Muddy waters: An assessment of the suitability of zygocardiac ossicles for direct age estimation in the Giant mud crab <i>Scylla serrata</i> Open
A fundamental characteristic of calcified structures commonly used for direct age estimation in animals is that new material is accreted cumulatively and preserved across ontogeny, thus allowing growth marks to be reliably observed and cou…
