Definitions

1. Octopuses are classified in the phylum Mollusca, class Cephalopoda, order Octopoda, family Octopodidae, genus Octopus.
2. Octopuses are highly intelligent, probably more intelligent than any other order of invertebrates.
3. Octopuses are characterized by their eight arms (not tentacles), usually bearing suction cups. (Web site)
4. Octopuses are cephalopod mollusks characterized by having eight arms, no tentacles, and the internal shell lost or considerably reduced. (Web site)
5. Octopuses are masters of camouflage that can change their shape, colour and texture to perfectly blend into their environment. (Web site)

Course

Nautiluses

Group

Related

1. The Vampire Squid, however, is more closely related to the octopuses than to any of the squid. (Web site)

Vulnerable

1. This is a dangerous time for the larval octopuses; as they become part of the plankton cloud they are vulnerable to many plankton eaters.

Light

1. Octopuses, like other cephalopods, can distinguish the polarization of light.

Six Months

1. Octopuses have a relatively short life span, and some species live for as little as six months.

Humans

1. Octopuses, naked and vulnerable, took to dens, as early humans took to caves. (Web site)

Ability

1. Surprisingly—given their ability to change color—all octopuses[ 11] and most cephalopods[ 12] are color blind. (Web site)
2. Other scientists had already tested the ability of octopuses to solve mazes, learn cues, and remember solutions. (Web site)

Mantle

1. Octopuses can use muscles in the skin to change the texture of their mantle in order to achieve a greater camouflage.

Learning

Internal Shell

1. The octopuses in the less familiar Cirrina suborder have two fins and an internal shell, generally lessening their ability to squeeze into small spaces.

Lack

1. Nautiluses are enclosed in shells, squids have a shell that is reduced and internal, while octopuses lack a shell. (Web site)
2. Octopuses often escape even from supposedly secure tanks, due to their intelligence, problem solving skills, mobility and lack of rigid structure. (Web site)

Similar Manner

1. When under attack, some octopuses can detach their own limbs, in a similar manner to the way skinks and other lizards detach their tails. (Web site)

Marine Animals

1. Cuttlefish are marine animals of the order Sepiida belonging to the Cephalopoda class (which also includes squid, octopuses, and nautiluses).

Camouflage
