Does it have a pole and a hole and can it fuck and impregnate itself?

Animals that reproduce asexually include planarians, many annelid worms including polychaetes and some oligochaetes, turbellarians and sea stars. Many fungi and plants reproduce asexually. Some plants have specialized structures for reproduction via fragmentation, such as gemma in liverworts

Spiders are bizarre sex freaks.
But it’s all harmless fun ... no wait, actually it’s very harmful. Girl kills guy or guy kills girl — there’s shrill crying, plugged orifices, torn-off genitals, eaten body parts, and psychedelic rituals.
And you thought humans had crazy sex lives? Mounting evidence in recent years shows just how crazy spider sex is.
For example, in the case of redback spiders (Latrodectus hasselti), courtship tends to last an average of 50 minutes when males are competing head-to-head for mating rights and 4.5 hours for single, non-competing males. It seems as if the larger male redbacks would always be favored, but scientists recently discovered that the smaller ones actually get more actionthan their bigger counterparts because they mature faster and are quicker on their feet.
Meanwhile, mature jumping spiders sport crucial glowing patches on their bodies to lure in mates, as if dressed for a rave. The males exhibit UV-reflecting scales that glow in bright white and green, and the females’ have front appendages that similarly glow in a bright green hue.
Turns out, females and males will ignore each other if not seen under full-spectrum light, suggesting that both partners must show their glowing bodies to prove their health before courtship can proceed.

In the case of redback spiders, courtship tends to last an average of 50 minutes when males are competing head-to-head for mating rights and 4.5 hours for single, non-competing males.
Spiders reproduce sexually, however the male's sperm is not inserted into the female's body from within the male's genitals. Rather an intermediate stage takes place. Males ejaculate onto ready-made small sperm webs and then transfer their sperm to syringe-like structures on the tips of their front appendages, or palps. As courtship progresses for the male jumping spider, he will arch his body, vibrate his palps and slink on tiptoe toward the female. If courtship is successful, the male injects his sperm from his palps into the female’s genital opening, known as the epigyne, on the underside of her abdomen.
In the Tidarren argo species, the male will amputate his own palp before he matures to improve his own mobility, only to have his remaining palp torn off by his mate, which stays attached to her epigyne for about four hours, independently transferring sperm into one of her seminal receptacles.
Female spiders are able to store sperm from different males inside their bodies and can choose which male gets to fertilize her eggs. As a result, the males in two different spider species treat their respective female partners in completely different ways:
