A large rare carnivorous New Zealand snail has been filmed laying an egg from its neck for the first time, in a delightfully icky stroke of luck.

The department of conservation, which has been managing a captive population of Powelliphanta augusta, or the Mount Augustus snail, for almost two decades, was undertaking a routine weight check when a small, white egg started emerging from a snail's neck.
