a class of animals in the phylum Mollusca. These animals are invertebrates with two basic body parts, a head and a mantle. A cephalopod has a well-developed brain, and a circulatory system with three hearts, veins, and arteries. Usually cephalopods have ink sacs and no external shell. Not only do they live in the sea and use jet propulsion in order to move, they can usually change skin color and texture.
A class of marine molluscs that include squids, octopuses, cuttlefish, and nautiulus. They all have a circle of prehensile tentacles and a muscular funnel through which they expel water to provide them with a form of jet propulsion.
Any of various mollusks, such as an octopus, squid, or nautilus, having a beaked head, an internal shell in some species, and prehensile tentacles.
Marine mollusks, including squids and octopuses.
mollusc with a greatly reduced shell (compared to other molluscs, for example, the snails) and tentacles (including squids, octopuses, cuttlefish, and nautiloids).
marine mollusk characterized by well-developed head and eyes and sucker-bearing tentacles
a mollusk with an internal shell --like a squid or octopus
an animal like an octopus or a squid, soft and squishy, with tentacles
A member of a group of marine invertebrates that includes octopuses, squids, and their relatives (both modern and extinct), including shell-bearing forms, such as the pearly nautilus. chancel The part of a church in which the main or only altar is found.
the class of marine invertebrates that includes squid, octopus, cuttlefish and others.
a mollusc having a distinct head with prehensile and locomotive organs attached, e.g. octopus, squid and cuttlefish.
mollusc of the class Cephalopoda, which includes squids, cuttlefish, octopi, nautiloids, and ammonoids.
A type of mollusk that includes forms common in the fossil record. Ex: ammonites and squids.
A group of invertebrates, including squids and octopuses, fed on by many marine mammals. Chevron bone- The V-shaped subvertebral arches which inclose the caudal blood vessels in some animals. Form after the os coxae below the caudal vertebrae.
Shelled octopus-like creature. Shells are often conical and show partitions that allowed flotation.
Cephalopod - Any marine mollusk belonging to the class Cephalopoda, characterized by a definite head, with the mouth surrounded by part of the foot that is modified into a lobe with tentacles or arm-like appendages with hooklets or suckers or both. The external shell, if present, as in nautiloids, is univalve and resembles a hollow cone; it may be straight, curved, or coiled and is divided into chambers; the shell is internal in present-day cephalopods such as octopuses, squids, and cuttlefishes and their fossil ancestors, such as the belemnites. Nautiloids and ammonoids are extinct and generally valuable as index fossils. Range: Cambrian to present.
A member of a group of mollusks including cuttlefish, squid, and octopus.
a group of marine molluscs which have a soft body, grasping tentacles and a well developed nervous system. Fossil examples include ammonoids and belemnoids. Living examples include octopus, nautilus and squid.
A mollusk that has a tubular siphon under its head, a group of legs with suckers around the head, highly developed eyes, and a sack of ink that may be ejected for concealment or defense. Octopus, squids and cuttlefish belong to this group.
Cephalopods include squid, octopi, cuttlefish, and chambered nautiluses. They are mollusks with tentacles and move by forcing water through their bodies like a jet.
a member of the group of molluscs that includes octopuses, squid, nautiluses and cuttlefishes. Cephalopods all have many arms and well-developed eyes. Certificate level: Level of competency-based learning (AUS).
Cephalopods (meaning "head foot") are mollusks with tentacles and a large head. These soft-bodied invertebrates include animals like squid, octopuses, cuttlefish, and the ammonites (extinct). They are fast-moving carnivores that catch prey with their tentacles and poison it with a bite from beak-like jaws. They move with by squirting water through a siphon, a type of jet propulsion. Many also squirt ink to help escape predators.
The cephalopods (Greek plural (kephalópoda); "head-foot") are the mollusk class Cephalopoda characterized by bilateral body symmetry, a prominent head, and a modification of the mollusk foot, a muscular hydrostat, into the form of arms or tentacles. Teuthology, a branch of malacology, is the study of cephalopods.
