Marine Iguanas

On the Galapagos Islands, marine iguanas have developed new behaviors to make the most of the rich meadows of algae offshore. They can hold their breath up to an hour while feeding on the algae. After the excursion, a gland in the marine iguana’s nose filters out excess salt that it unavoidably ingests while foraging in the ocean. Then all the iguana has to do is sneeze.
