Safiyaziwa

If someone collected a cup of water from the lakes and swamps of Yama about 440 million years ago the most likely species they would find are the microscopic Safiyaziwa or "lake cleaners" in English. These diminutive descendants of Xenoeuly kirbyi have adapted to be the basis of life in the freshwater ecosystems of Yama. They are responsible for the majority of waste management for these early freshwater systems. Pictured here is famed Xenobiology 1 paleoartist Sean Ring's painting of Safiyaziwa.

Basic Information

Anatomy

Safiyaziwa have lost many of their ancestral Xenoeuly segments, with only four remaining. The first segment is the head consisting of a simple mouth, elongated flippers for mobility, external gills and a pair of simple eyes. The following three segments repeat this process though the flippers and external gills begin reducing in size and are positioned more posteriorly. These smaller limbs are used primarily for holding onto eggs after mating. Mobility is the primary use of the elongated fins on the head segment.

Genetics and Reproduction

Safiyaziwa are true hermaphrodites who will gather to spawn several times a year usually after rainfall. Members will perform a cloacal kiss, exchanging gametes and separating. They will do this with several partners to increase genetic diversity. After two local days the Safiyaziwa will lay on average 40 eggs that it will carry with its gills and fins until they hatch.

Growth Rate & Stages

Safiyaziwa emerge from their eggs on average 7 local days as miniature versions of the adults. They will reach adult size in on average 60 local days and will be able to breed in an additional 30 local days.

Ecology and Habitats

Safiyaziwa are found exclusively in the freshwater ecosystems of Yama preferring slow moving water as fast moving rivers will often wash them away.

Dietary Needs and Habits

Safiyaziwa are detritivores who feed on retinalphytes, decomposing material and fecal matter of other organisms.

Additional Information

Perception and Sensory Capabilities

The eyes along Safiyaziwa’s dorsal side are small and simple, only being able to distinguish light from dark.
