"Jumping spiders (Portia spp.) plan routes towards their prey; and hermit crabs (Pagurus berhnardus) show evidence of motivational trade-offs during shell choice. Furthermore, if their brains are implanted with electrodes, garden snails (Helix aspersa) will learn to displace a lever, an action new to their behavioural repertoire, to stimulate those neural regions involved in sexual behaviour. None of these represent concrete evidence of conscious emotion, but they at least suggest that if cephalopods are to now be protected across Europe, then arachnids, decapod crustaceans and gastropods should be too."
