The vampire squid (Vampyroteuthis infernalis) is a fascinating deep-sea creature known, among other things, for its unique ability to turn itself 'inside out'.
This unusual behaviour is a survival tactic used to protect itself from predators. When threatened, the cephalopod inverts its body, pulling its head into its mantle and covering itself with a film of bioluminescent mucous.
This inside-out manoeuvre exposes its spiny arms and makes it appear more threatening than it really is. Additionally, the vampire squid's dark, cloak-like webbing and reddish hues help it blend into its shadowy ocean environment.
