Octopuses and squids can also move by using a form of jet propulsion. Water is drawn into the mantle cavity and then forced out through a tube, propelling the cephalopods backwards from danger. In addition, squids and octopuses produce a dark-colored ink when the are frightened. As this ink is released into the water, it helps to hide the mollusks/squids/octopuses and confuse its predators
they move quickly by using their siphon for jet propulsion
By opening and closing their mouths creating a fast & easy way to get away from predators.
Ink their predator then swim away
A squid squirts out a black cloud of dust to get a chance to get away from predators!
yes, they can here predators from far away
Well, the octopus had ink glands like the squid, and if it had fins then not only would it look ridiculous, they couldn't get away from predators. Also, on a octopuses tentacles, there are suction cups. They can't get them on fins, and they work as hands. I think octopuses and tenctacles get along, not fins. Don't you?
A cheetah uses it's great speed to run away quickly from its predators.
To get away from predators quickly.
The foot of the squid is it's tentacles, it enables the squid to move very very very very very very very fast. The foot is also the mantle of the squid (the mantle is a thick layer of tissues {muscle} all mollusks use to protect their guts). In this case the squid uses it's mantle to run away from predators (swim away).
No octopuses don't have enemies because of their ink that they use to block away enemies
by spewing out a dark blackish or brownish ink to make it tough fro their predators to see them swim away.
They have strong legs so they can quickly get away from predators.
they flash their photophores which attract small fish
Dragonflies are agile and able to fly quickly when they are trying to escape predators. They are also able to hide from enemies.
