Joeys in Pam Turner’s home, sheltering from the Grampians bushfire in Australia. As fires headed toward her property, the wildlife carer took 20 young kangaroos into her living room. The animals – standing alert due to the noise of the sprinklers – were all hand-reared by her after being orphaned through car accidents, fence hangings and shootings. They were too large to be evacuated, yet too young to fend for themselves

A Desertas Island land snail. The pea-sized snail was believed to have been extinct, but it may have been pulled back from the brink this week after more than 1,300 bred in the UK and France were released back on to the Portuguese island. Chester Zoo spearheaded the breeding project. Dr Gerardo Garcia, the zoo’s head of ectotherms, said: “They’d never been in human care before and we had to start from a blank piece of paper and try to figure out what makes them tick: how to care for them, how to create an environment in which they could flourish, and how to encourage them to breed”
