Mollusks

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.

Seashells are created by snails. When snails are first born, their skins are soft, then they harden and calcify and detach from the rest of the body. They continuously grow around their own shells more and more, which is where the spiral comes from. When the snails die, the soft portion decays and the hard shell remains. More Some shells are also those of clams, scallops, or oysters. Depending on the location, any of these might be more numerous than the shells of snails. In any case, the process of formation is similar: A soft-bodied mollusk secretes calcium carbonate which accumulates as the shell as the animal grows, then the empty shell remains when the animal dies.

they have no backbone this is true to all invertebrates

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.

A zebra mussel is a small freshwater mollusc similar to a clam. They are native to several freshwater lakes in southeastern Russia. In recent centuries, they have spread through man-made canals to the Caspian Sea and many lakes and rivers throughout Europe. In the late 20th century, they spread to North America, first appearing in the Great Lakes in 1988. They probably crossed the Atlantic Ocean in ballast tanks of ships that had sailed from freshwater lakes in Europe to the Great Lakes.

Zebra mussels are considered an invasive pest in North America and in some European countries to which they have spread. They breed prolifically, such that even in their native environment, they live in very high densities. In environments to which they have recently migrated, they have a negative impact on the ecosystem by outcompeting native mussels and other filter-feeders. They are a nuisance to humans because huge numbers of them attach themselves to any available surface, including the insides of pipes used for power plants, canal locks, and municipal water supplies.

The anus of an octopus is behind its brain.

It lives in the tropical oceans.

The bodies is an invertebrate.

the answer is echinoderms are closer related to humans because they have a spine while mollusks do not

Aquatic Nuisance Species

they could if they were hungry enough, and if cats ran around in the mountains! they also would like anything that has meat, they are carnivores!! cats dont usually eat cats but if they did they would leave remains as in guts and other stuff.
Yes, Bobcats can be extremely viscous. They do whatever they feel necessary to live. If the bobcat does not feel threatened by your cat, it may just eat it's food, and eventually wonder off.... If it finds food though, it WILL be back. Try to capture the bobcat(in a live trap) and release it elsewhere so that your cat/cats are not threatened on their own property.

it is called a bivalve

All Molluscs possess a body plan of a muscular foot, a visceral mass, and a mantle. Mollusks are also soft-bodied animals coming from the Latin root of the name molluscus meaning soft.

No, they don't get pregnant hello! only mammals do

WELLL, cephalopods, a type of mollusks, have a mantle and feet no, more like arms and tentacles. the word 'cephalopod' means 'head-foot' meaning their heads are close to their feet[-like things]. their mantle is not the same as their head; it is on top of their head, yet larger than it. Hope that helps! 0n0

U

most animilia in phylum mollusca have an open ciculatory system along with a false ceolom

Head/Foot - Has sense organs and is used for mobility.

Mantle - Covers the body mass and can secrete a shell in some species.

Body - Contains the main organs. Located above the head/foot.

oysters

There are many which might have oval or close to oval shells, but one that comes to mind quickly is the cowry, some of which are nearly perfectly olive shaped (Class Gastropoda, Family Cypraeidae).

fr

no its a sea creature usually containing a hard exoskeleton

Clams donÕt basically grow; they actually shed their shells through a process called molting. After a few days, a new shell will grow on the shell edge of a clam.
