Threespine stickleback pretending to be barracuda.
These guys were commisioned by fellow Flickerite Frenquency to commemorate the end of his PhD studies of this fish species. He studied the evolutionary loss of pelvic spines and was able to switch the relevant genes back on, producing fish with one or both perlvic spines. The thesis title was “The Genomic Basis of Parallel Evolution in Three-spined Sticklebacks”.
