[Zbrafish] Variable number of zebrafisch somites?
(by jan.gebauer from uni-koeln.de)

I found the following paragraph in Kimmel et al. (1995) Dev. Dyn. 203
[Somite formation in zebrafish]
The last somites of the series form more slowly than the others (not shown
in the idealized curve of Fig. 181), and the total number that eventually
forms is variable,
from 30 to 34 pairs.
Does anyone know what they mean with "variable"?
Variable between strains? ... or individuals of single strain?
How is it regulated? ...genetically? or by the environment? or just by
I actually never counted the somites of our adults... Probably I should,
but perhaps someone knows the answer.
Thanks for any hints...
