The Blennidae family includes marine fish that are generally small and elongated, known for their great adaptability to coastal and reef environments. These fish often have serpentine bodies, well-developed pectoral fins, and a protractile mouth, allowing them to feed efficiently on small invertebrates and algae. Highly agile, they inhabit crevices, rock holes, and shallow coral reefs, where they find refuge from predators. They are widely distributed in tropical and temperate waters worldwide.
