Abstract
The Arabian Gulf catfish (Arius thalassinus, Rüppell) secrete a thick layer of proteinaceous material when threatened or injured. The chemical and pharmacological properties of this material indicate that it may promote the healing of wounds. These studies suggest that the abrupt secretion of mucous-like gel in response to a perceived hazard is an externally expressed defense response; the secretion may have a primary function in healing injury beyond the commonly postulated roles of deterring predators or facilitating escape.
