In 1992, living lampreys were found, and since then efforts have been undertaken to reverse the attempted eradication. Barriers put up to limit them have been taken down, and today their populations appear to be recovering. 2/2

Solenodons are a unique family of mammals. 73 million years ago, they diverged from shrews, moles, and hedgehogs. In the last 500 years, two solenodon species went extinct. Now there are just the Hispaniolan and Cuban solenodons. 📸: commons.wikimedia.org/wiki/F… 2/3
