Question

Which of the following is/are components of a snail's body?
A. Visceral mass
B. Shell
C. Ventral muscular foot
D. All of the above

Answer 1

Hint:
Snails are mostly categorized as water and land snails. There are great differences between these two. Both the species have great differences including both anatomical and morphological features.

Complete step by step answer:
Option -A- Visceral mass
The visceral mass or otherwise named as a visceral hump in snails or other molluscs are always present inside the shell. It is known to hold the bulk of organs of each system or it holds internal organs in the snail body. It contains the bulk of the organs of respiratory, digestive and reproductive organs of the snail.
Option -B- Shell
Yes, snails have a shell which is made up of calcium carbonate which is a hard element of the shell. This shell keeps growing I.e. keeps adding calcium carbonate as long as the snail grows. The function of the shell in snails is to protect their soft body along with their internal organs which are among the most important lungs. The shell in snails can be of many shapes and different sizes depending on the species. The shell also serves as the function of protection from the environment and the predators.
Option -C- Ventral muscular foot
Although in snails they do not possess legs instead they have a special ventral muscular foot which allows them for movement. With the help of these snails can move from one place to another or these allow snails to move forward. This action of snail is very smooth and safer as they secrete mucus which allows free movement of snails even on frictionless surfaces and therefore avoids any harm to the body of the snail.
Option -D- All of the above
This option is the correct description for the question as all the above-mentioned options are the correct description for components of the body parts of the snails.

So, the correct answer to this question is the option"D" all of the above.

Note:
Snails are categorised under Gastropoda which is an important class which comes under the phylum Mollusca. They are known to continuously evolve throughout time. They are known to be found in various habitats and require a large amount of food for their survival. Snails are mostly hermaphrodites meaning both the sex organs are present in one individual.
