Typically yes! It's a survival technique. Snails normally lay their eggs in the dark. To help encourage laying you can drape the aquarium with a towel or blanket.
Snails are nocturnal, so are more active in the dark, but do not need to be in the dark.
reproduce and do snail slime stuff
Snails are more active in the dark because at night, it is cooler at night than in the daytime. Snails have to stay moist to survive.
Yes. Most land snails live in dark, moist places.
Dark and damp
Both, though mass asexual reproduction in snails is uncommon. Mainly because of the genetic disadvantages. An example of this is in the asexually reproduced offspring of the species Potamopyrgus antipodarum which have a higher rate of disorders and mutation. thus natural selection removes most of them.
Yes, some species of snails can reproduce with only one snail present.
Snails are dark brown. :)
Most snails are hermaphrodites. This means that they are both male and female. All hermaphroditic snails can lay eggs. They can "mate" with themselves and thus only one can reproduce in an aquarium or pond. They also breed sexually as often as possible. Most snails lay eggs but some, like the trapdoor snail, give live birth. Trapdoor snails and a few other species of snails (apple, golden inca, four horned, etc.) are not hermaphrodites. They can only reproduce sexually.
Scientists refer to aquatic-snails nests appearing bubble-shaped or similar to a cocoon where pairs of snails reproduce every 6 days or few weeks.
Most snails lay eggs, but some are live-bearing snails, such as the Malaysian Trumpet Snail. Most snail species are hermaphroditic, meaning they have both male and female reproductive organs. However, apple snails are one of the few exceptions to this rule. Snails typically reproduce sexually, although some species have been known to reproduce asexually.
Sometimes they are brown. Sometimes they can be a green-ish color too.
