Mucus, amphibians

Amphibians have mucus glands over their whole body to provide the mucus needed to keep their skin moist, and fields of granular glands that secrete alkaloid toxins. In addition to these general glands, salamanders possess glands... 

Aquatic frogs and toads probably need less toxin for defense than terrestrial forms. The compounds in the frogs mucus are thought to be neuroleptic, blocking dopamine receptors. They also possibly are antibacterial and aid wound repair, and they are known to elevate the level of prolactin, the amphibian Juvenile hormone (Barthalmus and Zielinski, 1988). 

Glyeoproteins in amphibians have not been yet extensively analyzed, although it is well known since longtime that egg jellies or skin mucus are carbohydrate-rich materials. The integumentary mucins from Xenopus laevis have been investigated by molecular cloning in order to examine the organization of the polypeptide backbone [20-22].
