How do snails excrete waste?
From the gastric pouch, waste enters the intestine and rectum on its way back out of the body. Land snails excrete the
undigested parts of their food from the anal pore
, located in the mantle, at the edge of the shell in shelled species. Snail excrement may appear as a tiny folded rope.
Where are snails private parts?
These two types of snails still have separate male and female individuals. The reproductive system ends in an external opening located in the lower part of the body near the head, called
the genital pore
. Individuals reach sexual maturity at different ages, according to their species and their particular conditions.
How long do snails live for?
Most snails live for
two or three years
(in cases of land snails), but larger snail species can survive up to 10 years in the wild! In captivity, however, the longest known lifespan of a snail is 25 years, which is the Helix Pomatia.
Do snails have feelings?
But animals with simple nervous systems, like lobsters, snails and worms,
do not have the ability to process emotional information
and therefore do not experience suffering, say most researchers. “There are two types of animals, invertebrates and vertebrates,” said Craig W.

. “Poop” comes out the anus on the side of the shell and falls to the ground.
Do snails have a immune system?
This time, the presence of micro-organisms induced a strong phenoloxidase response but no antimicrobial activity. Their results overall highlight the complexity of the snail's immune system, with trade-offs occurring between different pathways. It seems that
the immune system of the snail remains a mystery!
How do snails help the environment?
Land snails serve an important role in the ecosystem.
They eat very low on the food web
, as most land snails will consume rotting vegetation like moist leaf litter, and also fungi and sometimes eat soil directly. … Many birds rely on snails for the extra calcium they provide.
Are snails male or female?
Most land snails, or pulmonates, are hermaphrodites, meaning they possess
both male and female
sexual organs. However, land-oriented prosobranch snails, as well as many water snails, are dioecious, meaning they can be either male or female.
Can snails mate with themselves?
Different snails reproduce differently, but most snails are “hermaphrodites.” Being a hermaphrodite means that any given snail can be both male and female at the same time. … Some hermaphrodite snails do not need another snail to reproduce, but
can make more snails all by themselves
(this is called asexual reproduction).
