Squid, octopus, nautilus, and cuttlefish are among the cephalopods, a category of mollusks that includes squid, octopus, nautilus, and cuttlefish. Their members can be found in any ocean on the planet. Their three hearts pump blue blood and propel themselves forward using jet propulsion. Since the foot is close to the head, the word cephalopod means head foot. The octopus and squid’s feet have turned into a funnel. This funnel can be used to get around the animals. They need to get the water out of their bodies. The cephalopods can move rapidly thanks to jet propulsion. The rest of their bodies are bizarre as well many of them have a digestive tract that runs straight through their heads Cephalopods have a lot of surprises in store for you!
