I was asking about earthworms, sorry for not being specific. Thanks!

How/where did you get the info? I would love to read it for myself. My 13 year old son says live births & I say eggs. Thanks for helping us figure it out.

for the question, they hatched from cocoons(or eggs) only.
the facts is here:

http://sps.k12.ar.us/massengale/earthworm%20facts.htm

And the link below is the fact about It's regeneration skill

enjoy reading.

additional info:

Same species are able to regenerate amputated segments of the body. Regeneration of tail segments occurs more readily than head segments. There does seem to be a limit to the number of segments that can be regenerated, but this number varies from species to species. No known worm species, if cut in half, will form 2 viable worms.

The common earthworm or nightcrawler of our lawns, gardens and bait cans, has a body made up of a series of 100 or more segments marked off by shallow grooves. If the worm is cut in half, the head end can grow a new tail. The tail end, if it lives at all, grows another tail instead of a head and eventually starves to death. If only 15 or 20 segments of the head end are cut off, they are replaced by a new head with but five segments.

They cannot reproduce by regeneration, two separated part earthworm can not grow into two happy earthworms.

The more parts you cut them off, the more possibility all of them will die.

Depends on the Wroms.

Earthworms split in half and the two halfs frow.

Some parasite worms lay eggs.

Others like the worms that dogs get, have a wierd cycle. you will have to look it up though as I don;t really remember

Either of two things: by being born alive or by regeneration.

Those born alive are the tiny earthworms you see. Then they grow to be bigger earthworms.

Earthworms have segmented bodies. If detached, these broken bodies regenerate and grown into two earthworms out of one earthworm. The more segments you cut, the more number of earthworms you produce.

doggies are born with worms, yet whilst he grew to become into dewormed 4 cases in the previous you obtain him, he shouldn't have worms now. of direction the breeder might have lied to you approximately that. If the worms you notice are small on the subject of the size of rice, then it quite is tapeworms and that they desire a distinctive wormer for that. Tapeworms at the instant are not existence threatening. the different worms are not the two till he has a multitude of them. verify out his gums. Are they pink or white? in the event that they are pink, it quite is going to be okay to circulate to vet in 2 days. in the event that they are white, he should be considered by using a vet asap. he's amazingly anemic. To the guy who suggested doggies should not be wormed in the previous 6 weeks, they are incorrect. practically each and every breeder will start up worming their doggies at approximately 2-3 weeks previous and each week thereafter till 6 weeks, then each and every 3-4 weeks.

Earth worms are hatched from eggs. Try looking at vermiculture where information on life cycle of an earth worm is available.

It's not live birth, only mammals reproduce through live birth (except, of course, for egg-laying mammals like the platypus).

Earthworms reproduce asexually -- they spawn a copy of themselves
