| morula-like cells in photo-symbiotic clams harboring zooxanthellae. | symbiosis is observed between zooxanthellae, symbiotic dinoflagellates, and giant clams and related clams which belong to the families tridacnidae and cardiidae. we have previously shown that a photo-symbiotic clam tridacna crocea has three types of hemocytes, the eosinophilic granular hemocyte with phagocytic activity, the agranular cell with electron lucent granules, and the morula-like cell with large (ca. 2 mum in diameter) colorless granules. the function of the morula-like cell is not clea ... | 1998 | 18465996 |
| morphology of the symbiosis between corculum cardissa (mollusca: bivalvia) and symbiodinium corculorum (dinophyceae). | light and transmission electron microscopy of tissues of the symbiotic clam corculum cardissa (l) showed that a symbiotic dinoflagellate, symbiodinium corculorum (trench), is found predominantly in the mantle and the gills. the data suggest that in c. cardissa the algae are located in a zooxanthellal tubular system that is associated with the hemocoel and is similar to that seen in tridacnine ("giant") clams. the algae occur within the lumen of the tertiary tubules and are thus separated from th ... | 2001 | 11441975 |
