They are masters of disguise, changing color and texture to blend with their surroundings. Octopuses are generally poor swimmers; they prefer crawling along the substrate using their arms or employing slow, rhythmic contractions of their mantle to jet short distances backward.

An octopus lacks any internal skeleton, giving it incredible flexibility to contort its body through any opening wider than its beak. An octopus is a solitary creature, typically found resting on the sea floor among rocks or coral.
Squid, however, have a more rigid structure; the internal pen provides a point of attachment for powerful muscles, aiding in jet propulsion. Octopuses are predominantly benthic, living on the seafloor in diverse environments ranging from shallow tide pools to the dark depths of the abyssal plain.
