All mollusks share several key features, including a soft-bodied structure typically divided into three main parts: the foot, the visceral mass, and the mantle. They possess a radula, a specialized feeding organ used for scraping or cutting food, and most have a hard shell made of calcium carbonate, though some species are shell-less. Mollusks also exhibit bilateral symmetry and have a well-developed nervous system, with varying degrees of complexity across different classes. Additionally, they have a coelom, which is a fluid-filled body cavity that houses their internal organs.

their weirdness
lm.,
they are slick slop and slimy
Some common features of squids and other mollusks include a soft body with a muscular foot, a mantle that secretes a shell (if present), and a radula for feeding. They also have a visceral mass containing organs such as the heart, digestive system, and reproductive organs. Additionally, mollusks possess a mantle cavity that houses the gills and functions in respiration. However, not all mollusks have all these features, as there is a wide diversity within the phylum.
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.
yes
Vertebral column is not present in all mollusks.
No. Oysters are mollusks, which have shells rather than bones.
ok first of all you mean how can mollusks be harmful and think of invasive species
