There's more than just one creature lurking in this black lagoon. Here, in this bizarre netherworld between river and ocean, evolution has created a variety of freakish assassins, many of whom strike in the blink of an eye. Witness the fast-paced action in slow motion as our high-speed cameras capture sharp-shooting archerfish, African fish eagles, mantis shrimp, and other killers at work. Cutting-edge CGI details show just how they use their alien jaws, spear-like arms, and color-changing skin as weapons of underwater war.
