Adult silver phase American Eel
A silver-phase American Eel in a northeastern river begins migrating downstream to the ocean to spawn in the Sargasso Sea. The migration can span hundreds of kilometers in freshwater rivers and thousands of kilometers at sea.

Eel airlift bypass prototype
Prototype design of an airlift developed at CAFL to transport downstream migrant eels through a bypass pipe and away from turbine intakes. The airlift design passes eels as well as a conventional siphon or gravity pipe.

Barred tiger salamander (paedomorph)
Barred Tiger Salamander Paedomorph, Cottonwood Lake Study Area, North Dakota. Some barred tiger salamanders never metamorphose and keep their larval features (e.g., gills, finlike tail) their whole lives as reproductively mature adults known as paedomorphs, which can grow to be 14 inches in length.

Grass carp larvae
These images show grass carp larvae from the Maumee River. Characteristics of larval grass carp include overall length (left), skeletal muscle development (center) and presence of an eye spot that lacks pigmentation (right; pigment starting to develop on lower eye).
