The first nuclear bomb exploded at Trinity, Alamogordo, NM on July 16, 1945. This is a "Fat Man" bomb design identical to the one dropped on Hiroshima on August 6, 1945.

An elaborate design to attract females. The geometric precision and variation in design between individual male puffer fish is amazing.

Puffer fish have interesting genomic organizations in that they're a convenient molecular starting point in tracking the evolution of DNA regulatory sequences in vertebrates more evolved than puffer fish. Regulatory sequences in higher organisms are dispersed and not in proximal contact with the gene(s) they regulate.
