A film series by Heinz Sielmann.
A second showing of Tournament of Dragons

The Galapagos Islands are famous for their lizards: the marine iguanas that have learned to look for food under water, the bigger land iguanas that have to compete against merciless drought, and the little lava lizards which are carnivorous. But fighting among their own kind over boundaries and breeding-places often disturbs their seemingly peaceful existence.
