LION-FISH HUNGRY BEAUTIFUL DISASTER

Indigenous to the Indo-Pacific Ocean Pterois,commonly known as the Lion-fish, is slowly wrecking havoc in the calm waters of the Great Caribbean.
Several hypotheses run around the reason of how this fish first appeared in the Caribbean, but the reality of the problem is that this hungry firey fish has no direct predators and with its ravenous stomach is currently feeding on several local juvenile fish.
This is a normal day in the life of the Lion-fish: surrounded by a huge buffet of easy-access food.This extranjero has found heaven feasting in foreign waters; lets cross our fingers and hope Mother Nature steps in to save the local fish and restore the delicate balance.

THE WALKING FISHERMAN OF THE SEA

Not all fishermen exist above the surface of the ocean. If you look below, there is a fish that is terrible at swimming due to his short and fat fins which don’t allow him to swim; so he literally walks along the ocean floor. All the other fish laughed at him and made fun of his attempt to produce stylish aquatic movements. To avoid being teased he hid amongst the rocks; away from the humiliation that his pitiful body encouraged. Amid the rocks he felt sad, lonely and even hungry because he wasn’t able to catch food like the other fish. Surrounded by these mixed feelings he looked up and to his astonishment his delicious food was swimming right above him just waiting to be gobbled up. He then realized that his main dorsal fin is actually an awesome weapon that he can use like a fishing rod, and by just dangling it out from behind the rocks he can trick unsuspecting prey. His friends saw his adaptive brilliance of how he walks and uses his dorsal fin as a protractible rod and they no longer laughed at him, but instead saw him as a fantastic fish. They nicknamed him “the walking fisherman”, and if you ever find yourself diving, look carefully amongst the rocks for a small yellowish to purple flat, triangular fish with his fishing rod stretched out, and know that you are in the presence of an adaptive genius.
