hold that charge button till it's just about to take a bite and it will release you and swim for the dunes. I've even tried chasing them to finish the kill but they do swim away rather rapid. 'Don't Fear the Reaper' ;o)
