As has been summed up, the advantages and
disadvantages of collecting live versus dead material
depends on your goals. For some types of study, live
material is necessary. Anatomical studies obviously
require live animals, as do molecular studies. On the other
hand, dead shells generally give a pretty good idea of the
local fauna. Folks have noted the risk of some extraneous
shell turning up, and there is some degree of transport
between habitats as well, but the common dead shells
almost certainly give a good picture of the local live fauna.
