A colony of fur seals which usually live at the Galapagos Islands in the Pacific Ocean have swum 1,500km away because of global warming.
The group of animals is now living in Northern Peru, according to the organisation which tracks them.
Average water temperatures in Peru have risen over the past 10 years and are now closer to the Galapagos.
Now experts say that more fur seals and other species from the Galapagos could start arriving too.
The Galapagos Islands are home to many unique animals, and are famous for helping Charles Darwin come up with his theory of evolution.
There are worries though that climate change could have a devastating effect on the area.
The research into fur seals was done by The Organisation for Research and Conservation of Aquatic Animals.
