767 Questions
What is the scientific name for zebra mussels?
The scientific name for zebra mussels is Dreissena polymorpha.
What is the genus of mollusks?
Mollusks don't have an genus, they are a separate phylum on their own. Only if you are refering to a specific mollusc, then a genus can be specified.
No, a conch is a mollusk (I think) and why is your question under Lord of the Flies
No, a conch is not a vertebrate. Conchs are marine mollusks with a spiral shell, belonging to the phylum Mollusca. Vertebrates, on the other hand, are animals with a backbone.
Is it safe to eat conch salad in the first trimester?
It is recommended to avoid eating raw or undercooked seafood, including conch, during pregnancy due to the risk of foodborne illnesses. It is best to opt for thoroughly cooked seafood to reduce the risk of any potential harm to both you and your baby.
The conch mentioned in Lord of the Flies is a conch shell, so it wouldn't be slimy at all. The creature which originally lived inside the shell was a type of mollusc (a sea snail) and it would have been slimy.
No - sea urchins are part of the echinoderm phylum, with sand dollars, starfish and sea cucumbers.
What physical structure is found in all mollusks?
It is actually only three common structures since not all mollusks have shells. Here it is:
Head- structure that contains the mouth, brain and sensory organs
Foot- muscular structure that extends from the body and is used for movement
Mantle- fleshy tissue that covers and protects the internal organs. It also secretes the shell for most mollusks
:) B) =3 -_-
the positive way is they are food for human and the negative way is land slugs and snails damage plants
Do mollusks have a water vascular system?
ya, yes, si.... they do have a water vascular system. They use it for moving and getting food.
:D hope this helped! :D
Mollusca is a phylum of animals, just as Chordata (our phylum) is. It's a group with wonderful variety, including animals that don't even have brains (clams and oysters), through those with very simple ones (snails and slugs) to creatures some scientists suspect are as smart as dogs or monkeys (cuttlefish and squid).
It is used by the squid during mating season to release both mating calls and massive amounts of sperm into the water. Anyone who says they are used for breathing is a liar.
Why do mollusks leave their shells?
No species of snail is able to 'leave' its shell. The shell is connected to the snail like a permanent tooth. If it were to leave its shell it would die. so unfortunately the snail probably died, or was eaten by a predator.
What do freshwater mussels eat? • Fish, turtles, leaves? No - freshwater mussels eat microscopic plants and animals called plankton • They also eat bacteria and detritus (dead plant and animal pieces) suspended in the water.
How do freshwater mussels eat? • Freshwater mussels do not hunt or search for their food; they wait for it to come to them • Freshwater mussels filter feed by sucking water in through a siphon (kind of like a little hose) • Water passes over gills where food particles get filtered out and carried by little hairs called cilia to the mouth
How do mollusks move scientifically?
Mollusks in the classes gastropod (snails, slugs, nudibranchs) and bivalves (clam, mussels) move with a muscular foot. In the class of cephalopods, the foot has become 8 tentacles and no longer is used for movement. In this case, they use jet propulsion and water propels them away from predators or towards prey.
How do snails make there shell?
Snails are born with their shell. As the snail grows, so does its shell -- in a spiral shape. New shell is added at the opening of the shell by the mantle. In the center of the spiral is the part of the shell that the snail began life with.
The shell is made from several layers. The thin outer layer is made from an organic substance known as conchiolin. The thicker layer underneath is formed from three layers of crystalline calcium carbonate, similar to the chicken egg of which you may be more familiar. The color of the shell depends on the types of food the snail is eating and also the type of snail.
The red abalone can be 8 to 12 inches (31 cm) in size.
What problems does the sea urchin have in its habitat?
Sea Urchins role in the ecosystem is to provide a canopy habitat for larval, juvinile and some adult fish and invertebrates to hide and grow under until they are large enough to emerge safely. Sea Urchins are algae and detritis eaters which keep a balance in the benthic habitat by grazing on which if left can cause spikes in bacteria levels or in the case of coral reefs can smother coral. They move around and clean up the bottom. Lastly Sea Urchins are a food source for humans, fish and other animals. Sea Urchins can very easily overpopulate and if they do can wreak havoc in large areas in the ecosystem, particularly inside of Marine Reserves. Little is known about this phenomena of Sea Urchin Barrens other than that they can last for decades until a disease hits and there is a mass die off. In California, habitat restoration efforts are underway to eradicate these Sea Urchin Barrens or Urchin Dominated Areas by Santa Monica Baykeeper and the Orange County Baykeeper. It seems ironic that they would advocate for Marine Reserves in the MLPA process which in effect causes Sea Urchin Barrens that contradicts their efforts to restore the habitat that they have or about to destroy. Look on u tube for the Baykeepers videos and also for other sea urchin barrens videos.
Why do mollusk lay so many eggs?
Because in the wild 99.9% of them (or so) get eaten. So in numbers there is strength....and survival. IT IS SO LAME!!!!
