Gulf sturgeon

The Gulf sturgeon is just one of hundreds of fish species threatened by the oil spill. Already considered a species at risk, the oil slick could potentially cover what remains of this animal's remaining habitat.

Even worse, sturgeon are currently preparing for their seasonal migration upstream to spawn. As oil reaches their congregation areas, the population could crash en masse.
