Sharks is less ebullient in feeling, probably because the subject is more alarmingly awesome. Gibbons again uses clear blues and greens and soft grays, but her palette is modified here with browns, startling touches of pink, orange, and yellow, and a sharp reduction of the frothy white of the earlier book. A few illustrations show sharks in somewhat contorted positions, giving odd angles to caudal appendages. The information is specific and generally accurate, although sources consulted referred to months rather than the ``few weeks'' Gibbons gives sharks' ``thorny cased eggs'' to develop and hatch. The data is often quite complex, and may be beyond a portion of the audience to which this format will have the most appeal.. --This text refers to the School & Library Binding edition.
