Semi aquatic herbivores, the U-watsi live in tight-nit family groups. Females carry their "exposed fetuses" up to the birthing, where they then expel, the fully capable offspring, into bodies of water. There the chicks will grow and undergo their metamorphosis to their adult form.
A symbiotic relationship is common between the U-watsi and Ka-wenu. while the U-watsi has a superb sense of smell the Ka-wenu has keen eye sight. The Ka-wenu also feeds on parasites especially those which are detrimental to the fetal growth. Ka-wenu are highly territorial of their U-watsi, especially male U-watsi, as female Ka-wenu lay their single egg within their dorsal fans.
I put a little hight comparison chart there to help everyone get a better understanding of scale.
