Aside from the lack of genitalia, the lack of a mate of a mate showing up is just as much evidence for the creature not belonging to a pair bonding species much less a social species. Bears, Cats, Weasel, and many more just meet up and ditch. Just felt like pointing out that it is a huge leap in logic to gleam that a creature reproduces asexual because there isn't any partner to look after it. Hell, even if it were pair bonding or at least social enough to have help during this period, it's partner could just as likely be dead.
Just...please, be more consistent with the logic. The lack of genitals was a good observation, dump the rest of that crap.
