If you think a fish out of water would be easy to catch, you haven’t encountered the Pacific leaping blenny.
This acrobatic, slippery little fish can be found hopping and climbing around the rocky coasts of Guam. A diminutive 1½ to 3 inches in length, it spends almost all of its time on land — a curious and unique lifestyle among marine fish. To navigate its rocky habitat, the blenny has developed a tail-twisting move that allows it to leap from rock to rock with impressive distance and agility.
