Gene based phylogenetic studies indicate that annelids and mollusks share a recent common ancestor
Mollusks and segmented worms have a one-way digestive system, a separate mouth and anus, and their larvae are very similar. This is the best evidence that they have a common ancestor.
Yes these two share common ancestors.
share similar body plans and patterns of development
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.
This would include the ultrastructure of the cuticle. These creatures share this and many other features with the other annelids.
They all have complex ganglia to control breathing, movement, and digestion.
Squids share two traits with other mollusks: a soft body typically covered by a mantle and a foot modified into tentacles. Additionally, both squids and other mollusks possess a radula, a feeding organ used for scraping food.
All mollusks possess a soft body covered by a hard shell, a muscular foot for movement, and a mantle that secretes the shell. These characteristics distinguish mollusks from other phyla in the animal kingdom.
