Marine Landlords
Red Groupers, which are prevalent along the coast of Florida, are the 'beavers' of the marine community. They find holes in the sea floor and excavate the loose sediment from them to make a home for themselves.
The openings become dream properties for corals, sponges, and sea anemones, as well as cleaner fish, crabs, and spiny lobsters seeking refuge from predators.
The fish meticulously maintain their holes, clearing away any stray sand or debris.
In return, the groupers get regular grooming sessions from the cleaner fish, a safe haven to attract mates, and, occasionally, an easy meal, the study says.
