It’s possible that at certain times of the year great white sharks could be near to the Galapagos Islands.

This scuba diving lizard can stay underwater for long periods, where it was originally thought it was holding its breathe. The river anole can remain submerged for at least 16 minutes. It does so by blowing out air into a bubble and then re-inhales this air whilst underwater.
