Baby Cuban crocodiles rest inside their enclosure at the Skansen zoo and aquarium in Stockholm, Wednesday April 15, 2015. Zoo director Jonas Wahlstrom says they were originally given as a gift from Fidel Castro to a Soviet cosmonaut four decades ago. The zoo is sending 10 of the pair’s hatchlings to Cuba for introduction into the wild. The Cuban crocodile is considered critically endangered. (AP Photo/David Keyton)
