Mollusks

Yes. They are a danger especially to the fish population since many fish species need sandy or muddy bottom soil to lay their eggs. The zebra mussel covering the lake bottom prevents nesting to these species of fish. The mussels have proliferated so much that they are actually clearing up the murkiness of the lakes.

Some adaptations of mollusks include an operculum that most univalves have for protection, the radula of the moon snail that is used to drill through other shells to get their food, and the jet propulsion movement and ink sac of cephalopods to escape predators.

Zebra mussels compete for plankton with other filter feeders, but that is not really why they are considered to be a problem. They tend to grow in great abundance where there is a water current that brings them their food faster, and such currents occur at the intake pipes that are put into the Great Lakes to get water, and the pipes then get clogged. So it is more of a problem with human engineering, than a problem affecting the food chain.

New Answer:

they will compete with netive shelfish and clams and hurt their populations

very good question. im sad that nobody has an answer.

they would have less protection.

Some mollusks have a foot like a snail and can move very slowly. Others only move around as larvae and once they get big enough to grow shells, they stay put. Cuttlefish, squid and octopods are part of this family but they can swim.

No. Calimari is Squid. Try the appetizers at Olive Garden and eat the Calimari its great!

Conch poisoning affects people who consume raw conch, which has been contaminated by large numbers of bacteria. Hope this helps!!!:D

mollusc's do not hear rather their sense of touch is high for them to detect approaching objects

An animal that eats, only other dead organisms is called a scavenger. An example might be crows or vultures.

some give live birth (Viviparus malleatus) , and some lay eggs(Octopus vulgaris).

Periwinkles tast like oysters when dipped in butter.

No, they are different types of animal.

Yes: clams, oysters, mussels, etc.

Depends on the mollusk. Most use sexual but some snails are hermaphrodites and can perform asexual reproduction.

Vieria (in the Castillian Spanish)

In Mexico they call it Callos de Hacha.

The hardest seashell to find might be the cowrie shell because they tend to be very well camouflaged. The outer surface of the shell is extremely hard and the walls are thick as well. The hardness of the seashell is related to its size and the thickness of its walls.

Most arthropods utilize legs or fins to move, but some of the following animals have unusual movement systems; some clams can jump, squid use biological jet engines to shoot water out of their bodies and propel themselves, extinct anomalocaris used flat rows of spikes made of chitin (typical arthropod exoskeleton material) to propel themselves by doing a wave motion that slowly, but effectively, through the water by pushing water behind themselves. But sometimes sacrifices energy to accelerate.

ONLY plants are producer

ONLY fungi and bacteria are decomposers

ALL other living things are consumers

You need to ask yourself - is a Mollusk as plant or a fungus or bacteria, if not then Mollusks must be consumers.

Yes, they are located in Lake Michigan and can be seen washed up on the beach.

Barnacles don't move once they settle down as a tiny larvae on their chosen surface. Limpets can move around on their broad foot. Some limpets have holes at the top of the hard shell, others do not. The hole is not closed by plates.

Mussels filter mud and extract tiny food particles and "spit" out the rest
