That is the marine iguana. In 1835, Darwin described this lizard as a "very disgusting and sluggish" demon of the dark. And rightly so, as its jet-black skin, blunt snout, and the substance it expels from its nostrils are traits quite different from those of ordinary lizards. Why on earth do marine iguanas look like this? And how did they end up settling in the Galapagos? Discover the secrets of marine iguanas through this video. #MarineIguana #Galapagos #Evolution ============================================= [References] Darwin, C. (1839).
