Earthworms can be released, which Buddhists say is good. Scientifically speaking, earthworms are beneficial insects, which can loosen soil and benefit plants.

Don't let them fall apart, such as many turtles. You know, there is a species called Brazilian tortoise, which is an alien species. It is extremely aggressive and breeds rapidly, which will destroy the ecological balance and cause more biological deaths. I still don't think it's release, it's killing. Scientific and reasonable release is a blessing.
