Most blennies are bottom-dwelling. Some species are predators and other have teeth specific for grazing algae off of rocks. Most lack a swimbladder which is an adaptation for many bottom dwellers. Diet: Some are herbivores, and others are crustacean feeders. Final Note: Blennies are bottom dwellers that generally eat bottom dwelling crustaceans or algae. Each species exhibits a specific diet preference - some are obligate herbivores, some are strict carnivores, and others are omnivores. There are a few species with venomous fangs that serve as defensive weapons. There are a few species of blennies that eat coral polyps, and a few others that bite the scales of fish.
