(0-2.5 m) shelf had juveniles less than 100 mm in 

 shell length; however, these were rare in the shelf 

 environment, and few juveniles less than 160 mm 

 were found on the shelf between 2.5- and 15-m 

 depth. None of the juveniles on the bank were near 

 the 227-mm average length of adults on the shelf, 



but many juveniles collected in deeper water were 

 close to adult size. 



Other differences were observed in the shells of 

 queen conch from bank and shelf regions. Juvenile 

 conch from the bank differed from shelf juveniles 

 because of thicker shells and longer lateral spines
