Individual frogs have been observed to change their sex organs from female to male. This likely occurs when the population does not have enough males to allow procreation and is accomplished when a chemical trigger activates the sex gene to disintegrate the female organs and develop the male ones.

for-science-sake:

The Butterfly Snail (Limacina helicina) is a species of predatory swimming marine snail. They are a keystone species within Arctic pelagic ecosystems and are currently under serious threat.

They are being impacted by Ocean Acidification, due to pollution the ocean waters are becoming too acidic for survival. The corrosive waters off the West Coast of the U.S are dissolving the shells of these unique creatures and inevitably killing them. The decline of these will have major flow on effects to major marine ecosystems.
