We already know that parrotfish (Labridae: Scarini) are large (and beautiful!) fishes that play critical functional roles in reef environments when they feed, which in their case, we call “ grazing ”. Parrotfishes spend their day biting off bits and chunks of algae and other benthic organisms with their beak-like teeth. However, macroalgae may not be their preferred dish, they seem to like smaller diet items then what has been previously assumed. Because of this new finding, they have been recently reclassified as microphagous (“eaters of tiny particles”) (Clements et al., 2016), which by no means diminishes their importance in shaping the reef community. In other words, their nutrition comes from protein-rich autotrophic microorganisms, which in their turn are associated with macro organisms. By eating microorganisms, parrotfish affects the structure and composition of benthic communities by maintaining algae free corals.  Unfortunately, fishing pressure on parrotfishes has grown in t

Every time you go to a different beach, the most prudent thing to do is asking local people where the safe places to swim are (places with no currents, for example). It is very likely that you would ask people somehow involved with the sea at that particular beach, such as lifeguards, surfers, and fishermen. The reason is obvious: since they are used to the local environment, they would know the risks. The same is true when researching any specific characteristic of a given area. Sometimes, when you want to understand specificities of a place, the best option is to ask local people about its characteristics and dynamics. When living in a place and depending directly on its resources, people learn how to deal with things available at the place. As these people spend time on their daily activities, they also have more opportunities to observe and accumulate knowledge of the surrounding area. Gathering this local ecological knowledge (LEK) is a good way to learn about local features wit
