Slugs don’t have outer shells because they evolved from snails and lost their external shells over time . They no longer needed these shells because they found ways to survive without having a shell to hide in for protection or using a shell to store their internal organs.
For example, if slugs are at a disadvantage because they do not have a shell, then they will be outcompeted and become extinct. It turns out that losing the shell is not such a big handicap, because slugs can get into crevices that snails cannot by losing the shell.
A query we ran across in our research was “What is the difference between snails and slugs?”.
Snails are shell-fishly hoarding all the shells. Slugs belong to a group of animals called molluscs. While slugs have no apparent shell, some species may have a reduced shell, or one that is internal, and therefore not visible .
Why don’t any animals eat slugs?
Slugs are chemically protected. They taste disgusting to most animals that might want to eat them. We eat escargot ourselves, but never slugs. Interestingly, sea slugs are also protected without shells, though by a different mechanism .
Slugs have evolved from snails many times (in different families/superfamilies of snails), There are a number of “semi-slugs” that have external shells too small to withdraw into. Slugs lose the protection of the shell, but avoid carrying the weight, and the considerable expenditure of energy needed to make it.
What is the habitat of a shell?
In freshwater habitats. Shells found in freshwater habitats are members of two major classes i., and e. They occur in both calmer waters (e. g. ponds, small lakes, still waters near river and stream banks) and running waters (brooks, small and larger rivers, in breaker zones of lakes).
Also, are there shells on the beach?
Not all will be found on beaches frequented by tourists. In fact there are relatively few shells to be found along our beaches and they are mostly small bivalves . These shells came from the New Smyrna Beach area and Ponce Inlet.

Some think that because of the limestone’s greater resistance to erosion, the towering cliff remains, revealing its trove of seashells. We’ve found seashells from shore to shore, on mountaintops and places in between. Chances are, you have seashell fossils in geologic formations in your home state .
What shells does the judge use?
The Taurus Judge is a five-shot .45 Colt revolver with an elongated cylinder that allows it to chamber 2½-inch or 3-inch . 410-gauge shotgun shells (depending on the particular model). Because the barrel is rifled, the Judge is not considered a sawed-off shotgun or “dangerous ordnance” by federal law.
In other words, much like how one should test any ammo they plan on using for self-defense in a semiautomatic pistol, the same rings true of the Judge.
Judges were buying this gun because the .410 shotgun shell offered less chance of over-penetration in the courtroom than standard revolver cartridges, including the .45 Colt. Taurus sent me a 3-inch barreled M4510 stainless steel Judge with 3-inch chambers to evaluate.
What size shell does a Taurus Judge shoot?
Shotgun shells are either filled with birdshot as a 2.5 inch size with various weights, or most buckshot as a 3 inch shell. Most Taurus Judges handle a variety of 2.5 inch shells, but as mentioned, the 6.5 inch barrel model does have 3 inch shell capabilities..45 Colt Particulars.
What kind of ammo can you put in a Judge revolver?
The 5-shot cylinder has been lengthened to accept up to 3-inch .410 shotshells. As for the factory specifications, the Judge featured herein is a standard double-action revolver that will accept all .410 shotshells in 2 1/2- and 3-inch varieties as well as .45 Colt ammunition.
