Radula
radula. The radula is a tongue-like organ equipped with rows of small, chitinous teeth that are used to scrape or rasp food particles off surfaces. It is primarily found in gastropods such as snails and slugs, but is also present in other mollusk groups like chitons and some cephalopods.
they can be any color except for white, gray or green.
Everything is available except feeding the animals.
Astronomers have difficulty looking at distant stars because while we have highly specialized telescopes, they are in constant contention with various other celestial bodies. In addition to this, the light of distant stars takes hundreds of thousands of years to reach us, making it impossible to get a current look at a distant star.
A is like a plain except that it is cut by a steep canyon?
Metals:All metals are hard except sodiumAll metals have a high density except sodiumAll metals are solid at room temperature except mercuryNon-metals: All non-metals are insulators to electricity except graphiteAll non-metals are brittle except diamondi dont have an answer for 3 sorry! :(
The radula (or some form of the radula) is found in all classes of mollusks except bivalves (organisms with two shells such as clams).
The Mollusca are a LARGE phylum of invertebrate animals which includes Bivalves (which filter feed), Gastropods (which have radulae and even some with poison harpoons), Cephalopods, Squid and Octopus (Which have beaks and arms with suckers and hooks), Aplacophora (some of which are parasites). There are probably more ways in which mollusca have found to fee than has been mentioned here but his answer gives you an appreciation of the range of methods that have evolved.
No, it is found in every class of mollusc except the Bivalve.
Mollusca is indeed a very large phylum, with bivalves, gastropods, cephalopods, monoplacophorans, scaphopods, aplacophorans and chitons. However, this is not nearly enough to cap the largest phylum, which is ....... Phylum Arthropoda, with about 1 million insect species, and plenty of myriapods, arachnids and crustaceans, not to mention horseshoe crabs and pycnogonids.
i think you mean what is a Mollusk? Mollusks are invertebrate animals belonging to the Phylum Mollusca. They have a soft body consisting of a visceral mass containing the internal organs, a muscular foot used for locomotion, and, in all mollusks except the bivalves, a head. In addition to the mouth, which may be located at the end of an elongated organ called a proboscis, the head often bears sensory tentacles and eyes. The mouth leads into a chamber known as the pharynx, which usually contains a radula, a flexible, ribbon-like structure consisting of numerous rows of minute teeth, used in obtaining food. In all mollusks the body wall surrounding the visceral mass is prolonged into a fleshy or sheet-like mantle, which usually contains glands that secrete the shell.
Every mollusk except slugs, which have evolved to not need a shell, has a shell. Snails, clams and other bivalves have an external shell. Octopi, squid and cuttlefish have an internal shell.
You can specialize in becoming a doctor or a firefighter. It can be anything except things like living and walking.
Pigs didn't really have a job except for feeding people.
well, there are lots, so i`ll just say mammals,birds,fish,reptiles,amphibians,sponges,echinoderms,mollusks,and cnidaria.
you feed them the same flakes you are feeding the adults except you grind it into a fine powder.
No. Most can except some specialized ones such as brain cells, red blood cells and gametes.
The same as an in any other specialized endeavor. There is no seperate laws for sports (except for the rules they are played under).
