A Whooping crane chick is released into a temporary pen to acclimate before being released into the wild. Four of the endangered chicks, hatched and raised by their parents at the U.S. Geological Survey’s Patuxent Wildlife Research Center in Laurel, Maryland, were released on Necedah National Wildlife Refuge in Wisconsin.

Pallid sturgeon free embryos preserved at 3 days post hatch. Free embryos at this stage have only a rudimentary mouth, their pectoral fins are only beginning to develop, and they rely on a large yolk sac for food.
