What characteristic distinguishes arthropods and mollusks?
Mollusks compose of the large phylum of invertebrate animals known as the Mollusca. Mollusks have a mantle, mollusks invertebrate. Arthropods have jointed appendages, arthropods have segmented bodies
A mollusk usually weighs just a few ounces, but more when they are stuffed and ready to be eaten!
What is the function of the visceral mass in mollusks?
Visceral mass of mollusks contain all organs but head foot and gills . Thus vascular , excretory reproductive , part of nervous and digestive functions function are performed by visceral mass .
Most shellfish should not be reheated, as the threat of botulism is high for them.
What are stomach footed mollusk called?
A stomach-footed mollusk has a shell to protect its self, tentacles to smell, mouth to eat, foot on bottom of stomach to move, and a head with two eyes on the ends.(ex. snails, slugs, and conchs)
How do mollusks receive nutrition?
Depends on the type of mollusk.
Clams and oysters and scallops generally filter nutrients such as plankton out of the water. Some giant clams also have symbiotic algae growing in their flesh (zoothanthellae) that also contribute to their nutrition.
Some molluscs are fierce predators as well- octopi, squid, cuttlefish, conch, cone shells, and others- they will eat pretty much whatever they can catch. (And several are actually venomous! A sting from a cone-shell can make you very very sick indeed, or even be fatal!)
(Biology teacher/Professional Naturalist)
Molluscs eat all kinds of things. The cephalopods (octopi, squids, and their allies) are predators of fish and other marine life. Most bivalves are pretty much herbivorous, feeding primarily on phytoplankton, though some are predators. The gastropods are also mixed, with some herbivorous, such as abalones, and some carnivorous predators, such as moon snails, oyster drills, and cone shells. Incidentally, some cone shells (Family Conidae) are poisonous enough to kill people! They also eat snails.
Cougars, also known as pumas, mountain lions and panthers, are territorial and therefore hunt and travel alone....
Cougars do not hunt in packs. They are the most widely distributed land mammals in the Western Hemisphere other than humans, but they prefer to hunt their prey alone, which consists of meat.
The cougar is a carnevorous and is capable of killing prey up to the size of elk, however white-tailed deer, mule deer, marsh deer, peccary, and guanaco are the most common items of their diet.
What are the characteristics of the three groups of mollusks?
The presence of he shell, the type of shell, the type of foot, and the type of nervous system
Why are fossils of mollusks more abundant than those of the worm phyla?
Fossils of mollusks are more abundant than those of worm phyla primarily due to the hard, durable shells that many mollusks possess, which are more likely to be preserved in the fossil record. In contrast, most worms have soft bodies that decompose rapidly after death, leaving little to no trace. Additionally, mollusks have diverse habitats and a long evolutionary history, increasing their chances of fossilization. The combination of these factors contributes to the greater abundance of mollusk fossils compared to those of worms.
Why are snails and insects similar?
snails and mosquitos can both play host to very nasty viral or parasitic passengers. snails can carry a parasite the causes schistosomiasis and different mosquitos can carry anything from dengue fever to yellow fever to malaria to west nile virus to philariasis.
schistosomiasis is very treatable if caught before late stages where as malaria, west nile, or dengue can cuase death very rapidly, some cases even 24 hours.
What is the function of the ink sac in mollusks?
Protection from enemies. Squids spray their ink to create a cloud that distracts a predator long enough that allows the them to escape
What is mollusk with tentacles?
Mollusks with tentacles are cephalopods. Cephalopod in Latin means, "Head-foot".
There are about 3,300 various species of cephalopod, including octopuses, squids, cuttle-fish, and nautiluses.
Sizes range from the tiny Wolfi octopus, about the size of 1 1/2 sugar cubes, to the architeuthis Colossal Squid, larger than a giant squid, whose full-grown length is up to 46 feet, or perhaps even longer. The giant squid runs from about "only" 33 feet to 42 feet, full-grown.
Which are the simplest animals to have body symmetry?
They are butterflies,moths,ants,bees,bears,bunnies,dogs,cats,rats,and road runners.
(Sorry,but that's all I could think of)
No. A Nudibranch is a mollusk, which is an invertebrate, related to marine snails that looks like a slug.
Invertebrate means lacking vertebrae (backbone).
All mammals are vertebrates, thus they have a backbone.
