|Abstract:||Some parrotfishes have developed a unique capacity to form a mucous
envelope at night. Scarus dubius and S. perspicillatus are two Hawaiian species that
exhibit envelope-building behavior. Laboratory experiments indicate that envelope
formation is promoted by darkness, and is inhibited by constant light. The completed
envelope is a transparent, mucous cocoon surrounding the fish. A mass of
glandular tissue was found in the buccal cavity of S. dubius and S. perspicillatuS. It
is suggested that this tissue is the envelope-producing gland.
