How do sea cucumbers breed offspring?

Different kinds of sea cucumbers have different propagation modes, which can be roughly divided into two types: 1. When reproducing asexually, it will twist its body like twisting clothes. After a few days, a sea cucumber will break into two pieces, and then each piece will grow separately; After reaching a certain length, it can repeat asexual reproduction and become two sea cucumbers again. Therefore, we can know from its breeding mode that as long as there are sea cucumbers, you can always grow more sea cucumbers through methods, but once there are no sea cucumbers in the local area, there is no need to twist them and there is no way to reproduce them through asexual reproduction. 2. Traditional reproductive mode The traditional reproductive mode is that sperm and eggs are discharged into seawater for in vitro fertilization, and then the embryos develop in water and drift for many days to find a suitable habitat for growth. However, when they reproduce in this way, their offspring usually drift far away. In this way, it takes considerable luck and patience to get the care and favor of one or two sea cucumbers along the coast.
