Interesting how the male changes his color back and forth during the ritual. The Encyclopedia of Life says that the gestation period is 30 to 90 days, and they may have 100 to 1000 offspring.

I know this kind of video makes me hungry for Anchovies and Sunflower seeds. Consider buying at the link below:
