Many Galapagos marine animals die or cannot reproduce successfully due to the lack of food, the researchers wrote. El Niño is caused by a shift in the distribution of warm water in the Pacific Ocean around the equator. From that species emerged marine iguanas, which spread to nearly all the islands of the archipelago. Each island hosts marine iguanas of unique size, shape and colour, similar to Darwin's famed hummingbirds. However, during El Nino years, their usual food source suffers as warm waters prevent the algae from flourishing as usual.
