Why do we want to make specimens last forever?

Because of their value!
Because they are unique--and a limited resource!
Because of the costs involved with acquiring a specimen!

Costs of time:

 
  • Time for staff person to find the right kind or species;
  • Time for staff at other institutions to locate one for us and send it;
  • Time for a staff member to prepare the specimen for research;
  • Time required to find someone else, such as a taxidermist, to mount the specimen in a life like pose;M
3.

Costs of materials:

 
  • Materials to collect the specimens;
  • Materials to prepare or mount the specimen;
