For the first time in human history, technology is allowing us to explore the darkness and crushing pressure of the deep seas- to reveal the strange ecologies that exist here. The deep-sea humpback anglerfish (Melanocetus johnsonii) is the ugliest fish I have ever seen. It is the size of a tennis ball and it loves to eat. The females are much larger than the males. Millions of light-producing bacteria exist in the lure on its nose. This model was made by Mike Leveille from Ottawa, Canada.
