So, coconut crabs can supposedly grow up to 1 meter long

Coconut crabs are the largest land-living arthropod in the world, with a weight of up to 4.1 kg (9.0 lb). It can grow to up to 1 m (3 ft 3 in) in length from leg to leg. Found on islands across the Indian Ocean and parts of the Pacific Ocean as far east as the Gambier Islands, mirroring the distribution of the coconut palm; it has been extirpated from most areas with a significant human population, including mainland Australia and Madagascar. Definitely not something I would like to find in the garden!
