| The exocuticle is the only other layer produced before ecdysis begins (Stage D1) (and is calcified after ecdysis has ended). These cells apparently secrete the pharyngeal cuticular intima, consisting of three layers: the lamellate endocuticle, the exocuticle with trabeculae-bound spaces and the thin epicuticle lining the luminal surface. Grading of shell disease severity (in a total of 76 animals) included 3 levels by visual observation: mild (grades I and II) epicuticular erosion and erosion into the exocuticle, medium (grades III and IV) erosion into the striated endocuticle, the thin-lamellar endocuticle and erosion into the pseudomembrane and severe (grade V) total erosion of the cuticle and ulceration of the underlying cuticular epithelium, respectively, according to Smolowitz et al. |
