Giant Eels

The giant eel is a massive, flesh-eating, wall-climbing, air-absorbing, snakelike fish that can attack like a crocodile and live upwards of 100 years. So, of course, Zeb goes in search of two of the largest species. First, in New Zealand, Zeb hunts for the New Zealand longfin eel and goes fishing with the locals, who use a traditional technique to lure the legendary monster. Then, in the Solomon Islands, he'll look for the elusive giant mottled eel.
