Abstract
Epidermal cell proliferation in four bottlenose dolphins, Tursiops truncatus, was studied using radioactively labelled thymidine. The epidermal proliferation index (PI) of 7.4 ± 0.6% is 1.3 to 1.9 times higher than that reported for terrestrial mammals. The size of the proliferative pool, a function of the ratio of basal to surface area of the epidermis, was found to be 13.1:1. These two factors combine to give a large proliferative capacity, which contributes to the unusual thickness of the epidermis of Tursiops.Keywords
