Starfishs or seastars have sexes( they are either male or female) but they can reproduce both sexually and asexually. The latter is possible using fission or fragmentation.
In this planet there is a race of sentient starfish that has similar intelligence level as humanss and they are bipedal which means that they can walk, talk, feet and have a face but use the same methods of reproduction as real life starfish. They can use budding, fission or fragmentation for assexual reproduction and sexual reproduction as well. They live on land like humans do but they can live in water in the same way as crabs do.
Both males and females can reproduce asexually or sexually but since they have intelligence and therefore ethical values would they opt for asexual reproduction if they could mate with a seastar of the opposite sex? Would they think it is selfish to reproduce asexually even if it is easier and less costly than sexual reproduction? Would they think that people need to hae two parents and not only one?
Most people think that children need two parents for a good mental and psychological development but humans cannot reproduce asexually.
Note: I imagined this race of bipedal seastars based on a speculative evolution video that I watched on YouTube.
