Galapogos Iguanas reduce body size during drought years.

<excerpt>
In two studies of Galapagos marine iguanas, one spanning 18 years and
the other occupying eight years, scientists found that the herbivorous
reptiles shrank as much as 2.7 inches, or 20 percent of their body
length.

The researchers hypothesize that bone absorption accounts for much of
the shrinkage.
