The structure and function of the eggshell of the leatherback turtle (dermoclzelys coriacea) from Malaysia, with notes on attached fungal forms

The structure of the eggshell of the leatherback turtle, Dermocheleys coriacea. conforms generally to that described for contemporary chelonians (Hirsch 1983;' Solomon and Watt 1985;8 Solomon and Tippett 198?9). It is composed of an inner organic membrane and an outer inorganic or mineral layer...

It is composed of an inner organic membrane and an outer inorganic or mineral layer of calcium carbonate deposited as aragonite.
