Cool Cephalopod Vids
- Octopus bottom locomotion
- Octopus slithering into a bottle- a
demonstration of flexibility
- Octopus "goose bumps" and
sucker structure
- Octopus escape responses
- Octopus escape responses: 1) be a
chunk of sea weed or sponge, 2) Be big!, 3) Use camouflage to hide on a rock, 4) surprise
the predator by blanching, 5) Inking, and 6) being really weird looking with big,
dangerous eyes
- Squid light signaling and prey-capture
- Squid threat display- The squid at
the top (with the dark waves) owns the territory. The reddish one at the bottom of the
screen moves off. Both are males. At the end of the sequence another squid demonstrates
some of the possible color changes.
- Squid threat display- Same as
above, but a shorter loop.
- Squid color displays- More color
display, along with "goose bumps". The sequence is followed by a squid capturing
a glass shrimp. The squid can easily see the glass shrimp because the eye polarizes the
light.
- Squid camouflage- Note how the
spots on the back change to match the background. The end of the sequence shows how
well-hidden he would be to an animal with monochromatic vision.
- Squid vision- How the polarizing
eye sees a squid predator (a barracuda)
- Various deep-sea cephalopods- 1)A
red squid with long tentacles, 2) a pair of octopuses may be a male and female, 3) a
threat display by an octopus with webbing running the full length of the arms. First he
gets big, then he inflates and turns into a pumpkin.
