Deep below the ocean surface, light is in short supply. But dive photographer Steven Kovacs specializes in capturing the ethereal creatures that live in this darkness. Many of his subjects are larval fish, whose forms defy our hydrodynamic expectations. Why would young (presumably less energetic) fish have so many long, drag-inducing appendages? Clearly there’s more to life under the sea than streamlining alone!
Perhaps our instincts are wrong and these shapes are not as detrimental as they look at first glance. Flexibility can make a drastic difference in hydrodynamics, after all. And some of these species are preparing themselves for a life not spent entirely underwater, anyway. (Image credit: S. Kovacs; via Colossal)
