The slime coat (also fish slime, mucus layer or slime layer) is the coating of mucus covering the body of all fish. An important part of fish anatomy, it serves many functions, depending on species, ranging from locomotion, care and feeding of offspring, to resistance against diseases and parasites.[1]
The mucin making up the slime coat is secreted by goblet cells in the fish's epidermis.[2] The slime contains a variety of antimicrobial peptides and other antimicrobial components such as lysozyme and C-reactive protein.[3][4] It contains mycosporine-like amino acids to protect from ultraviolet radiation.
