Decoy eggs made by a 3D-printer and fitted with satellite tags have been placed in sea turtle nests on beaches in Costa Rica to track the illegal trade of their eggs.

A quarter of the fake eggs put among 101 turtle nests on four beaches in Costa Rica were stolen, with some eggs successfully tracked as they moved from thief to trafficker to consumer.
