Torsion
yes.
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.
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.
How do gastropods function as decomposers?
No, snails are gastropods.
Gastropods have an open circulatory system. Check related links.
Slugs are gastropods. All slugs are shell-less.
No, they are gastropods; animals that grow their homes.
No.Don't you realize that gastropods are snails and slugs and such?If I'm right, none of those are extinct.
Gastropods have a closed-circulation because it has ventricles that carry blood throughout it's body.
