Nature never ceases to amaze. You may have heard of some fish that miraculously can walk on land. However, have you ever heard of a fish that can climb walls? Cave-diving experts in Ecuador recently stumbled upon that very scene, recording the first scientific evidence ever that proves this amazing behavior is real.
Scientists have discovered what are called "dead zones" in the tropical North Atlantic, and they could potentially lead to mass fish kills, according to new research.
An army of 3,000 strong and counting is building in a lake in Boulder, Colorado, and the potential impact of this invasive exotic fish has conservationists on edge.
It is no secret that in the midst of climate change, coral reefs around the world are suffering.
