Invasive Lionfish Removal
The invasive red lionfish (Pterois volitans) waits to be hauled to the surface, where it will eventually be used by NOAA to conduct lab studies on lionfish reproductive biology, age, and growth.

Invasive Lionfish Removal
A scientist from the North Carolina Aquarium removes an invasive red lionfish (Pterois volitans) found in coastal North Carolina's hard bottom habitat, to prevent ecological impacts due to its predation and competition with native fishes.

Great Blue Heron
Great Blue Herons are found throughout much of North America, but are always associated with water. Because they fish by sight, they need relatively shallow water. Release of too much water through the canals north of the Everglades can interfere with their ability to find food.

Amakihi Honeycreeper
During the past decade populations of this honeycreeper have begun to rebound at lower elevations on most of the main Hawaiian Islands, in spite of high prevalence of infection with avian malaria.
