New Zealand’s longfin eels (Anguilla dieffenbachia)
The longfin eels of New Zealand are a unique and threatened species with a precarious future. They can take 20 or more years to reach maturity, and reproduce only once In their lives. Once they are mature they leave their freshwater homes and swim many miles out to sea where the eggs are laid and fertilized. They then drift back to New Zealand on the ocean currents, eventually swimming upstream to restart the life cycle.
These beautiful native parakeets were once widespread throughout New Zealand, but have now become very rare, and are under the protection of the NZ Department of Conservation. This is the Red-crowned species. Photographed at Mount Bruce.
