Cuttlefish mimic hermit crabs
Cuttlefish have been filmed apparently imitating hermit crabs.
Researchers from Japan first spotted the odd behaviour in Pharaoh cuttlefish,
Sepia pharaonis, while feeding them in the lab at the University of the Ryukyus.
The cuttlefish raise their front arms and wave them about, while bending those behind to make them look as though they are jointed, like legs of crabs.
They were filmed impersonating hermits when prey was present. As hermit crabs aren’t predators, researchers think it could be a method of lulling potential prey into a false sense of security before striking. But the mimicry could also be useful in defence, by fooling predators into thinking the soft-bodied cuttlefish are covered in a hard shell.
