Molluscs are invertebrates. They are such a diverse group of animals that it is difficult to generalise about the characteristics. They all have a mantle used for breathing. Their nervous system has a range of development with the most developed in the giant squid. Slugs, oysters, clams, snails are all molluscs. Most have a rasping tongue, most have a muscular foot, most have a type of "kidney" although it does not have the shape of a mammalian kidney.
The type of body cavity shared by all mollusks is pseudocoelom is a false statement. The correct answer is coelom.
they are all in the same category
No mollusks have backbones. They are all invertebrates, meaning they have no vertebral column (backbone).
A zoologist or aquatic biologist might study mollusks. Malacology is the study of mollusks in zoology.
A scientist who studies mollusks is called a teuthologist.
They both have a true coelom and bilateral symmetry.
No, mollusks have a true coelom instead of a pseudocoelom. The coelom is a part of mollusks and annelids that is a cavity within the mesoderm that is filled with fluid.
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.
they have no backbone this is true to all invertebrates
false
True
nope, definitely not
No. Oysters are mollusks, which have shells rather than bones.
No. Squids and octopi are a class of mollusks called Cephalopods, and as with all mollusks, cephalopods are invertebrates.
ok first of all you mean how can mollusks be harmful and think of invasive species
true
bilateral symmetry
