Keystone species mussel population explodes uncontrollably, driving out most other species. These creatures need not be apex predators. Sea stars are prey for sharks, rays, and sea anemones. Sea otters are prey for orca. The jaguar, whose numbers in Central and South America have been classified as near threatened, acts as a keystone predator by its widely varied diet, helping to balance the mammalian jungle ecosystem with its consumption of 87 different species of prey. The lion is another keystone species. Keystone mutualists are organisms that participate in mutually beneficial interaction and the loss of which would have a profound impact upon
Asiatic softshell turtle such as Asia and India. It are one of the few species harvested where they naturally reside, providing food for the people in the surrounding areas. They are an important food in the Sarawak culture. These areas have a sparse variety of food. However, the exploitation and trade of "Amyda cartilaginea" may be hurting the turtle's population. Millions of Asiatic soft-shells are shipped around these regions every day, causing more to be shipped than what is produced in their habitat. The United States has some regions where these turtles reside, and used to participate in trade of the Asiatic soft-shell
