The U.S. National Oceanic and Atmospheric Administration announced the discovery of a sea sponge which may be one of the world’s oldest living animals.
They can be found in elevations from sea level to 5,000 m (16,000 ft). They prefer warmer, tropical climates but are adaptable and can live in all but the most extreme environments. Lizards also exploit a number of habitats; most primarily live on the ground, but others may live in rocks, on trees, underground and even in water. [ 40 ]
