Simalgeara pavimentus
S. pavimentus is a unicellular organism that feeds on waste that has fallen to the seafloor of Zone 1. S. pavimentus evolved from populations of S. gastrous that fell to the seafloor when they excreted from their hosts along with waste or when their hosts corpses sank. Having no other option, these S. gastrous began feeding on what they sank with. After finishing what they came in on, they began to spread to and feed on the other waste present in the benthic zone of Zone 1.
Adaptations: S. pavimentus have lost some of their ancestral carotenoids as they are no longer needed as photosynthesis is impossible on most of the seafloor. Other than that, despite no longer living in hosts, not much has changed about them structurally, as ancestors such as S. orangesis lived without hosts and S. gastrous did not possess any host-specific adaptations.
Feeding: S. pavimentus use digestive enzymes similar to those of their ancestor to break down and feed on detritus, such as feces and the sunken corpses and remains of the multitude of flora and fauna present in Zone 1.
Reproduction: S. pavimentus reproduce asexually through division. They reproduce more often when in the presence of food.
