Blennies are preyed upon by various marine predators, including larger fish species such as groupers, snapper, and bass. Some invertebrates, like octopuses and certain types of crabs, may also feed on blennies. Additionally, seabirds that dive for fish can target blennies when they are near the water's surface.
