Cephalopods have a closed circulatory system and the other mollusks have open circulatory systems
Cephalopod's are more complex than any other Mollusks.
Complex=smarter
cephalopods shells are more complex than all the other mollusks
I don,t know do you know what cephalpod can eat pffin?
they have a closed circulatory system
They have a closed circulatory system.
a cephalopod move using jet propulsion
the answer is cephalopods which means head-foot
Cephalopods are a phylum of mollusks that include squids, octopi, the chambered nautilus, and cuttlefish. All cephalopods have tentacles, most are carnivores, and they are all mollusks. All mollusks have a radula, or toothy tongue, a mantle, or thin layer of tissue that covers the organs and makes the shell, and a muscular foot.
Most of Mollusks protect themselves with help of shell . Shell is hard protective covering made up of CaCO3. Cephalopods are not protected by shell .
They are most related to other cephalopods like squid or cuttlefish. They are distantly related to other mollusks such as oysters or slugs.
Most mollusks have a closed circulatory system. However, cephalopods have an open circulatory system.
They may learn certain behaviors, but most behaviors such as eat and moving are inherited.
cephalopods, as they have sensory organs closest to vertebrates.
Some adaptations of mollusks include an operculum that most univalves have for protection, the radula of the moon snail that is used to drill through other shells to get their food, and the jet propulsion movement and ink sac of cephalopods to escape predators. - a jeark
Some, such as octopii, possess a brain, but most mollusks just have concentrations of nerve cells in their body that serve as primitive brains, called ganglia (singular ganglion). To add to the previous answerer, Cephalopods (squids, chambered nautilus, octopi, cuttlefish) have a brain.
Characteristics include:MantleMuscular Foot (in cephalopods this has branched out to form tentacles and arms)Radula - a chainsaw like feeding tongue (secondarily lost in some species such as the bivalves and some cephalopods)Calcium Carbonate Shell (secondarily lost in some cephalopods and some gastropods)Open Circulatory System
