lucky 7 slot machine Owing to rat predation, it’s thought that no tortoises have hatched out on Pinzón in 150 years or more. But baby giant tortoises are notoriously difficult to spot, often concealed beneath loose lumps of lava so there were probably very many more. “I suspect there were 100 to 300,” says James Gibbs, who has written a lovely piece for the Galapagos Conservancy blog about his recent survey of Pinzón.

Gibbs and others on the survey looked very hard for signs of live rats, but found none. “As a biologist I have had a time comprehending that every rat was killed,” he says. “But they seem to have done it.”
The challenge now, in an archipelago with 30,000 residents and 200,000 visitors every year, will be to prevent rats from finding their way back to Pinzón.
