Table 3 
Species specific mean differences in length following preservation within 1-millimeter length intervals. The number of specimens 
is indicated by n. Subscripts in the fourth and seventh columns refer to the species for which information was available within 
each length interval (t= 1, . . . , n). The standard deviation of the species specific difference in length (SD) is also provided. A 
positive difference in length indicates expansion whereas a negative value indicates shrinkage. The last three columns present 
the analytical results for overall changes in length following preservation, differences among species, and homogeneity of vari- 
ance between fresh and preserved specimens within each length interval.
