Nature research paper: Sensory specializations drive octopus and squid behaviour
, Octopuses explore their home tank, moving throughout recordings while squid are stationary and often buried. n = 8-9 trials., Octopuses move toward their prey for capture while squid wait for prey to approach and then strike. n = 4 trials, p < 0.0001 for octopus versus squid movement, two-tailed Student’s t-test., Octopuses spread their arms in relatively dark conditions and contract in the light. n = 10 trials, p < 0.0001 for octopus versus squid movement, two-tailed Student’s t-test.
, Squid use ambush predation to hide and strike shrimp in light or relatively dark conditions with a similar success rate but require that prey are at a much closer distance in the dark. These results suggest squid primarily use vision to strike prey. p < 0.0001 for strike distance in light versus dark, two-tailed Student’s t-test. n = 18–24 trials. Data represented as mean ± SEM.
