[3] Like other crustaceans, lobsters have a hard exoskeleton which they must shed in order to grow, in a process called ecdysis (molting). After copulation, spermatozoa are stored by the female for several months until oviposition and fertilization occur (Aiken and Waddy, 1980). Using satellite tags, we tracked two ovigerous females from Grand Manan between September 2013 and July 2014.
