Octopus and Grouper, or the eternal struggle between prey and predator. In the case of this encounter it is difficult to define who really is the prey and who the predator. In the video we made, below the coast and a few meters deep, we see two small specimens of Mediterranean grouper or Brown grouper, (Epinephelus marginatus) sharing the same environment and the same area with Common Octopus (Octopus vulgaris).

Initially we managed to spot the two groupers in apnea, after a few dives these two did not seem too disturbed by our invasive incursions, one immediately doubts that they are interested in something else. In fact, darkening between the holes, an octopus appeared shortly after and immediately put itself on the defensive, camouflaging itself from both the groupers and the divers..

Returning to the octopus and the grouper, octopuses represent the prey par excellence of the groupers of which they are greedy. In our case the octopus seems big enough not to worry about the two fish. The meeting was certainly fortuitous and occasional, but to be considered positively since the groupers had practically disappeared from our coasts. On this site we have often dealt with the subject and as far as possible we will continue to talk about it.
