These are from a friend to help teach the kids about different species and their growth an development... Now i cant remember what the one on the right is, its young not sure if i will even be able to get an i.d for a while
I think its a ephippiata or a tentaculata but leaning more towards ephippiata, any guess is appreciated.

It's nearly impossible to tell right now. You'll have to grow them out to know!

Ahrg... Such a pain i hate teaching the kids and saying 'unknown' lol! I should have put the lables on it with marker instead of tape

Its either this ones ephippiata or tentaculata or this one is tentaculata maybe this would be easier to i.d so then i have a netter chance at guess. Cause i kno the one on the left already (thank goodness!) lol
