How specimens are preserved
1 A salvaging officer bags the animal to contain the rotting smell.
2 It is put in an icebox to slow decomposition.
3 The animal is weighed and measured at the office because it might shrink or stretch over time.
4 It is then left in a freezer for at least two weeks to kill pathogens and parasites before any research is done.
5 An autopsy may be conducted to deduce the cause of death.
6 Mammals are typically dry preserved - any part that decomposes is removed. Small animals like bats are preserved whole in alcohol.
7 These are kept in the Lee Kong Chian Natural History Museum, which has some 500,000 specimens. The new museum is scheduled to open next year.
