The video shows Fiddler crabs hurrying for cover across the mudflat, which resembles a migration. This usually takes place when a boat comes near to the place where they are foraging or sunbathing. A well known evolutionary treat, the sexually dimorphic claws of the Fiddler crabs are on full display in the recording. The males’ major claw is much larger than the minor claw, while in case of the females, both claws are the same size.
Although it is not as grandiose in terms of grounds covered as the Caribou migration, the African elephant migration, and the wildebeest migration, to mention the most notable ones, but it is breath taking in numbers when the Fiddler crabs move across the mudflats of the Meadowlands.
