Gastropods undergo torsion as they develop?
yes.
The developmental process in which one side of the visceral mass of gastropods grows faster than the other and twists around by as much as 180 is known as?
The developmental process in gastropods where one side of the body grows faster than the other, causing the visceral mass to twist is called torsion. This torsion usually causes the anus and gills to end up above the head in adult gastropods.
How do gastropods undergo torsion as they develop?
Gastropods undergo torsion during their larval development, a process where the visceral mass, shell, and mantle twist 180 degrees relative to the body. This rotation occurs during the veliger stage and results in the anus and mantle cavity moving to a position above the head. Torsion allows for a more compact body plan and facilitates the retraction of the head into the shell for protection. However, it also presents challenges, such as the potential for excretory products to contaminate the gills, which have led to adaptations in their respiratory and excretory systems.
Do gastropods have bilateral symmetry?
Gastropods, a class of mollusks that includes snails and slugs, exhibit bilateral symmetry during their larval stage. However, as they develop, many undergo a process called torsion, which leads to a more asymmetrical adult form. While they retain some aspects of bilateral symmetry, the torsion can result in a significant deviation from perfect bilateral symmetry in their adult forms. Therefore, while they start with bilateral symmetry, their adult forms are often asymmetrical.

How do gastropods circulate?
Gastropods have an open circulatory system. Check related links.
If a slug have no shell are they gastropods or cephalopods?
Slugs are gastropods. All slugs are shell-less.
Is a snail an insect and why?
No, they are gastropods; animals that grow their homes.
Are gastropods extinct?
No.Don't you realize that gastropods are snails and slugs and such?If I'm right, none of those are extinct.
What is the circulation of gastropods?
Gastropods have a closed-circulation because it has ventricles that carry blood throughout it's body.
Where do Gastropods live?
the ocean
